Abstract: Due to its special spatial organizational form, industrial cluster is convenient to accumulate social capital, which plays a key role to the promotion of innovation performance.But the characteristics of the dimensions of industrial cluster’s social capital is not the same under different life cycle stages. Few people study whether the impact on innovation performance exists a big gap because of the difference.This article is based on this view to carry on a thorough discussion to provide reference for the industrial cluster in different life cycle stages to improve innovation performance.The empirical results show: in the formative years, only vertical social capital is significantly positively related to innovation performance; in the growth period, all the vertical social capital、horizontal social capita and the sideling social capita are significantly positively related to innovation performance and the correlation is the most obvious;In mature stage,horizontal social capital and innovation performance shows negative correlation, vertical and sideling social capita are still significantly positively related to innovation performance, but the correlation weakens.

Key words: industrial cluster, cluster social capital, life cycle, innovation performance
