摘要
利用1997—2015年的地级市数据,借助双重差分方法和空间计量模型,以SO_2排放量的对数值为衡量指标,对"两控区"政策的效果进行了实证检验。结果表明,"两控区"政策的实施使区内城市的SO_2排放量减少了23.4%,整体来看政策效果较为显著;然而,分区域的检验却发现政策效果在不同地区存在着明显差异。同时,利用空间计量分析,发现地方政府竞争是阻碍环境质量改善和削弱环境规制政策效果的重要因素。因此,环境政策应从区域管理转向全域管理,从行政规制逐步转向经济手段与行政、法律手段相结合,同时,应通过促进地方政府的合作与协调,抑制地区间过度竞争,更好地促进环境质量的改善和环境政策目标的实现。
Based on the prefecture-level data from 1997-2015,this paper used the methods of difference-in-difference(DID) and the spatial econometric model to evaluate the effect of TCZ policy,with the logarithm of SO2 emissions as the indicator.The results suggested that the implementation of TCZ policy made SO2 emissions decrease 23.4% in TCZ compared with cities out of TCZ,which was significant on the whole.However,separate tests of different regions found significantly distinct impacts of this policy,meanwhile the results of spatial econometric model suggested local government competition is an important factor hindering the improvement of environmental quality and weakening the effectiveness of environmental regulation policies.Therefore,environmental policies should shift from regional management to overall management,from administrative regulation to the combination of economic,administrative and legal means.At the same time,the central government should motivate the cooperation and coordination of local governments and restrain excessive competition among regions so as to improve the environmental quality and achieve environmental policy goals.
