The economic growth accounting of China's provinces between 1990 and 2004 finds some results like the following: no matter whether human capital was introduced or not, there were technological inefficiencies in most provinces'economic activity which were pure technological inefficiencies or scale technological inefficiencies; technological change, capital deepening and human capital accumulating all promoted labor productivity, but technological efficiency change played a negative role during these years as a whole; the descending order of provincial difference of labor productivities'changes brought out by each factor was technological change, capital deepening, technological efficiency change and human capital accumulating; each province's pure technological efficiency change or scale efficiency change not only had different size, but also different evolution route.

中国各省在1990～2004年间的经济增长核算结果表明：不论是否引入人力资本，大多数省份的经济活动都存在着技术无效率，这既包括纯技术无效率，也包括规模无效率；技术进步、资本深化和人力资本积累都促进了劳动生产率的提高，而技术效率的变化整体上来说在其中起阻碍作用；各因子引致的劳动生产率变化的省际差异从大到小依次为技术进步、资本深化、技术效率的变化和人力资本积累；各省的纯技术效率或规模效率的变化不仅大小不同，而且它们的演变路径也不一样。
