摘　　要：通过理论分析,假定该种影响是倒U型的,即一定程度的相关性集聚会因为加速关联产业间知识外溢,而过多的相关性集聚则会增加区域遭受经济冲击而停滞的可能。以此为依据构建解析模型,以1998～2013年中国226个地级以上城市为样本,选用个体固定效应模型,运用非参数协方差矩阵估计方法进行经验分析。验证了理论模型,即区域产业集聚相关性经济对经济产出的影响为倒U型。根据结论,对不同类型的城市给出相应的优化方向。Through theoretical analysis, this paper assumes that the effect of the relevant agglomeration mode on economic output is inverted U. Namely, a certain degree of relevant agglomeration will accelerate the knowledge spillover between the relevant industries. Too much relevant agglomeration will make the regional economy fall into path dependence and increase the possibility of regional economic stagnationsuffered from economic shocks. On this basis, it constructs the analytical mod- el, takes China 226 prefecture level cities from 1998 to 2003 years as a sample, selects individual fixed effects model and uses nonparametric covariance matrix estimation method for the empirical analysis. Results verify the hypothesis of the theoretical model, that is, the impact of the relevant industrial agglomeration on economic output is ＂inverted U＂. According to the conclusion, the corresponding optimization directions are given for different types of cities.
