Abstract: Industrial green development is a key approach to urban pollution emission and energy consumption, and largely boosts its green sustainability. This paper, based on Zhejiang's 2000—2019 industrial economic panel data, uses Cobb-Douglas production function model to explore the impacts of environmental regulations intensity on Zhejiang's industrial green development, and divides Zhejiang into four areas ad two categories of urban sizes, and empirically studies the heterogenous effects ofenvironmental regulations intensity on industrial green development. Environmental regulations intensity largely decreases Zhejiang's unit energic consumption, outstandingly boosting its industrial green development, but the impacts vary, better in western and southern Zhejiang than in eastern and northern. Environmental regulations intensity improves their industrial green development in cities with variable populations, better in middle-small cities than in large cities in reducing unit energic consumption. Environmental regulations can still largely decrease unit GDP energic consumption after removal of model's endogenous issues, verifying the stability of model. The overall marketization level plays a key role in decreasing the unit regional GDP energic consumption by environmental regulations intensity, and marketized environmental regulations also reduce Zhejiang's overall unit regional GDP energic consumption. This paper presents suggestions for Zhejiang to make appropriate environmental regulations intensity in order to push industrial green development and quality economic growth.

摘要： 在新时代发展背景下，工业绿色发展是解决城市污染排放和能源消耗的重要路径，对促进城市工业绿色可持续发展起重要作用。本文利用2000—2019年浙江省各地区的工业经济面板数据，基于柯布-道格拉斯生产函数模型探究环境规制强度对浙江省工业绿色发展的影响，按照官方地区划分方式将浙江省进一步分为4个地区和2种城市规模，实证考察环境规制强度对工业绿色发展的异质性效应。实证结果表明：1)环境规制强度显著降低了浙江各地的单位能耗，对浙江工业绿色发展具有显著促进作用；2）异质性分析发现，环境规制强度对浙江省各地区工业绿色发展的影响存在差异。其中，环境规制强度对浙江西部和南部地区单位生产总值能耗的降低效果最为明显，但对浙江东部和北部的影响不显著；3）环境规制强度对不同人口规模的城市均有促进工业绿色发展的影响，且降低中小城市单位能耗的效果要比降低大城市单位能耗的效果更明显；4）在消除模型内生性问题后环境规制强度依然可以显著降低浙江各地区单位生产总值能耗，验证了模型的稳健性；5）影响机制检验结果表明，市场化整体水平在环境规制强度降低单位地区生产总值能耗的过程中发挥显著影响，市场化环境规制工具对降低浙江整体单位地区生产总值能耗起到重要作用。本文为制定合理的环境规制强度以推动工业绿色发展和经济高质量增长提供了经验证据和政策启示。
