摘　　要：产品种类扩大型内生增长模型的核心变量产品种数的统计测度一直没有得到很好的解决,是该理论相关经验研究进展迟缓的根本原因。笔者提出基于中国技术创新统计编制中国产品种类指数的产品种类测度方法,应用了两种产品种类测度方法对中国产品种类（1978~2008）进行统计测度;并根据测度结果对中国经济增长进行了实证研究。初步结论为：（1）基于贸易数据的贸易种类指数的局限性在于数据可得性,如果能解决数据上的困难,该方法可广泛应用于有关偏好和收益问题的研究中;（2）基于重大技术创新统计编制中国产品种类指数是可行的,但关键问题是产品含义的界定;（3）中国内生增长实证研究结果表明,两种测度方法估计的中国产品种类与生产率之间具有显著的正相关,支持内生增长假说。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.
