政策冲击如何影响石化和化学工业绿色转型?——来自准自然实验的证据

How Does Policy Affect the Green Transformation of Petrochemical and Chemical Industry?——Evidence from Quasi-natural Experiments

以我国2016年《石化和化学工业发展规划(2016—2020年)》出台为准自然实验,运用双重差分法考察选择性产业发展政策对企业绿色转型的影响。实证结果显示:与非石化化工企业相比,这一政策冲击促使石化化工企业绿色转型的效果更好,而且与选择性产业政策要通过政府直接干预手段发挥作用的经济直觉一致。基于地区视角的分组检验显示,金融监管强度和政府干预力度对转型过程均起到正向促进作用。进一步研究表明,产业政策的出台一方面通过增加投入产出端的资源配置在增效层面促进石化化工企业全要素生产率水平的提高,另一方面通过限制石化化工企业的资金获得在减排层面降低企业污染排放,从而实现企业绿色转型。

The paper takes China′s Petrochemical and Chemical Industry Development Plan(2016—2020)issued in 2016 as a quasi-natural experiment,and uses the difference-in-differences method to examine the impact of selective industrial development policies on the green transformation of enterprises.The empirical results show that compared with non-petrochemical chemical enterprises,this policy shock has a better effect on promoting the green transformation of petrochemical chemical enterprises,and it is consistent with the economic intuition that selective industrial policies should play a role through direct government intervention.The grouping test based on the regional perspective shows that the intensity of financial supervision and government intervention play a positive role in promoting the transformation process.Further research shows that the introduction of industrial policies,on the one hand,promotes the improvement of total factor productivity of petrochemical and chemical enterprises by increasing the allocation of resources at the input-output end,and on the other hand,reduces the pollution emission of enterprises at the emission reduction level by limiting the capital acquisition of petrochemical and chemical enterprises,so as to realize the green transformation of enterprises.
