Study On Economic Compensation Of Cultivated Land Protection Based On The Externality Theory

As to the survival of humans cultivated land resources, on the one hand, combined with human labor, and provide mankind production and living material, produce economic benefits; On the other hand still load the meet the demand of industrialization and urbanization land, to ensure the national food security, farmers’ basic necessities and ecological construction of returning farmland to forest grassland requirements etc. Function. But the cultivated land per capita quantity is little and diminishing resources shortage and quality has deteriorated, and in the future society in the process of economic development, the limited arable land resources are under growing pressure.Our country in the world adhere to the strictest arable land protection system, will the cultivated land protection as a basic state policy,but the existing cultivated land protection effect and anticipated goal is still quite a distance.Many factors influence the cultivated land loss, multi-function spillover effect of cultivated land protection is the key reasons.The existing land use system failed to sufficient to cover the cultivated land protection responsibilities and duties of the fair equivalence, an externality of cultivated land protection more and more prominent. In the cultivated land protection operation, all over the country also had a positive to try and exploration, and construct the cultivated land protection of economic compensation mechanism, to realize the internalization of externality of cultivated land protection, to achieve the purpose of cultivated land protection, has become an important topic of the cultivated land protection.This thesis includes eight chapters.Chapter 1:The cultivated land protection mainly is from the urgency and internalization of the background of externality of need, to carry out the research purpose, this paper discusses the significance, to determine the basic framework of research on the ideas and, using comprehensive methods, to regulate empirical method and the method of combining multidisciplinary research.Chapter 2:Mainly to the cultivated land protection at home and abroad, for cultivated land protection externalities, externality economic compensation and progress in the research dynamic comb and induced, and this paper to provide some reference for the research of. And fusion of the externality theory, the theory of public goods, land value theory and the sustainable development theory, this study provides support for the theory.Chapter3:Reconstruction of cultivated land use efficiency system, to determine the meaning of cultivated land externality, and taking Changshou district for example, studies the externalities of cultivated land conversion driver from the point of view of cultivated land resource valueChapter4:Measuring external benefits of cultivated land after the above definition of externality meaning. First, the hypothesis in study area has no externalities spillover sex, compared to a variety of academic measuring method, choose equivalent of ecological factor method service benefit estimates, by using the substitution resume cost method to the national food security benefits and social security benefit estimates. And with longevity area as an example, the calculated result shows that cultivated land for social provide large amounts of external benefit, this be a farm subsidies a big reason, also become the calculation amount of a basis for subsidiesChapter5:This chapter specific area according to different level of cultivated land area and quality of comprehensive grain production ability level to determine the compensation standard economic externalities, get economic compensation standard of the theoretical value. Because of the cultivated land protection external benefit is a dynamic, the concept of development, according to the area social economic development level of theoretical fixed, get external benefit compensation standard reality valueChapter6:Defining the cultivated land protection main body, divided protection main body type, and the main body behavior analysis, then determining the cultivated land protection of economic compensation subject and object.Chapter7:From the point of view of the coordinate system, the construction of the economic compensation of cultivated land protection theory model, and to longevity area as an example, the compensation of subjects and objects, determine compensation standard, the compensation methods, system environment and so on constructing the cultivated land protection economic compensation mechanism.Chapter8:Summing up,in the external benefit to define, measure, and on the basis of constructing compensation mechanism, to realize the internalization of external benefits, inhibit non-agriculturalization of farmland, achieve the goal of cultivated land protection. At the same time for the shortcomings of the research is discussed...
