摘要
引入一种测度制造业同构的新方法,测度了1982～2003年长三角制造业的同构度。同时,依据产业组织理论中测度集中度的方法计算了相同时段内长三角制造业的集中度,对长三角制造业同构度与集中度的关系进行了分析,结果表明,二者存在着明显的负相关关系。
A structural superposition index that can measure the degree of same structure of manufacturing was introduced.The degree of same structure of manufacturing and the degree of concentration of manufacturing in delta area of the Yangtze river were calculated from 1982 to 2003.Their correlations were analyzed and the results showed that the degree of same structure of manufacturing have remarkable negative correlation with the degree of concentration of manufacturing in delta area of the Yangtze river.
