    Purpose The purpose of this paper is to examine the factors (including conservation payments) that influence household decisions to participate in off-farm work and estimate the impact of participation on household welfare under the auspices of the Grain for Green (GfG) program. Design/methodology/approach The authors used survey data from 225 farm households on the Loess Plateau and addressed the possible sample selection and endogeneity problems by employing a jointly estimated endogenous switching regression (ESR) model. Findings The findings of this paper are as follows: off-farm participation is positively related to households' educational attainment and negatively related to their land resource endowment and the presence of children; participation in off-farm work exerts positive effects on household income and per capita household income, but negative effects on farm productivity; and conservation payments show no significant impact on off-farm participation, no significant impact on any of the three household welfare indicators for off-farm non-participant households, but a significantly negative impact for off-farm participant households. Originality/value This paper makes two contributions. First, the authors address the selection bias and endogeneity problem of GfG participating households by employing the ESR method and explicitly estimating the treatment effects of off-farm participation on their household welfare. Neglecting these problems leads to biased estimates and misleading policy implications. Second, this analysis stresses the important role of government in reducing market or institutional failure and other barriers that impede farmers' efficient allocation choices instead of compensating households for conserving sloping land, shedding new light on the most effective policy options to achieve the program's goals.

    This study provides an empirical analysis of household technical efficiency and its determinant factors (especially conservation payments) in the context of the Grain for Green program. On the basis of a sample of 225 farm households on the Loess Plateau in 2007, we estimate household technical efficiency using the data envelopment analysis method. In addition to a traditional ordinary least square (OLS) analysis, quantile regression (QR) analysis is also deployed to explore the possible heterogeneous effects of conservation payments and other variables on the technical efficiency across the quantiles. The results suggest that when off-farm activities are taken into account, households have considerable potential for improving their technical efficiency; OLS analysis shows that conservation payments decrease household efficiency, and the QR analysis suggests that the negative impact is significant only for higher performance households; The presence of children, access of households to leased land markets, credit markets, and extension services all show heterogeneous impacts on household efficiency. On the basis of the findings of the study, policies suggestions to improve the program’s effectiveness are provided.

    In the Computable Urban Economic (CUE) Model, one land-use transport interaction (LUTI) model, improving the accuracy of the Location Choice Model is important to evaluate the effects of introducing urban transportation policies. However, our previous study revealed that the substantiation of the indirect utility function by a linear expenditure system has not been verified and that location choice behaviors estimated using the logit model depends on the adjustment factor. Therefore, in this study, we first examined the logical meaning of the utility function by a linear expenditure system, and then focused on identifying major constituent factors of the adjustment factor and statistically verified the adjustment factor and urban amenities. As a result, we have identified the following facts: that the conventional indirect utility function may underestimate the effect of introducing urban transportation policies; that if effects are estimated using WLS after adding housing supply factors to the indirect utility function, the estimation accuracy will be improved; and that the major constituent factors of the adjustment factor are those expressing local characteristics of cities and wards.

    Over the last two decades, there have been several studies on productivity related to transportation investments in not only Japan but also several foreign countries. However, these prior studies did not achieve common results as they did not use a unified format for measuring the service level of the transportation network and using the dataset. Therefore, this study classifies previous studies from six points of view. These are analytical method, functional type, explained variable, service level of the transportation network, aggregation level, and estimation method. This study examines the differences in results caused by the diversity of analytical methods. In addition, this study estimates the production function using two analytical methods with Japanese data. Then, the relationship between the productivity and transport investments is revealed. From this result, several issues are confirmed.

    This paper develops a short-run economic damage assessment model. The model contains two sub models. One is the conventional traffic assignment model, which calculates traveling time under the damaged transportation infrastructure. The other is the economic damage assessment model, which determines the decrease in production level in the short run. This method facilitates the identification of critical infrastructure that could reduce the economic damage when the disaster occurs. As a case study, we applied this model to several recovery plans for transport facilities. The results suggest that the proposed comprehensive model should be considered as a prevention plan.

