According to the standard neoclassical model of trade theory, technology and factor endowments are both important determinants of specialization. This paper attempts to investigate the industrial specialization in China determined by both of the sources of comparative advantage. Using a 30 provinces, 9 years panel of China’s manufacturing industrial data and seemingly unrelated regression (SUR) technique, we find that the effect of relative technology differences is quite large and significant during the recent years. Factor endowments differences also have effects on the output share, but the results are inexplicit and elusive in some industries.
