[Abstract]:Agricultural land resources are the most basic elements of agricultural production. It is an irreplaceable and non-renewable natural resource to provide necessary food and other means of production for the survival and development of human beings. At the same time, the farmland resources also have the ecological functions of protecting the environment, purifying the air, ensuring the national food security, providing employment, guaranteeing the peasants' life and other social functions. The decrease of farmland resources will inevitably reduce the value of its subsidiary economic function, ecological function and social function. In the process of economic development, countries all over the world have taken corresponding measures to protect high-quality agricultural land resources. The protection of agricultural land resources is regarded as an important issue related to economic development, social stability and ecological balance. The protection of agricultural land resources is a problem of efficient utilization and rational allocation of land resources. The essence of this problem is how to make the land resources can be used sustainably, how to improve the income of agricultural land resources management, and how to narrow the gap between agriculture and other industries. It is of great significance to study the efficiency of the protection mechanism of agricultural land resources for discovering the problems existing in the process of protection and utilization of agricultural land resources. China is in the stage of rapid economic transformation and urbanization. The trend of non-agricultural land resources in China is obvious. The protection of agricultural land resources is under great pressure. We must pay attention to and insist on the protection of agricultural land resources for a long time. Firstly, this paper studies the research progress of domestic and foreign scholars in the protection mechanism of farmland resources and the present situation of farmland resources protection in China. It is found that the theoretical research and the protection in practice are not enough, and the policy implementation is not in place. Has caused the farmland resources destruction, the land pollution and the land waste and so on question. Secondly, in the analysis of farmland resources protection mechanism of empirical research common methods, including Cobb-Douglas (C-D) production function method, conditional value evaluation method (CVM), On the basis of pressure-state-response (PSR) framework and data envelopment analysis method (DEA), this paper chooses the index system of pressure-state-response framework based on sustainable development. Considering the advantages of data Envelopment Analysis (DEA) in weakening the subjective influence and simplifying the data processing process, this paper chooses the data Envelopment Analysis Model as the empirical research model. The method of BCC model based on output-oriented variable scale reward is adopted. This paper takes the index data of 25 provinces as cross section sample data and the national data from 1993 to 2012 as time series data to analyze the efficiency of farmland resources protection mechanism in different provinces and different times, combined with Spearman correlation analysis. It is revealed that there is a positive correlation between the protection of agricultural land resources and the development of market economy: the more developed the market economy, the higher the efficiency of the protection mechanism of agricultural land resources, and the market mechanism is conducive to the protection of agricultural land resources. Finally, the paper puts forward some suggestions for improving the protection mechanism of agricultural land resources: setting up a comprehensive goal of the unity of equity and benefit in the protection of agricultural land resources, establishing a market mechanism for the protection of agricultural land resources, and making the market play a fundamental role in the allocation of land resources. We will improve the macro-control system for the protection of agricultural land resources, standardize government land expropriation, develop modern agriculture and manage on a moderate scale, and strengthen the construction of social security in rural areas.
