RESEARCH ON THE CAPACITY OF INDUSTRIAL LINKAGE CHANGES IN HENAN
利用影响力系数、感应度系数和部门产出占比构建扩散能力指数和感应能力指数，分析1987-2007年河南省产业部门间内在联系的变化趋势，发现传统和资源密集型产业仍是主导，基础能源产业影响增强，生产性服务业和高技术产业虽滞后但增长明显。
The trend of the industrial linkage changes is an important indicator which reflects the changes of the internal economic links between national economic sectors, and recognizing the trajectory of the industrial linkage changes will make important sense to the formulation of industry restructuring policies. With the overlay of the influence coefficient, the sensitivity coefficient and the proportion of sector output, we build spreading capability index and sensing capability index, and analyze the trend how the intrinsic link between industrial sectors in Henan Province changes with the two indices and the input-output table of Henan Province 1987-2007. It’s found that the traditional industries sector and resource-intensive industries are main sectors of Henan Province with accumulated growth from the year 1987 to 2007, we can not completely abandon the dominant traditional industries sector and resource-intensive industry while promoting industrial restructuring; meanwhile, the influence and restriction that basic energy industry have on the economic development of Henan Province have been gradually increasing; production services and high-tech industries have lagged behind, but there are obvious growth trend.
