环境目标约束下的产业高质量发展研究

Research on Industrial High-quality Development Under the Constraint of Environmental Goals

在运用熵值法构建产业高质量发展指数的基础上,本文使用2003—2021年的地级市面板数据,采用双重差分法识别环境目标约束对产业高质量发展的作用。研究发现,环境目标约束对产业高质量发展具有显著促进作用,这一结论在平行趋势检验、排除相关政策干扰、使用同一个省内地级市数量和河流密度作为工具变量进行内生性分析等稳健性检验后仍然成立。机制分析发现,环境目标约束下,环境规制的增强和财政科研支出的增加推动了产业高质量发展。进一步进行异质性分析发现,环境目标约束主要对东部和西部城市的产业高质量发展具有显著正向影响。本研究为产业高质量发展及其相关政策制定提供了支持和参考。

Based on the evaluation of industrial high-quality development using entropy method,this paper uses the panel data from 2003 to 2021 and DID method to identify the influence of constraint of environmental goals on industrial high-quality development.It shows that constraint of environmental goals can enhance industrial high-quality develop-ment.This conclusion is still robust after parallel trend test,excluding the interference of relevant policies,and using prefecture level city number in the same province and river density as instrumental variables for endogenous analysis.Mechanism analysis shows that constraint of environmental goals can promote industrial high-quality development by strengthening environmental regulation and increasing fiscal research expenditure.Further heterogeneity analysis shows that constraint of environmental goals mainly promotes industrial high-quality development of eastern and western cities.It provides support and reference for industrial high-quality development and formulation of related policies.
