Study On The Evaluation Of The Investment Effectiveness In "Grain For Green" Project Of West China

The grain for green project is a complex and systematic project which includes society, economy and ecology.It was proposaled in the case of China's western region's ecological environment worsening. It has great realistic significance and far-reaching historical significance to China's economic and social development and ecological construction.It is called"benevolent act works"by Chinese people.The basic policy measures: returning farmland to forests, closing off hill for afforestation, providing grain relief to make up for crop losses and contracting reforesting projects to individuals.In this study, a comprehensive assessment has been conducted on the investment model and structure of grain for green based on the theories of economics, ecology and land science. By using the method of cost-benefit, it performs a systematic analysis on the cost and benefit of grain for green on different stake holders. With this as the basis and by using the AHP method, a quantitive synthesis study is undertaken on the comprehensive benefits of reforestation. Performance criteria and evaluation model are referenced and suggestions for improving the performance of grain for green are put forward through the analysis of situation in reforestation area.The study has six chapters.Chapter One describes the background, the main objectives, basic ideas and logics.Content and special and novel aspects of the study.It also provides the latest information on the theoretical and practical studies of grain for green in China and other countries and makes comments on the theoretical studies regarding issues relevant to the subject of this study, and compares the special aspects of theoretical studies on reforestation at home and abroad.Chapter Two discusses the theoretical bases of investment effectiveness evaluation of reforestation by introducing the relevant theories in economics, ecology and land science firstly, then introduces the general situation of reforestation and defines the investment effectiveness and its frame.All these provide scientific and theoretical support for the studies on the investment effectiveness of reforestation.Chapter Three uses the data from statistics yearbook, contrast and analysis the investment scale and the structure of the public finance on the project,then analyses the problems which restrict the investment efficiency . Chapter Four analyses the cost and benefit of reforestation by using the method of cost and benefit and assesses the cost and benefit on different stake holders.Chapter Five adopts the AHP method in the formulation of criteria for investment effectiveness evaluation of reforestation and in the using of the math model for the synthesis evaluation.In this chapter, the reforestation area in ShanXi is taken as an example in the comparison of all the performance criteria before and after reforestation, thus concluding that a much greater comprehensive benefit can be achieved after the reforestation than before it.Chapter Six offers suggestions to improve investment efficiency of grain for green through harmonizing all relationships and relevant supportive system and raising funds by Multi-channel.This study has the following new approaches in its analysis:(1)Applies the AHP( analytic hierarchy process)method in the evaluation of investment effectiveness of grain for green,accoding to AHP's request and actual characteristic of grain for green,the investment effectiveness of grain for green can be definited as target hierarchy,criterion hierarchy and index hierarchy.This study attempts to construct reasonable evaluation system in method and content.It also aims to get reasonable result by using actual materials, and provides theory basis to the lasting development of reforestation.(2)In view of there is mostly fiscal investment in grain for green,and the low efficiency of fiscal investmen,with the actual implementation situation of grain for green,the author proposes to construct multi-investment system,guiding and encouraging folk investment to improve the investment effectiveness of grain for green.
