基于DID模型的佛山市南海区农村集体经营性建设用地入市绩效分析

Performance Analysis of Rural Collective operational Construction Land Entering Market in Nanhai District of Foshan City Based on Differences-in-Differences Model

【目的】研究集体经营性建设用地入市政策对佛山市南海区带来的影响。2014年拟定的农村集体经营性建设用地入市改革试点取得了一定成效,盘活了农村土地资源,增加了农村集体经济,提升了农民收入。【方法】运用超效率DEA模型测算1995—2001年、2012—2018年的集体经营性建设用地市场效率,采用双重差分模型分析佛山市南海区试点政策实施前后的集体经营性建设用地入市绩效差异。【结果】2015年集体经营性建设用地试点政策实施后,2017年集体经营性建设用地利用效率比2015年提高0.78,反映集体经营性建设用地入市试点改革促进农村集体经营性建设用地入市预期的提高;农村居民收入对集体经营性建设用地利用率具有正向影响,在5%水平上显著;农业总产值和耕地面积均对集体经营性建设用地利用率具有负向影响,分别在5%和1%水平上显著。【结论】农村集体经营性建设用地入市政策试点区应当与当地实际情况相结合探索新的方式方法;“打通”改革试点的壁垒,增进改革试点协同合作力。

【Objective】The study is carried out to explore the impact of collective operational construction land market entry policy on Nanhai District of Foshan City.In 2014,the pilot reform of rural collective operational construction land entering the market has achieved certain results,which revitalized the rural land resources,increased the rural collective economy and improved the farmers’incomes.【Method】The super-efficiency DEA model was used to measure the market efficiency of collective construction land from 1995 to 2001 and 2012 to 2018.Then,the Difference-in-Differences(DID)model was used to analyze the performance differences in the collective operational construction land market entry before and after the implementation of the pilot policy in Nanhai of Foshan City.【Result】After the implementation of the pilot policy of collective operational construction land in 2015,the utilization efficiency of collective operational construction land in 2017 was 0.78%higher than that in 2015,indicating that the pilot reform of collective operational construction land market entry promoted the improvement of the expectation of rural collective operational construction land entering the market.The incomes of rural residents had a positive impact on the utilization efficiency of collective operational construction land,which were significant at 5%level.The total agricultural output value and cultivated land area had negative impacts on the utilization efficiency of collective construction land,which were significant at levels of 5%and 1%,respectively.【Conclusion】Policy pilot areas should be combined with the local actual situation to explore new ways and methods;We should“break through”the barriers of reform pilot and enhance the cooperation of reform pilot.
