环境规制对云南省产业结构升级的影响

IMPACT OF ENVIRONMENTAL REGULATIONS ON UPGRADING INDUSTRIAL STRUCTURE IN YUNNAN PROVINCE

环境规制对产业结构转型升级、经济增长和环境保护均具有重要的影响。论文聚焦环境规制作用于产业结构的机理,以云南省16个地州市作为研究样本,利用面板数据构建计量模型,实证检验环境规制对产业结构升级的影响。结果表明:1)云南省环境规制强度与技术创新之间存在倒"U"型关系,当前环境规制强度小于拐点值6.46,环境规制强度的提高能推动技术创新水平的提高;2)云南省环境规制强度与产业结构升级之间存在正"U"型关系,当前环境规制强度小于拐点值5.20,应不断提高环境规制强度使其跨过拐点以促进云南省产业结构升级;3)环境规制和消费结构、投资结构、利用外资水平之间均为正相关关系,而产业结构升级与消费结构、投资结构、利用外资水平之间均为负相关关系,即环境规制无法通过改善消费和投资结构来促进产业结构升级。因此建议要不断提高环境规制强度,并对中小企业给予适当的补贴,督促地方政府执行环境规制政策,促进产业结构升级。

Environmental regulations play a vital role on upgrading or transforming industrial structure, economic growth and environmental protection. This paper discusses the mechanism of environmental regulations on industrial structure, and uses panel data to establish a counting model to check the impacts of environmental regulations on upgrading industrial structure based on 16 cities in Yunnan province. Yunnan’s environmental regulation intensity has a upside-down "U-shaped" relation with technical innovation, which means technical innovation level can be improved if environmental regulation intensity is less than 6.46, and has a positive "U-shaped" relation with industrial structure upgrading in which increasing environmental regulation intensity may promote industrial structure upgrading if the environmental regulation intensity continues to increase beyond the inflection point value of 5.20. Consumption structure, investment structure and foreign use level are positive to environmental regulation, but negative to industrial structure upgrading, indicating that environmental regulation can not boost industrial structure upgrading by improving consumption and investment structure. This paper presents suggestions on promoting industrial structure upgrading from increasing environmental regulation intensity, distributing allowance to small and medium-sized companies and enforcement of environmental regulations.
