文摘A new concept of“legal infrastructure”has recently been emerging and becoming increasingly popular in China.The concept offers a novel analytical framework to explore China’s existing legal organism for creativity.For this academic mission,the perspective of venture capital is developed by this article in that it has been already been convincingly demonstrated by extant studies that venture capital is an indispensable catalyst for the output level of a country’s creativity.The findings of this article are that the current legal infrastructure in China impedes the life cycle of venture capital,to some degree,and in turn impairs the capability of creativity in China’s economy.
