旅游产业集聚对环境污染的差异性影响:287个地级市例证

The Differential Impact of Tourism Industrial Agglomeration on Environmental Pollution: Empirical Evidence from 287 Cities

产业集聚的环境外部性问题是业内研究热点,不同形式的产业集聚对于环境污染的影响机制存在差异。基于旅游产业集聚视角,利用2010～2016年我国287个地级市面板数据与空间面板计量模型实证探究旅游产业集聚对环境污染的影响。研究结果表明:从全国视角来看,旅游产业集聚与环境污染呈现倒"U"型关系,其拐点处的旅游产业集聚水平为0.884,绝大多数地级市旅游产业集聚能够对环境污染的改善起到一定促进作用,技术创新与产业结构优化在旅游产业集聚影响环境污染中发挥了重要的渠道作用;从区域视角来看,东部、东北与西部地区旅游产业集聚对环境污染改善具有显著的正向影响,而中部地区旅游产业集聚对环境污染的改善效果并不显著。

The environmental externality of industrial agglomeration is the hotspot of research in the industry,and different forms of industrial agglomeration have different impact mechanisms on environmental pollution.Based on the perspective of agglomeration of tourism industry,this paper carries on the empirical study of the impact of tourism industrial agglomeration on environmental pollution through panel data of 287 cities in China from 2010 to 2016 and spatial panel econometric model.The results show that:from the national perspective,the relationship between tourism industrial agglomeration and environmental pollution is inverted-U-shaped and the agglomeration level of tourism industry at inflection point is 0.884.The agglomeration of tourism industry in most cities can effectively relieve environmental pollution,and technological innovation and optimization of industrial structure have played important roles in the impact of agglomeration of tourism industry on environmental pollution.From the regional perspective,agglomeration of tourism industry in eastern,northeast and western regions both significantly reduce environmental pollution,while agglomeration of tourism industry in the central region has no significant effect on environmental pollution.
