Abstract: When examining the impact mechanism of technological progress on the new international specialization, not only must the geographical heterogeneity characteristics be taken into full consideration, but also the inherent heterogeneity characteristics of the industry and the impact of external financial storms.This paper combines the idea of gravity model and applies general equilibrium theory model to bring geographic heterogeneity, technological progress and bilateral trade into the same research framework.While considering the geographical heterogeneity, we will focus on the differences between the impact of technological progress on the new and traditional international specialization. Further, the high-dimensional fixed-effect Poisson pseudo-maximum likelihood estimation (PPML-HDFE) method was used to select panel data from 18 industries in 43 countries and regions from 2000 to 2014 to study geographic heterogeneity, technological progress, and inner relationship.The possible heterogeneity characteristics of the three internal relationships are discussed by industry and time period. The empirical results are basically consistent with the theoretical model assumptions.There are two aspects of policy guiding significance in this study: First, the determinants of the new international division of labor are clarified, and further insight into the changing rules of the new international division of labor.Second, from the perspective of the new international division of labor, it provides experience and important inspiration for improving "China's trade dilemma."
