Results show: (1)The new energy automotive industry has a high-tech intensive degree, and the relationship between technological diversification and firm performance comes out an inverted U shaped curve; (2)The core technology competence plays a positive moderating role in the relationship between technology diversification and firm performance; (3)Marginal value of technology diversification on firm performance differentiates with the different value of core technology competence. These conclusions show that using technological diversification strategy should be based on a certain degree of firm-specific core technology competence, and then set up a linkage and coordination between technologies to promote the firm innovation performance simultaneously.
