Abstract：
While the expending product variety model of endogenous growth theory are now common, empirical application lags far behind. The fundamental reason is that the core of the model variables, the statistical measurement of product varieties has not been satisfactorily resolved. The authors proposed the product variety measurement method based on Chinese product variety index in Chinese technological innovation statistical formation, applied the two methods of product variety measurement to measure Chinese product variety, and made an empirical study of Chinese economic growth according to the result of the mearurement. The initial conclusion is as follows: (1) the limitation of trade variety index based on trade data lies in data availability. If the data problem is solved, the method can be used widely in the researches into preference and earnings; (2) the Chinese product variety index based on significant technological innovation statistical formation is feasible. The the key question is how to define product meaning; (3) the results of the empirical researches into Chinese endogenous growth show that there is a positive relationship between Chinese product variety and productivity according to the estimate of the two measurement methods, which support the hypothesis of endogenous growth.
