【摘要】：产业结构变动及其网络测度是区域可持续发展的基本领域,产业关联网络的形成与完善则是区域产业结构转型的主导目标,能够为相关经济现象的空间解析提供重要信息。通过应用1997年、2002年和2007年中国投入产出表,通过产业部门的合并,基于社会网络分析(SNA)构建了包含了网络密度、中心度、中介度、凝聚子群等指标在内的中国产业关联网络分析评价体系。研究结果表明中国区域产业关联网络密度由1997的年0.563上升到2007年的0.614,表明产业间经济联系程度逐渐加强,但进展缓慢;各产业中心度整体上呈现小幅度波动趋势,以金属冶炼及压延加工业为代表的第二产业呈明显上升趋势,是拉动经济增长的主要力量,并在空间上逐渐向东部和沿海地区集聚;化学工业、租赁和商务服务业、石油和天然气开采业等产业节点中介度呈现连续的较大上升,表明该类产业在整个产业网络中起到了重要的枢纽作用。1997年以农业为中心产业的凝聚子群对其本身的密度系数最大(5.880),2007年则演化为以石油和天然气开采业(2.264),表明产业子群经济联系在转换的同时其子群差异也在降低,产业间联系趋于均衡。研究成果在理论上探索构建将投入产出表与社会网络分析相集成的产业网络测度分析方法,同时在实践上为国家制定产业结构调整相关政策提供决策参考。
[Abstract]:The change of industrial structure and its network measurement are the basic fields of regional sustainable development, and the formation and improvement of industrial related network are the dominant targets of regional industrial structure transformation, which can provide important information for the spatial analysis of related economic phenomena. By applying the input-output tables of China in 1997, 2002 and 2007, and through the merger of industrial sectors, this paper constructs a network density, centrality, intermediation, which is based on social network analysis. The analysis and evaluation system of China's industrial association network, including the index of condensing subgroup. The results show that the density of regional industrial connection network in China increased from 0.563 in 1997 to 0.614 in 2007, indicating that the degree of economic connection between industries is gradually strengthened, but the progress is slow, and the overall industrial center shows a small fluctuation trend. The secondary industry, represented by the metal smelting and calender processing industries, shows a marked upward trend, is the main force driving economic growth, and gradually gathers spatially to the eastern and coastal areas; the chemical industry, leasing and business services, The degree of intermediation in industries such as oil and natural gas mining has increased significantly in a row. The result shows that this kind of industry plays an important pivotal role in the whole industrial network. In 1997, the agribusiness coacervation subgroup had the largest density coefficient of 5.880%, and in 2007 it evolved into oil and gas extraction industry 2.264%, indicating the production. At the same time, the economic relation of industrial subgroup is changing and the difference of its subgroup is also decreasing. The relationship between industries tends to be balanced. The research results theoretically explore the construction of an industrial network measurement and analysis method which integrates the input-output table and the social network analysis, and provides a decision reference for the country to formulate relevant policies for industrial structure adjustment in practice.
