【摘要】：文章基于DEA-SBM模型,测度了节能减排约束下工业行业的环境技术效率,检验了环境技术效率的收敛性和门槛效应。结果表明,我国工业行业环境技术效率总体偏低,但大多数行业环境技术效率都有不断提高的趋势,存在向环境技术前沿的追赶效应。引领环境生产前沿的创新者始终是高新技术产业和清洁产业,今后的结构调整应重点扶持与发展技术含量高的产业和清洁产业。收敛性检验结果表明,低排放行业既存在绝对收敛又存在条件收敛,具有俱乐部收敛特征;全部行业和高排放行业不存在绝对收敛,但存在条件收敛,说明环境政策及扶持力度需要向高排放行业倾斜。环境规制强度与环境技术效率之间存在非线性的三重门槛特征,且对于不同行业作用有别,环境规制政策的制定应避免陷入盲目提高环境规制强度的误区。
[Abstract]:Based on the DEA-SBM model, this paper measures the environmental technical efficiency of the industrial industry under the constraint of energy saving and emission reduction, and tests the convergence and threshold effect of the environmental technical efficiency. The results show that the environmental technical efficiency of China's industrial industry is on the low side, but the environmental technical efficiency of most industries has a trend of continuous improvement, and there is a catch-up effect towards the frontier of environmental technology. The innovators leading the leading edge of environmental production are high and new technology industry and clean industry all the time. In the future structural adjustment should focus on supporting and developing high technology content industries and clean industries. The results of convergence test show that there is both absolute convergence and conditional convergence in low emission industries, which has the characteristics of club convergence, and there is no absolute convergence but conditional convergence in all industries and high emission industries. It shows that environmental policy and support should be inclined to high emission industry. There is a nonlinear triple threshold between the intensity of environmental regulation and the efficiency of environmental technology, and the function of environmental regulation is different for different industries. Therefore, the formulation of environmental regulation policy should avoid falling into the misunderstanding of blindly increasing the intensity of environmental regulation.
