【摘要】 以江浙沪地区为研究对象,根据2002年、2007年和2012年江浙沪地区投入产出表,采用社会网络分析法,从水资源投入产出视角构建江浙沪地区产业关联网络,计算特征途径长度、聚类系数、网络中心性、凝聚子群等相关网络特征指标,对江浙沪地区总体及其中各省市的产业关联进行比较分析。结果显示,江浙沪地区产业关联网络具有小世界性,网络密度较高,产业关联程度较为密切;以化学工业为代表的工业部门中心性非常突出,是地区的中心产业,服务业部门地位有所上升,但产业部门发展非均衡性也更加突出;目前形成8个凝聚子群,凝聚子群内的产业部门之间关联度相对较高,发展呈集群化趋势。提出优先对中心产业节约集约用水、提高水资源循环利用率、制定差异化水资源政策、推进产业融合等建议,旨在为江浙沪地区产业在水资源约束条件下实现均衡可持续发展提供参考。更多还原

【Abstract】 According to the input-output tables of JiangsuZhejiang-Shanghai area in 2002,2007 and 2012, using the social network analysis its industrial linkage network is formulated from the perspective of water resource input-output.The relevant indices such as characteristic path length,clustering coefficient, centrality and cohesive subgroup are calculated, and the industrial linkages in the total JiangsuZhejiang-Shanghai area and various provinces and city are compared and analyzed. The results show that there is a smallworld property and high network density with close industrial linkage. The chemical industry representing the industrial sector is of outstanding centrality and is the central industry in the area,and the status of service sector has increased, but the disproportion is even more prominent. Now eight cohesive subgroups are formed,and the linkage between their industrial sectors,which indicates the trend of development is clustering.Some suggestions are put forward in order to promote the balanced and sustainable development under water resource constraints,such as saving and using water intensively on central industry, improving the utilization of water resources,formulating different policies on water resources and promoting industry integration.更多还原
