摘要
打破市场分割、畅通要素流动是建设全国统一大市场、构建高水平社会主义市场经济体制的前提和基础,也是建设美丽中国、推动生态环境治理体系和治理能力现代化的支撑和保障。本文以长三角地区为例,运用价格法测度市场分割指数,并从时序变化、数据结构和状态判别等角度进行分析。进一步,将市场分割与生态环境纳入统一分析框架,运用空间计量经济学方法探讨市场分割对空气污染的影响机制,并进行多维度实证分析和检验。研究发现:(1)从时序演变上看,长三角地区以及各省、市均不同程度地存在市场分割问题,但总体呈现波动下降的趋势。(2)从数据结构上看,市场分割指数中心位置相对稳定、分布范围相对集中,但一定程度上存在由离群值引起的偏态和尾重。(3)从状态判别上看,市场分割状态随商品和城市的不同而表现出多样化特征,但并未表现出明显的省域或地域差异。(4)从模型检验上看,市场分割会显著提升空气污染水平,对环境质量产生负面影响。此外,市场分割会通过抑制生产要素流动、阻碍产业结构升级和科学技术进步影响空气污染。(5)对于全国统一大市场的建设无法也不能一蹴而就,需要分区域、分步骤的长期谋划和渐进式推进。在推进长三角市场一体化发展的基础上逐步实现全国统一大市场建设是次序合理、操作可行的路径。在市场一体化建设的过程中,注重构建、培育和完善多层次生态要素协调互动的市场合作机制,为落实“两山理论”和践行“两山经济”奠定坚实的市场基础。
Breaking market segmentation and unimpeded factor flow are the prerequisite and foundation for building a national unified big market and constructing a high-level socialist market eco⁃nomic system,as well as the support and guarantee for building a beautiful China and promoting the modernization of ecological and environmental gov⁃ernance system and governance capacity.Taking the Yangtze River Delta region as an example,this article applies the price method to measure the market segmentation index and analyzes it from the perspectives of time series change,data structure and state discrimination.Further,market segmen⁃tation and ecological environment are incorporated into a unified analytical framework,and spatial econometric methods are applied to explore the impact mechanism of market segmentation on air pollution,and multi-dimensional empirical analysis and tests are conducted.The study finds that:(1)From the point of view of time-series evolution,market segmentation exists to varying degrees in the Yangtze River Delta region as well as in all prov⁃inces and cities,but the overall trend is fluctuating and decreasing.(2)From the perspective of data structure,the center position of market segmentation index is relatively stable and the distribution range is relatively concentrated,but to some extent,there are skewness and tail weight caused by outliers.(3)In terms of state discrimination,the market segmentation state shows diversified characteristics with different commodities and cities,but does not show obvious provincial or geographical differences.(4)From the model test,market segmentation sig⁃nificantly enhances the level of air pollution and negatively affects environmental quality.In addition,market segmentation affects air pollution by inhibiting the flow of production factors,hindering industrial structure upgrading,and scientific and technological progress.(5)The construction of a unified national market cannot and will not be accomplished over⁃night,but requires long-term planning and gradual advancement in a regional and step-by-step manner.Gradually realizing the construction of a national unified market on the basis of promoting the integrated development of the Yangtze River Delta market is a reasonable and feasible path.In the process of market integration,emphasis will be placed on building,cultivating and perfecting a market cooperation mechanism for the coordination and interaction of multi-level ecological factors,so as to lay a solid market foundation for the imple⁃mentation of the‘Two Mountains Theory’and the practice of the‘Two Mountains Economy’.
