长江经济带雾霾污染的省域异质性与空间溢出效应研究

发布时间:2018-09-17 10:16
【摘要】:“依托黄金水道,建设长江经济带”在2014年《政府工作报告》中明确指出,标志着建设长江经济带上升为国家战略。十八届五中全会中,“创新、协调、绿色、开放、共享”五大发展理念的提出,明确指出了长江经济带发展方向。然而,日益严重的雾霾污染对这一区域的生态安全、公共健康、国际形象等方面形成重要挑战,随着长江经济带雾霾污染态势日益严峻,如何突破雾霾污染所形成的发展瓶颈,成为全社会高度关注和普遍忧虑的问题。雾霾污染问题的出现也绝非是个别区域造成,而是出于成片集中的聚集效应,这也说明了雾霾污染问题具有很强的空间依赖性。那么,这种空间依赖性多大程度影响着雾霾污染?是否存在着某个经济拐点,当跨越了该点之后雾霾污染呈现出显著性突变?为此,着力研究长江经济带雾霾污染的省域异质性与空间溢出效应,在雾霾污染治理目标下研究长江经济带绿色经济增长的路径和对策,这对缓解和治理长江经济带雾霾污染,优化产业结构和空间布局具有决策参考价值,对长江经济带践行创新、协调、绿色、开放、共享的发展理念具有示范意义。本文以长江经济带雾霾污染的异质性和空间溢出效应为研究目标,结合2000-2012年长江经济带省际面板数据,一方面从空间相关性出发,结合经济对环境的“倒U型”假说理论,建立空间杜宾模型,探讨经济增长对长江经济带雾霾污染的空间溢出效应,验证倒U型假说的是否成立;另一方面从异质性角度出发,建立面板门槛回归模型,讨论在不同门槛变量影响下,经济增长与雾霾污染之间的非线性关系,分析研究长江经济带不同省市雾霾污染的经济拐点。研究结果表明,一方面长江经济带雾霾污染省域间存在显著的空间溢出效应,经济增长对雾霾污染亦存在显著的空间溢出效应;另一方面在不同影响因素的作用下,人均GDP对长江经济带雾霾的污染均具有显著的单门槛特征,且当人均GDP和工业增加值作为门槛变量时,经济增长在门槛变量跨越门槛值后对环境负效应有所放缓,当在不同人口聚集和对外开放程度下,经济增长对雾霾污染程度出现明显的加剧。最后,立足于长江经济带发展的现实条件,提出长江经济带雾霾治理与绿色经济增长的方向和出路,从而为政府决策提供参考。
[Abstract]:"relying on the golden waterway, building the Yangtze River Economic Belt" clearly pointed out in the 2014 "Government work report", marked the construction of the Yangtze River Economic Belt as a national strategy. In the Fifth Plenary session of the 18th CPC Central Committee, the five development concepts of "innovation, coordination, green, opening and sharing" were put forward, and the development direction of the Yangtze economic belt was clearly pointed out. However, the increasingly serious haze pollution poses an important challenge to the ecological security, public health and international image of the region. With the increasingly serious situation of haze pollution in the Yangtze River Economic Zone, how to break through the development bottleneck caused by haze pollution. It has become a problem of great concern and general concern for the whole society. The problem of haze pollution is not caused by individual regions, but by the concentrated aggregation effect, which indicates that the haze pollution problem has a strong spatial dependence. So to what extent does this spatial dependency affect haze pollution? Is there an economic inflection point across which haze pollution mutates significantly? Therefore, this paper studies the provincial heterogeneity and spatial spillover effect of haze pollution in the Yangtze Economic Belt, and studies the path and countermeasures of green economic growth in the Yangtze Economic Belt under the goal of haze pollution control, which can alleviate and control the haze pollution in the Yangtze Economic Belt. The optimization of industrial structure and spatial layout is of reference value for decision making, which is of great significance to the practice of innovation, coordination, green, openness and sharing in the Yangtze economic belt. This paper aims at the heterogeneity and spatial spillover effect of haze pollution in the Yangtze economic belt, combining with the inter-provincial panel data of the Yangtze economic belt from 2000 to 2012, on the one hand, starting from the spatial correlation, combining with the theory of "inverted U-shaped" hypothesis of economy to the environment. The spatial Doberman model is established to explore the spatial spillover effect of economic growth on haze pollution in the Yangtze economic belt, and to verify the validity of the inverted U type hypothesis. On the other hand, from the perspective of heterogeneity, a panel threshold regression model is established. The nonlinear relationship between economic growth and haze pollution under the influence of different threshold variables is discussed. The economic inflection points of haze pollution in different provinces and cities of the Yangtze River economic belt are analyzed and studied. The results show that, on the one hand, there are significant spatial spillover effects among haze pollution provinces in the Yangtze economic belt, and there are also significant spatial spillover effects on haze pollution caused by economic growth; on the other hand, under the influence of different factors, Per capita GDP has significant single threshold characteristics for haze pollution in the Yangtze economic belt, and when per capita GDP and industrial added value are taken as threshold variables, the negative effects of economic growth on the environment after threshold variables cross the threshold are slowed down. Under the condition of different population concentration and opening to the outside world, the degree of haze pollution caused by economic growth increased obviously. Finally, based on the realistic conditions of the development of the Yangtze River Economic Belt, this paper puts forward the direction and the way out of the haze governance and the green economic growth in the Yangtze Economic Belt, thus providing a reference for the government to make decisions.