    In this paper, regional financial computable general equilibrium (RFCGE) model was developed. The RFCGE model is a useful tool in the evaluation of regional fiscal policies. So far, computable general equilibrium (CGE) models have often been used to evaluate regional infrastructure investment policies. However, conventional CGE models do not consider financial assets, such as deposits, equities, and government bonds and decision- making mechanism of government. Therefore, applying CGE models might overestimate the benefit incidence of policies on the rural society. To confirm this theory, the RFCGE model was applied to regional infrastructure investment policy.

    By using a travel demand forecasting model that covers both inner-city and inter-city transportations of whole of Japan, we discuss economically efficient regional CO2 emissions reduction quotas. We calculate the CO2 emissions reduction by introducing a fuel tax as a countermeasure against global warming at each region and illustrate the results can be applied to decide the regional quotas. In our analysis, it has been shown that the CO2 emissions reduction per capita due to the taxation, which is equal to the region's reduction quota per capita, is bigger in rural areas than in urban areas.

    The purpose of this paper is to develop the SCGE model for finely-divided regions in order to conduct positive analysis and estimate economic impacts. In our study, the model deals with 2,342 cites in Japan and takes into account inter-regional freight transport, commuting and capital flows between each city.
    In the positive analysis, the developed model is applied to the case of Great East Japan Earthquake. The damage of the earthquake is expressed as decrease in the production efficiency of firms, which is assumed to be equivalent to the rate of capital stock decrease in the inland and coast regions in the suffered area, i.e., Iwate, Miyagi, Fukushima, and Ibaraki Prefecture. The result shows not only that large economic damage has occurred in these suffered areas, but also that the economic damage has affected all East Japan and industrial areas of Chubu, Kinki, Chugoku and Kyushu District.

    Road networks can be considered local public goods. Hence, if they are to be efficient social choices from an economic perspective, their spatial benefit incidence should be equal to their cost burden in each region. An analysis of benefit incidence should consider not only a usual scenario but also a disaster scenario because the redundancy effect is expected to reduce the amount of economic damage incurred during a disaster. The authors' research group has developed a spatial computable general equilibrium model (RAEM-Light) that can be applied to small spatial regions. The RAEM-Light model was used to analyze the benefit incidence in the development and maintenance stages of proposed road networks under a usual and a disaster scenario. The spatial incidence of the economic effect of road investment differs between the usual and the disaster scenarios for both the development and maintenance stages. As Japan becomes more decentralized, it will become more important to determine the optimum allocation of the road-network cost burden among local governments, taking into account differences in the spatial benefit incidence at each stage and in each scenario. However, to minimize the economic losses incurred by a disaster such as the Tohoku earthquake (March 11, 2011), more centralized decision making may be necessary, although this is not efficient social choice from an economic perspective.

  • Efficiency and its determinant factors for smallholder farms in the Grain for Green Program on the Loess Plateau, China

    Li Li, Atsushi Tsunekawa, Mitsuru Tsubo, Atsushi Koike, Jijun Wang

    A nonparametric frontier approach, data envelopment analysis, was used to calculate technical, pure technical, cost, allocative and scale efficiencies of 112 farms participating in the Grain for Green Program on the Loess Plateau in China. The results indicate substantial cost inefficiencies. The main source of cost inefficiency was allocative inefficiency although considerable technical inefficiency also exists. Technical inefficiency resulted slightly more from scale inefficiency than from pure technical inefficiency. Scale inefficiency was mostly due to the suboptimal scale of farms. Regression analysis of explanatory variables against technical efficiency, allocative efficiency and scale efficiency suggested that LG_Agri (indicator for farm size) was the only variable that was significantly related to all three efficiency indices. Other significant variables include Remittance Ratio (indicator for rural-urban migration), Tenancy Ratio (indicator for land tenancy) and Simpson Index (indicator for land fragmentation). Our findings prompt policy suggestions that would facilitate labor mobility, provide more secure land tenure and increase land consolidation, while avoiding further withdrawal of cultivated land unless explicit measures to alleviate the potential impact on production efficiency are followed.

