Abstract:The development of the information technology industry in China and ASEAN countries has its emphasis, but innovation focuses on attention. Based on the data of listed companies of the information technology industry in China and ASEAN representative countries from 2010 to 2017, the structural equation model, BP neural network, and improved CNN convolution neural network model is used to study respectively. It is found that the innovation environment, technological innovation, and knowledge management are. Simultaneously, technological innovation plays an intermediary role between knowledge management, innovation environment, and competitive advantage, and knowledge management plays an intermediary role between the innovation environment and competitive advantage. In the window period, China's information technology industry's overall competitive advantage shows an increasing trend. However, the general level is still low, so it is necessary to strengthen further the innovation environment and knowledge management Guidance and support. Further research shows that although the development of the information technology industry in China and ASEAN countries is still at a medium level, the development momentum is good. We should strengthen regional cooperation, promote the implementation of the "information Silk Road" strategy, and push forward the economic development of the China ASEAN Free Trade Area.
