中文摘要：

以昆山为例，对外商群体投资、外向配套与地方经济发展的关系进行了定性与定量分析。通过Granger因果检验和两个回归模型的对比分析发现，在一定程度上，外商群体投资是影响地方外向配套的原因，外商群体投资对地方经济的影响是通过外向配套来进行的。其政策含义是地方政府如果不能在外商群体投资与内资企业间建立一个有效的联系通道，则外商群体投资并不能有效地促进地方经济的发展。

Taking Kunshan as an example, this article examines the relationship among foreign group investment, export-oriented production linkage and local economic development with qualitative and quantitative methods. Employing granger causal examination and comparison between two linear regression models, this article finds out that to some extent foreign group investment is the cause of local export-oriented production linkage, and the former affects local economic development through the latter. Its implication for policy makers is that if local government cannot build an effective channel between foreign group investment and local firms, foreign group investment will not able to promote local economic development effectively.
