环境规制、引致性研发与企业全要素生产率 ――对“波特假说”的再检验
|
Abstract:
以中国规模以上工业企业数据为研究样本，分三个层次检验了“波特假说”的存在。首先运用Tobit模型检验了环境规制与企业研发之间的关系，在此基础上考察了由环境规制引致的研发对企业全要素生产率的影响，最后检验了环境规制对企业全要素生产率的影响。结果表明：环境规制促进了企业研发，而且这种由环境规制引致的企业研发显著促进了企业生产率的提升，对环境规制与企业生产率关系的检验进一步验证了“波特假说”的存在；另外，环境规制对企业研发的影响因污染强度和所有制不同存在明显差别。
We divide three sections to test the existence of Porter Hypothesis by using China′s industrial enterprises above designated size data.First, we test the relationship between environmental regulation and R&D by using Tobit model, and on this basis we calculate the induced R&D caused by environmental regulation, then analyze the effect caused by the induced R&D to the TFP.Finally, we test the influence of environmental regulation on TFP.The results show that environmental regulation promotes firms′ R&D, and this induced R&D significantly promotes firms′TFP, so the relationship between environmental and firms′ TFP confirmes the existence of Porter Hypothesis.In addition, the effect of environmental regulation on firms′ R&D varies with the firms′ pollution emission intensity and the firms′ ownership types
