绿色政绩考核对城市土地配置的影响研究——基于改进政绩考核的准自然实验

Study on the Impact of Green Performance Evaluation on Urban Land Allocation:A Quasi-natural Experiment Based on Improved Performance Evaluation

研究目的:从二三产业和细分行业两个层面,探究绿色政绩考核对城市土地配置的影响效果及其异质性。研究方法:双重差分模型。研究结果:(1)绿色政绩考核能缩小城市土地在工业与服务业间配置的规模与价格差异,且对规模差异的改善更为突出和持续;(2)绿色政绩考核可使商服用地规模增加,工业用地价格提高,但无法降低商服用地价格和工业用地规模;(3)对于污染密集型行业,绿色政绩考核下其用地价格明显提升,而清洁生产型行业用地规模显著增加;(4)绿色考核对高行政级别城市土地配置影响很小,且对土地价格影响不显著;对服务业主导型城市的影响小于工业主导型城市;对东部城市用地规模的影响大于中西部城市,对东部城市用地价格的影响小于中西部城市。研究结论:绿色政绩考核对城市土地配置具有积极影响,且依赖于行政级别、产业结构和所属区域呈现出城市异质性。为使城市土地资源配置最优,应坚持因地制宜改进绿色政绩考核标准,平衡政府管控和市场机制在土地配置中的作用效果。

The purpose of this study is to explore the impact of green performance evaluation on the allocation of urban land quantity and price and its heterogeneity from the secondary and tertiary industries level and the subdivide industries level.The method employed is DID estimation.The results show that.1)green performance evaluation can reduce the price difference and scale difference of urban land allocation,and the improvement in the scale difference is more prominent and sustained.2)Green performance evaluation can increase the land area used in the commercial service industry and increase the land price used in the industrial industry,but it cannot reduce the price of commercial service land and the scale of industrial land.3)For the pollution-intensive industries,land prices increase obviously under the green performance evaluation,while the area of land used by cleaner production industries increases significantly.4)Cities with high administrative level are minimally affected by green performance evaluation,especially in terms of land prices,which are almost unaffected.Both industry-and service-dominated cities are significantly affected,but the influence degree of the latter is less than the former.Cities in all regions are also significantly affected,but the eastern cities are more affected in area,and the central and western cities are more affected in price.In conclusion,green performance evaluation has a positive impact on urban land allocation,depending on city’s administrative levels,leading industries and regions,and presents urban heterogeneity.Meanwhile,administrative measures have limitations.In order to optimize the allocation of urban land resources,the performance evaluation standards should be improved according to local conditions,and the effect of government control and market mechanism in land allocation should be balanced as well.
