摘要
受环境规制的影响,区域政策对不同类型企业生产率的提升具有一定异质性。本文以西部大开发政策作为准自然实验,使用三重差分(DDD)方法和"无条件分布特征—参数对应"方法,重点考察该政策对不同污染程度企业生产率的异质性效应。研究发现,西部地区环境规制较为宽松,西部大开发对当地高污染类型企业的生产率提升较大,对其他企业生产率的改善效果不佳。进一步探究其生产效率提升路径,区分集聚效应和选择效应回归分析发现,西部地区所有行业相对集聚优势都有所上升,但高污染行业提升幅度更大,已形成显著优势;同时,高污染行业在西部区域的选择效应较小,甚至存在吸引较低效率企业进入的倾向。本文的研究为区域政策精准落地实施提供了有益参考。
Regional policies have heterogeneouseffects on the productivity of different types of firmsdue to environmental regulations.In this paper,weuse the Western Development Policy as a quasinatural experiment and focus on the heterogeneouseffects of the policy on the productivity of firms withdifferent pollution levels using DDD and the‘uncon-ditional distribution characteristics-parameter corre-spondence’method.The study finds that the westernregion has a more relaxed environmental regulation,and the productivity of local enterprises with high pol-lution level is improved more by the Western Devel-opment Policy,while the productivity of other en-terprises is not improved as well.Further exploringits productivity enhancement path,the regressionanalysis distinguishes between agglomeration effectand selection effect and finds that the relative ag-glomeration advantage of all industries in the westernregion has increased,but the high pollution industryhas increased more and has formed a significant ad-vantage;meanwhile,the selection effect of high pol-lution industry in the western region is smaller andeven has the tendency to attract less efficient enter-prises to enter.The research of the paper provides auseful reference for the precise implementation ofregional policies.
