创新集聚空间分布模式对霾污染的影响

为了比较分析创新集聚空间分布单中心与多中心两种模式对霾污染的影响机制，本文构建了省域面板数据模型和中介效应模型进行实证检验.结果表明：创新集聚可通过规模效应降低霾污染；但创新集聚空间分布模式对霾污染的影响具有异质性.其中，单中心模式诱发了霾污染，存在创新集聚环境效应悖论；多中心模式对霾污染具有改善效应；随着创新集聚多中心的提高，其霾污染改善效应增强，但具有边际递减特征；能源利用效率是创新集聚空间分布模式影响霾污染的重要渠道之一.基于此，本文建议省级政府推进空间协同创新发展战略，建构省域多中心的创新网络空间组织体系，以此形成多中心协同治霾机制，破解创新集聚环境效应悖论.

The impact of innovative agglomeration spatial distribution modes on haze pollution

In order to compare and analyze the influencing mechanism of monocentricity and polycentriciy distribution patterns on haze pollution, a provincial panel data model and an intermediary effect model were constructed for empirical test. The results showed that the innovation agglomeration reduced haze pollution through scale effects, however, the impact of innovative agglomeration spatial distribution modes on haze pollution was heterogeneous. Specifically, the monocentricity mode induced haze pollution, and there was an paradox of the environmental effect of innovation agglomeration. However, the polycentricity mode had an improvement effect on haze pollution. With the increase of the polycentricity of innovation agglomeration, its effect on haze reduction was enhanced, but with marginal diminishing characteristics. Energy utilization efficiency was one of the important channels for the spatial distribution modes of innovation agglomeration exerting influences on the haze pollution. Based on the findings above, this paper suggested that the provincial polycentric collaborative innovation development strategy was needed to be implemented, and the provincial polycentric innovation network organization system was imperative to be constructed by government, so as to form a polycentric synergistically governance mechanism for haze pollution, and to solve the paradox of environmental effect of innovation agglomeration.
