中文摘要：

本文以213家长三角上市制造业企业作为样本,实证分析了产业链定位、企业规模与集聚是如何影响企业核心竞争力的。研究结果表明：长三角的制造业在产业链的一些终端环节,并未能实现应有的强有力的核心竞争力;用固定资产衡量的企业规模与企业核心竞争力有着显著倒U型非线性关系,并推算出倒U的拐点为固定资产840亿,而长三角绝大多数企业没达到;集聚效应并未对长三角制造业企业核心竞争力产生积极影响。文章的最后给出决策思路。

英文摘要：

The paper makes an empirical research on how industrial chain positioning ,firm scale and agglomeration influence core competence of firms based on sample data of 213 listed manufacturers in the Yangtze River Delta. The research resuits show that the manufacturing sector in the Yangtze River Delta concentrates on end stages of the industrial chain and fails to realize strong core competence; firm scale measured by fixed assets and firm core competence have an obvious inverted U- shape non-linear relationship, and the point of inflexion of the U-shape lines is RMB84 billion fixed assets which is beyond most of the size of manufacturers in the Yangtze River Delta; agglomeration effect plays no positive role in core competence of manufacturers in the Yangtze River Delta. The final part of paper gives solutions.
