Abstract: The technological environment for industrial development includes two parts. One is the external environment which usually includes the variation rate of technology and heterogeneity of technological capabilities, and the other is the internal environment that is typically represented by technological capabilities. Based on the three factors explained as dimensionalities, a method is developed to evaluate the industrial technological characteristics and, according to them, different industries are clustered to frame and analyze the technology innovation strategy for enterprises. Thus, the theoretical basis and methodology of analysis are provided for enterprises to predict the technological development, analyze technological environment and selecting technological innovation strategy. An empirical analysis is made for 12 main industries in equipment manufacture in Liaoning Province.
