摘要
从协同治理长江中游城市群雾霾污染的角度出发,选取1998—2015年地级及以上城市雾霾污染的面板数据,基于莫兰指数、Getis-Ord指数G、STIRPAT和空间滞后SAR模型对雾霾污染的污染路径、时空演变特征、空间溢出效应及影响因素进行讨论。研究发现:1998—2015年长江中游城市群雾霾污染总体呈现波动变化趋势,其地理梯度分布大致为"江淮城市群>武汉城市圈>总体平均>环长株潭城市群>环鄱阳湖城市群";雾霾污染在地理空间上呈现出显著的正相关性且以武汉市和合肥市为中心表现为"热点"聚集区域,以南昌市和萍乡市为中心表现为"冷点"聚集区域;雾霾污染表现出显著的时间依赖特征和空间溢出效应,工业集聚和城镇化是显著加剧雾霾污染的重要原因,而经济聚集和人口集聚则显著降低了雾霾污染。最后,政府和企业应当从调整研发投入比例,加快建立跨区域协同治理雾霾污染的体制机制等途径降低雾霾污染带来的不良影响。
Based on the panel data of haze pollution in cities at prefecture level and above from 1998 to 2015,the pollution path,spatial and temporal evolution characteristics,spatial spillover effect and influencing factors of haze pollution are discussed based on Moran index,Getis-Ord index G,STIRPAT and space lag SAR models.The results are as follows.The haze pollution in the middle reaches of the Yangtze River from 1998 to 2015 shows a fluctuating trend,and its geographic gradient distribution is roughly"Jianghuai City Group>Wuhan City Circle>Overall Average>ChangZhu-Tan City Group>Poyang Lake City Group".Haze pollution showed a significant positive correlation in geographic space,with Wuhan and Hefei as the center for the"hot spot"gathering area,Nanchang and Pingxiang as the center for the"cold spot"gathering area.The haze pollution shows significant time-dependent characteristics and spatial spillover effects.Industrial agglomeration and urbanization are the main reasons for the significant aggravation of haze pollution,while economic agglomeration and population agglomeration significantly reduce haze pollution.Finally,the government and enterprises should adjust the proportion of R&D investment,speed up the establishment of a cross-regional cooperative system to reduce the adverse effects of haze pollution.