  • Assessing total factor productivity and efficiency change for farms participating in Grain for Green program in China: A case study from Ansai, Loess Plateau

    Li Li, Atsushi Tsunekawa, Mitsuru Tsubo, Atsushi Koike, Jijun Wang

    In 1999, the Grain for Green program (also known as Sloping Land Conversion program), one of the world's largest land-conservation programs, was launched in China. It emphasizes both eco-environment rehabilitation and poverty alleviation, with the ultimate goal of sustainable development. Total Factor Productivity (TFP) has important implications for conservation of the environment, enhancement of wellbeing, food self-sufficiency, and the sustainability of the program. Using data from the year before and the ending year of the first phase, we did a case study in the Zhifanggou watershed on China's Loess Plateau. We used a Data-Envelopment-Analysis based on Malmquist TFP index approach to find out the changes of TFP, the sources of TFP growth, and the determinant factors at a farm level. We found that 1) TFP has been greatly improved after the implementation of the program and 2) the sole source of TFP growth is technological growth. In contrast, the technical efficiency of farms under the improved technology has decreased; 3) farms with an unfavorable initial state benefited more after the introduction of the program; and 4) land terracing and access to credit contributed significantly to TFP growth and technological growth. Land terracing is positively related to technical efficiency change, too. Extension services are positively related to technological growth, while age is negatively related to technical efficiency change. We therefore suggest a focus on terracing slopes, improving access to credit and extension services.

    The authors apply the RAEM-Light model to analyze the distribution of social benefits from expressway network projects from the viewpoint of spatial equity. The RAEM-Light model has some innovative features. The spatial behavior of producers and consumers is explicitly described and is endogenously determined by using econometric production and consumption functions. This model applies a slightly different concept than the traditional spatial computable general equilibrium model that does not depend on the input-output data. It is therefore well suited for analyzing detailed areas for which official input-output data are not available (i.e., its zones are subdivided into a neighborhood area level). In this paper, the authors analyze two expressway network scenarios. In Scenario 1, the regional economic impacts from the present expressway network are simulated. In this base case simulation, it is concluded that the present expressway network has a low score on spatial equity, in particular because of negative impacts on rural areas. In Scenario 2, the authors analyze the present and future expressway network case in rural areas. As compared with Scenario 1, negative impacts from the implementation of the expressway network are reduced, especially in rural areas. This comparative analysis quantified the effectiveness of the two network structures from the viewpoint of spatial equity. Theoretically and quantitatively comprehensive studies from the viewpoint of spatial equity on the effects of infrastructure development have not yet been sufficiently conducted; however, the results of the comparative analysis are promising for an economic assessment of the expressway networks from the point of spatial equity.

    In this chapter, we develop a SCGE model that covers the entire nation of Japan to clearly analyze the spillover impacts of the Haneda airport project. We then describe the spatial incidence of the project's benefits. Benefit incidence is summarized in a benefit incidence table (BIT), which clearly shows the canceling out of indirect benefits and distribution of benefits by region and economic sector. Major findings include (i) the expansion of Haneda can bring a large amount of benefit to all regions in Japan, particularly peripheral regions and (ii) consumption at trip destination increases in Hokkaido, Kanto, Kyushu, and Okinawa.

    This chapter focuses on strategic actions of local governments to enrich aviation services to their local airports, and analyzes the influence of these actions on the formation process of aviation networks. Air service development action gives an influence not only on the airport but also on other airports because of the existence of network externality. This study models such an interdependent and path-dependent situation as a repeated n-person non-cooperative game. Numerical analysis shows that competition between local governments using subsidies for petition flights forms a regional hub endogenously under certain conditions.

