环境规制对省域绿色创新效率的门槛效应研究

A Study on the Threshold Effect of Environmental Regulation to Provincial Green Innovation Efficiency

文章通过省域环境成本最优规划探讨正式、非正式环境规制影响绿色创新的机理,选取2005-2014年各省域面板数据为研究样本,利用Super-SBM模型测算绿色创新效率,在此基础上构建门槛回归模型实证检验正式、非正式环境规制对绿色创新效率的门槛效应。结果表明:正式环境规制与绿色创新效率之间存在单门槛值,两者之间呈"U"型关系,非正式环境规制与绿色创新效率之间存在单门槛值,两者之间呈倒"U"型关系,交通设施条件,居民素质程度、劳动力投入和资本投入与绿色创新效率均存在显著正相关关系。

Through the provincial environmental cost optimal planning, this paper discussed the mechanism of formal and informal environmental regulation affecting green innovation and selected provincial panel data in 2005 -2014 for the study sample, used Super - SBMmodel to calculate the green innovation efficiency. And then constructed threshold regression model to test the threshold effect of formal and informal environmental regulation on green innovation efficiency. The results showed that there is a single threshold value between formal environmental regulation and green innovation efficiency, and a ＂U＂ relationship between the two; there is a single threshold value between informal environmental regulation and green innovation efficiency, and a inverted ＂U＂ type relationship between the two; Traffic facilities, residents＇ quality, labor input and capital input had significant positive correlation with green innovation efficiency.
