On the basis of previous studies, this paper analyzes the relationship between technological diversification and technological convergence, arguing that technological convergence is a performance of inverse technological diversification, and pointing out that technological innovation is the alternating process of technological diversification and technological convergence. On this basis, the paper presents an empirical method of technological convergence analysis, and combines with the existing methods by analyzing the characteristics of technological diversification and inter-industrial technological convergence in Chinese high-tech areas from different perspectives. From the perspective of technological areas, the order of diversification from high to low is ICT technology, fuel cell technology, nuclear energy technology, biotechnology and environment-related technology. From another perspective of purpose of technology, the order of diversification is biotechnology, fuel cells technology, environment related technologies, ICT technology and nuclear energy technologies. In technological convergence analysis, Chinese high-tech technologies do not have the σ technological convergence, but have β technological convergence, the speed towards the steady-state level is 2.4%. In the analysis of inter-industrial technological convergence, H05K in ICT field, A61P and C07H in biotechnology field, B32B, H02J, C02F and C07C in fuel cell field demonstrate inter-industrial convergence phenomenon.