    本研究は、南海トラフ地震などの巨大災害がもたらす国民経済への影響と対策の効果について、定量的な分析を可能にするシミュレーションモデルを構築し、今後実施されるべき我が国のレジリエンス強化施策の必要性や妥当性を検討するための技術的な枠組みを提供することを目的としている。 2018年度に実施したのは、主として、道路ネットワークに関する予測モデルの構築である。高速道路、国道、都道府県道、市町村道のそれぞれについて、道路の特性(耐震化の状況、電線類地中化の状況、道路周辺の土地の利用形態、等)と地震の規模等(震度及び津波浸水)に応じて、道路リンクが破断つまり利用不可になる確率を求めるモデルを構築するため、必要なデータの収集と、数パターンの分析を実施した。東日本大震災時の道路インフラの特性と被害データを用いてモデルを構築するが、被害については、特定の道路リンクが破断したか否かを示す直接的な調査データは存在しないため、震災前後の民間プローブデータから、道路リンクの破断状況を推測することとした。 分析の結果として、入手可能なデータから一定の精度で道路の破断確率を求めるモデルが構築されたと言える。既存の研究においては、交通インフラに関する実務的に利用可能な被害モデルが十分には検討されてきていないため、南海トラフ地震をはじめとする将来発生が予想される震災の被害予測に向けて有意義な前進ができたと言える。 ただし、橋梁の耐震化や電線類の地中化といったレジリエンス強化施策の効果については、効果が存在することは確認されたものの、その規模は想定したよりも小さなものであった。その原因として、東日本大震災時の耐震化や地中化の実施状況に関するデータが、十分に詳細な計測単位では得られなかったことが挙げられる。今後、より精度の高い分析に向けて、新たなデータの利用等を検討する必要がある。

    In order to decrease a risk in case of emergency such as traffic congestion due to catastrophic events, to build a double or triple network of highway seems effective. It clearly shows that new manufacturing factory locates in the area where the alternative route to major cities is developed. ”Redundancy Effects” in this study means that shortening of transportation time of the alternative route to major cities promotes manufacturing factory location. The purpose of this study is to estimate this effect by using fixed effect model. As a result of estimation, redundancy effects were observed in some areas. Many of these areas are far from the urban area.

    We have introduced the commons concept, which has been actively studied in the fields of environmental studies, economics, etc., to practical planning of architecture. And since we have been working as a researcher in Otsuchi Town, Iwate prefecture, based on the collection of memory testimony by model WS which is continuing support activities in Project Otsuchi Media Commons (MLA), we aimed to construct a commons regeneration model in the disaster area. We revised our research method due to the fact that it took time to compile the massive testimony gathered as practical data and of the town changed the policy the reconstruction project and delayed plan. We made a digital archive of model workshops and testimonies made experimentally in other areas and modeled how to utilize them.

    Although it is important to understand the influence of consumer behavior on regional economy, as far as we know, no empirical research has been conducted in Japan. Therefore, the purpose of this study is to verify the economic impact of consumer’s behavior on regional economy. We investigated two local merchants and four chain stores in Kyoto-city in order to compare the local economic return of consumption. As a result it was shown that if some shopping is done at local merchant, approximately 52% of consumption revenue will return to local economy, however if some shopping is done at chain store, the return rate will become about its half. This result suggests us about a desirable consumer behavior for regional vitalization.

    Spatial economic analysis requires an inter-regional trade data as monetary term like Input-Output table. Although the empirical policy study requires the analysis on subdivided area, however, we only have the Input-Output table on the 9 regional data in Japan. Therefore, this research shows the characteristic comparison between statistical data on inter-regional trade/freight data and inter-enterprise data by using simple statistical methods. As a conclusion, we show the inter-regional freight census data by MLIT and inter-enterprise data by TDB is effective index to subdivide into small region. But inter-regional freight census data is only for the prefectural level, inter-enterprise data can be applied at municipality level although we have to solve some problem to apply the model. Also, we make a model to estimate Gross transport data from Net transport data. It will be help us to estimate some inter-regional trade flow on subdivided are.

