The results show that: (1) under the synergistic effect, intellectual capital has "single threshold "effect on business performance, and venture capital shareholding can be used as the judgment of venture capital and intellectual capital synergetic condition; (2) when the proportion of venture capital is higher than the threshold value, the intellectual capital would accelerate the market value and asset utilization efficiency of enterprises, but this phenomenon in the human capital value-added efficiency aspect of enterprises performance is not ideal. The results indicate that the value-added role of intellectual capital still has room to improve, but the synergistic effect needs conditions, which objectively requires entrepreneurial companies introduce venture capital targetedly, so as to reform, enhance and make use of the intellectual capital.
