城镇低效用地再开发政策对土地利用效益的影响研究——基于双重差分方法的验证
|
摘要
本文的研究目的为利用全国254个地级市2009-2016年面板数据,考察实施城镇低效用地再开发政策对城市土地利用效益的影响,并分区域、分类型对不同城市政策影响的差异性进行分析,以期为完善城镇低效用地再开发政策体系提供参考。通过双重差分法(Differences-in-Differences Method)和双向固定效应模型,得出研究结果为:(1)实施城镇低效用地再开发能明显提升城市土地效益,其能提升相应城市的地均GDP约4.36个百分点;(2)政策实施存在明显的阶段性效应,土地利用效益的提升作用在政策开展第3年最为显著;(3)城镇低效用地再开发政策效应存在异质性,东部城市土地效益提升最为明显,中部次之,西部则不显著,平原城市土地效益提升尤为显著,山地城市则不显著,此外,城镇低效用地再开发对重工业城市的土地效益提升作用也比较明显。得出的研究结论为政策制定应考虑不同地域、不同类型的城市基础情况,政策实施应注重阶段性效应,并对政策实施进行不断反馈与调整。
The purpose of this study is to provide a reference for improving the urbaninefficient land redevelopment policy system based on the analysis of the impact of urban inefficient land redevelopment on land use efficiencyand the heterogeneity of the influence, usingthe panel data of 254 cities in 2009-2016.Differences-in-Differences method and the two-way fixed-effects model were employed. The results show that:(1) the implementation of urban low-efficiency land redevelopment can significantly improve the urban land use efficiencyand the GDP of unit urban land increased by about 4.36%. The redevelopment of urban inefficient land has obvious phase effects.(2) The improvement ofland use efficiency is most significant in the third year of policy implementation, and the GDP of unit urban land is increased by about 7.20%.(3) The effect of urban inefficient land redevelopment policy is heterogeneous. The land use efficiencyin the eastern cities improved the most,followed by the central cities and the improvement of land use efficiencyin the western cities are not significant. The land use efficiency in plain cities has increased significantly, while that in mountainous cities are not significant.In addition, the re-development of inefficientland in urban areas is also more effective in improving the land use efficiency of heavy industrial cities. The research suggests that policy makers should consider the basic conditions of different regions and different types of cities. Policy implementation should pay attention to the phase effects and continuously feedback and adjust the implementation of policies.