    The aim of this study is to clarify the relationship between social media information and returning home behavior in disaster. In order to analyze Twitter’s textual data, which is tweeted in the Great East Japan Earthquake on 11 March, 2011, this study applies text-mining approach. The results of text-mining confirm the trend of collocation’s network among terms after the Earthquake happened, and the distribution of term co-occurrence frequency. On the other hand, using the returning home data sets on 11 March, 2011 collected, this study calculate the differences of estimated population between one point and the former point. Moreover, using the two data sets, this study analyzed the relationship between both using a canonical correlation analysis. Term co-occurrence frequency in Social Media and behavior of returning home is applied to two sets of variables in canonical analysis, and the estimation results demonstrated that these two are significantly interdependent.

    This research focuses on the cooperative provision of inter-regional transport infrastructure by multiple local governments. A theoretical model is developed by employing general equilibrium modeling and non-cooperative game theory. With the model, strategic behaviors and therefore their consequent results such as a provision level of infrastructure are investigated. It is especially shown that decision timing and substitution/compliment characteristics of investment function play key roles.

    The aim of this research is to construct a base economic data in order to analyze social issues on rural areas. Traditional economic data is not enough to analyze these regions, because of resource on these regions is not only labor and capital but also time and social capitals. So, we proposed Rural Area Social Accounting Matrix in consideration of time resources and its applications. Use this data, we can find somefuture social issues from the numerical simulations.

    Japan is encountering population decrease and aging and has debt of 770 trillion. Local governments are in difficult situation due to the increase in people who need social welfare and budget deficit. Especially it is remarkable in small municipalities. Water supply, domestic waste water treatment and waste treatment are important jobs for a local government. These systems have been planned with the assumption of population increase until now. However we have to change our minds for depopulating age. In this research, new planning methodologies for depopulating age were examined. The overview about situation of small municipalities concerning population decrease and aging were shown and the subjects about planning and maintenance were indicated. Next, various methods to solve problems of environmental facilities due to depopulation and aging were examined. In facility developments, the choice method between concentrated system and diffused system was discussed. In maintenance method, planning about patrolling of diffused facilities and promotion method to use sewerage system were examined. The effects of sewerage system development method on municipality finance and local economy were examined. On the basis of the above practical studies, general methodologies were studied. The importance of satisfaction of each local governmental service from viewpoints of various age people and people's subconscious needs were emphasized. The methodology to consider spillover effect of projects was presented. The GIS technology for environmental control was examined.

    We conducted both theoretical and empirical analyses of policy assessments focusing on actual performances of economic policies. The analytical methods are economic theory, statistics, econometrics, and experimental economics. We regularly had meetings to check the processes and the results of works in progress, and finally published outputs of the researches. We form two research groups. One is a team to study environment, traffics and policy assessment, the members of which reviewed literatures of Japan and other countries about environmental and traffic problems such as garbage, industrial wastes, air pollutions, natural environment of sightseeing spots, and public transportation facilities. This group examined what kind of analytical methods and evaluation methods are suitable for these problems. Some of them carried out field surveys and hearing about the slow life and the recycling activities in the environmental policies of Italy. In addition, other members conducted cost-benefit analysis on the extension plan of the Osaka monorail, which is called "Saito project," with the choice experiment method. The other group specialized in the research of local public finance and the urban policy. They collected and analyzed data of sustainable growth of economies of remote islands and information disclosure problems of local governments. In particular, they employed questionnaire surveys to those who concern tourism of Amami Oshima Island and those who suffered from the Chuetsu earthquake. Some members also studied a tendency of convergence of income per capita based on data of the metropolitan area of Japan with Markov matrices. In the experimental economic analysis, other members showed that decentralized market mechanisms may not work out for unstable equilibria of perfect competition, or any types of equilibria of monopolistic competition. In the dynamic spatial general equilibrium analysis incorporated economies of scale, other members analyzed the influence of the traffic jam in the city part of the Netherlands from an aspect of the social economy and a living standard aspect, and investigated what influene congestions have on what type of industries.

