农地非农化经济驱动机制的理论分析与实证研究

协调好经济发展和农地保护的矛盾是实现我国社会经济可持续发展战略的重要基础,而农地非农化又是这一矛盾的焦点,合理调控农地非农化需要掌握其驱动因素的作用机理,辨识主导因素。论文从影响土地资源部门配置的社会经济因素出发,构建了一个农地非农化经济驱动机制的理论分析框架,并应用1995～2001年省级数据进行实证分析。初步分析结果表明,人口增长、固定资产投资是农地非农化的主要推动因素;土地利用的比较效益和耕地资源禀赋是农地非农化的基础因素;地方政府的收益以及地方政府的管制应对行为与农地非农化呈正相关关系,而土地的市场化配置程度与农地非农化的面积呈负相关关系。根据上述的研究结果,文章提出了相应的政策建议。

Theoretical and Empirical Study on the Land Conversion Economic Driving Forces

Harmonizing the contradiction between economic growth and cultivated land conser-vation has important effect on the realization of sustainable development in China,and land conversion is the focus of that contradiction.In order to control land conversion rationally,we must understand the driving factors.In this paper we construct a theoretical framework of land conversion economic driving mechanism,and make an empirical analysis using the data of provincial level between 1995 and 2001.Results indicate that population increase and fixed assets investments are the major driving factors,land use comparative benefit and cultivated land endowment are the basic driving factors,land conversion income and the anti-governance behavior of local government has a positive relationship with the quantity of land conversion,but the development of land market and the comparative benefit of farmland has a negative relation-ship with the quantity of land conversion.As a result,some valuable propositions are presented.
