| 摘 要： | 论文以产业集聚的环境外部性为切入点,利用中国1999-2012年的省级面板数据实证分析了产业集聚水平、产业集聚与技术创新的关联效应对环境污染的影响,并进一步将样本分为沿海省份和内陆省份,检验了产业集聚影响环境污染的区域差异。研究结果表明,产业集聚与环境污染呈倒"U"型关系,而技术创新在决定"拐点"的位置上发挥了关键作用;全国绝大部分省份均位于倒"U"型曲线的左侧,即产业集聚水平尚未跨越门槛值而发挥环境正外部性,其中沿海省份比内陆省份位于左侧曲线的更高位置,意味着较高的集聚水平对应了更强的环境污染,但沿海省份技术创新的减排效应小于内陆省份,表明沿海省份的集聚正外部性正在减弱,其集聚发展已进入瓶颈期。

Empirical research on the relationship of industrial agglomeration,technological innovation and environmental pollution |
| |
| Abstract: | Based on the perspective of environmental externality of industrial agglomeration, this paper uses the panel data of China’s provinces from 1999 to 2012 and analyzes how industrial agglomeration, the linkage of industrial agglomeration and technological innovation impact on environmental pollution. Furthermore, we divide the sample into two groups, coastal provinces and inland provinces, then examine if there exists regional disparity. The results show that: (1) The relationship between agglomeration and pollution is inverted-U-shaped and technological innovation acting as an important factor determines the location of the turning point. (2) Almost all of the provinces locate on the left side of the inverted-U-shaped curve, which means China’s industrial agglomeration has not possessed a positive environmental externality. (3) Coastal provinces achieve a higher position on the curve than inland provinces, which means coastal provinces with higher level of industrial agglomeration as well as more pollution. However, the emission abatement induced by technological innovation of inland provinces is much more significant than coastal provinces, which means that the positive externality of industrial agglomeration of coastal provinces is decreasing and that its development of agglomeration has entered a bottleneck period. |