    社会的要請から,社会資本整備の便益評価は,多くのプロジェクトで実施されるようになってきている.また,詳細な効果の帰着先を知る目的で,ミクロ行動理論に基づいた応用一般均衡分析による便益評価手法(帰着便益評価手法)が実施されるようになってきており,従来の需要予測に基づく消費者余剰による便益評価手法(発生便益評価手法)に変わろうとしている.しかし,応用一般均衡分析は,そのモデル構造が複雑なため,特定のパラメータの誤差が,最終的な便益評価にどれほど影響するかが明確でない.そのため,本研究では応用一般均衡モデルにおける誤差の整理とその便益評価に対する影響分析を実施することを目的としている.文献調査などの結果から,応用一般均衡モデルには以下のような3種類の誤差があると考えられる. 1)設定パラメータに含まれる誤差(例えば,代替弾力性パラメータの推定) 2)外性変数に含まれる誤差(例えば,政策変数の推定) 3)基準データセットに含まれる誤差(例えば,産業連関表の集計誤差) 本年度は,上記の誤差のうちで2),3)に関するモデル構築と実証研究を通じた推定誤差の範囲を特定し,最も重要なパラメータの特定化を行っている.その結果は,「社会資本ストック崩壊による経済的被害の空間的把握-空間的応用一般均衡分析による計量厚生分析-」(土木計画学研究・講演集),「47都道府県間産業連関表による震災被害推定のための空間的一般均衡モデル」(応用地域学会年次講演会)にて公表済みである.次年度以降,ある社会資本整備の評価を実施する場合にどのパラメータの精度に注意をすべきか,また,その場合の感度分析の指針を含めたマニュアル的な報告書をまとめる予定である.その結果は,便益評価結果の信頼性尺度とし,あるいは,評価モデルの妥当性を知る上で,大変重要であると考えられる.

    わが国の公共交通の歴史に残る"壮大な社会実験"とも言える乗合バス事業の規制緩和(平成14年2月施行)に対して関心を寄せている諸外国の研究者と共同研究を実施するための研究企画を行った.具体的には,共同研究を効率的に進めるための基盤形成を目的とし,以下の3つの点について検討を加えた. 第一は,"規制緩和に伴うバスサービスの変容に関わる情報のとりまとめ方についての概念整理"である.バスサービスの提供実態や影響の発現状況は地域特性や社会的環境と密接な関連を有しているため,費用関数の推定や生産性分析を予備的に行い,押さえておくべきデータ項目を抽出した. 第二は,共通の分析フレームの構築である.路線バス市場における供給側と需要側の行動は相互に影響を及ぼし合っており,規制や補助制度等が両者の行動を部分的に規定しているのだが,前述の地域特性や社会的環境とも密接な関連を有しているため,複雑な様相を見せている.そこで,関連諸要素を「利用者の活動水準曲線」「バス利用に関わる一般化費用曲線」「事業者の運賃設定曲線」等に整理するとともに,これらを相互に関連づけた分析フレームを構築し,個々の変化に対する分析の位置づけが容易に理解できるようにした. 第三は,国際共同研究を行うための研究体制の整備である.共同研究のメンバーとして予定している内外の研究者の関心は,"路線バスの規制緩和がもたらす影響の分析"という点では一致しているが,そのアプローチや着目点は必ずしも同一でない.研究組織を構成する研究者の研究アプローチと対象領域を整理し,作業の協力・分担関係を明らかにすることにより研究の推進体制を構築した. 以上により,政策が依拠する理論的基盤が教えるとおりの変容が生じたのか,それにより期待どおりの政策効果が得られたのか,を検証するための研究基盤を概ね構築しえたものと考えている.

    In this study, we developed an estimation method for Input-Output table at urban level and the CGE model for urban area in the context of open economy assumption. We first developed a method in order to construct input-output table at the urban area level using non-survey technique. When input-output tables are constructed, Estimation of interregional trade coefficients is important. In this study, we proposed a method for estimation of interregional trade using simple location quotient. And also, This research constructed a three-region interregional input-output model by dividing the whole country into three regions with the concept of hierarchical structure. In addition, we constructed a computable general equilibrium model in order to evaluate urban policy. Then, based on several case studies, we have shown that it is possible to conduct policy evaluation, using this model.
