非正式环境规制能否推动工业企业研发

当面对环境治理与工业发展这一难题时，非正式环境规制给出了新解决路径。利用2007-2016年中国内地30个省市面板数据，在区分研发投入与研发成果的基础上，采用门槛面板模型研究非正式环境规制与工业企业研发间的非线性关系。结果表明，非正式环境规制对工业企业研发投入和研发成果的单一门槛效应成立。此外，非正式环境规制对于研发投入和研发成果的作用还受工业企业现金流和经营效率的影响。研究非正式环境规制对研发投入的影响发现，现金流存在单一门槛，经营效率则存在双重门槛；研究非正式环境规制对研发成果的影响发现，现金流和经营效率均存在单一门槛。

Whether Informal Environmental Regulation Can Promote Industrial Enterprise R&D

In the face of environmental governance and industrial development,informal environmental regulation has opened up a new path.Based on the panel data of 30 provinces and cities from 2007 to 2016,informal regulation,cash flow and operating efficiency were selected as threshold variables on the basis of distinguishing R&D input from R&D outputs.The non-linear relationship between informal regulation and industrial R&D was studied with the threshold panel model.The results show that informal regulation on input and achievement of industrial R&D has a single threshold effect.The effect of informal environmental regulation on R&D input and R&D results is also affected by the cash flow and operating efficiency of industrial enterprises.When researching the impact of informal environmental regulations on R&D investment,there is a single threshold for cash flow and a double threshold for operating efficiency.There is a single threshold for cash flow and operating efficiency When researching the impact of informal environmental regulations on R&D results.
