【摘要】：环境外部性一直是资源环境经济学的研究重点,已有研究大多以空间计量为手段实证研究环境污染的空间负外部性,而对环境保护的空间正外部性缺乏研究。以陕西省秦巴山区国家重点生态功能区县域生态环境指数为研究样本,采用空间计量模型,对生态环境质量提高的正的空间外部性及生态环境质量的影响因素进行实证分析。结果表明:各县生态环境质量间存在明显的空间溢出效应,相邻县的生态环境质量指数每提高1%,本县生态环境质量指数提高0.22%;在影响生态环境质量的因素中,国家重点生态功能区转移支付对生态环境质量具有正向促进作用,但这种促进作用相对有限;经济增长对生态环境质量则具有负面影响,且这种影响比较微弱。文章的政策含义是县级政府应联防联治以共同促进本地区整体生态环境质量的提高,而中央应完善重点生态功能区生态补偿政策和相关产业调整政策以更好保护重点生态功能区的生态环境。
[Abstract]:Environmental externality has always been the focus of the study of resource and environmental economics. Most of the previous studies have empirically studied the negative spatial externality of environmental pollution by means of spatial metrology, but lack of research on the spatial positive externality of environmental protection. Taking the ecological environment index of the state key ecological function area of Qinba Mountain region of Shaanxi Province as the research sample, the positive spatial externality of the improvement of ecological environment quality and the influencing factors of ecological environment quality are analyzed empirically by using the spatial measurement model. The results show that there are obvious spatial spillover effects among the ecological environment quality of each county. The ecological environment quality index of the neighboring counties increases by 0.22 for each improvement of the ecological environment quality index of the neighboring counties, and among the factors affecting the ecological environment quality, The transfer payment in the national key ecological function areas has a positive promoting effect on the ecological environment quality, but this promoting effect is relatively limited, while the economic growth has a negative effect on the ecological environment quality, and this effect is relatively weak. The policy implication of the article is that the county government should unite with defense to jointly promote the improvement of the overall ecological environment quality in the region. The central government should perfect the ecological compensation policy and the related industrial adjustment policy in order to better protect the ecological environment of the key ecological functional areas.
