Abstract:Based on the analysis framework of energy transition in power industry innovation network,this paper defines the network density,the network scale and the small world within the Social Network-Complex System from four aspects of institution,economics,technology as well as behavior,and puts forward three hypotheses for the energy transition path evolution.Based on the data of power industry innovation network from 2010 to 2019,this paper uses time series analysis methods,such as ADF test,co-integration test and error correction model,to study path dependence and path breakthrough of China’s energy transition.The results show that the existing network density of technological innovation consolidates the path dependence of China’s power industry.The current network scale of the power industry innovation in China can play an important role in promoting the path breakthrough,but the Small World is hindering the path breakthrough to some degree.At least for now,the technological innovation in China is seriously out of touch with China’s energy transition,which fails to live up to the expectations of the Chinese Government.
