区域环境治理的府际合作网络研究——以关中地区雾霾联防联控为例

Network Analysis of Regional Environment Governance under Inter-Governmental Cooperation--An Example of the Joint Prevention and Control of Smog in Guanzhong Area

空气污染的负外部性和易反复性决定了单靠一市一区难以取得成效,跨域合作治理已成为共识,但合作网络主体间关系结构和动态演变过程的揭示仍显不足。文章对关中地区最近十年间雾霾联防联控的157项政策文本进行社会网络分析,通过网络密度、网络中心势、点度中心度、凝聚子群等指标的测量,探究关中地区雾霾合作治理网络的结构和演化特征。结果表明:关中地区雾霾合作治理网络已经形成,合作深化、拓展;西安始终处于合作网络中心,但各市区影响力趋于平衡;府际协作推动力纵向嵌入和横向协调并举,但以纵向嵌入为主。同时也要警惕行政权威主导失灵情形的发生,加强宣传沟通和横向协调,调动市场和社会力量。

Considering the negative externalities and repeatability of air pollution,cross-regional cooperative governance has become a consensus,but empirical research on the relationship between cooperative network agents is still insufficient. To explore the structure and evolution characteristics of regional cooperative network,157 policy texts in recent ten years were analyzed by using network density,network centralization,degree of centrality and aggregation subgroup. The study found that the network of haze cooperation in Guanzhong has been formed and more mature. Xi’an is always at the center of the cooperation network,but the influence of each urban area tends to balance.Top-down pressure and horizontal coordination work together to promote intergovernmental cooperation,but mainly the former. At the same time,we should also guard against the failure of administrative authority,strengthen communication and horizontal coordination,and mobilize market and social forces.
