| This thesis is based on the core concept of "agglomeration and growth", then extended to regional relationship of "competition and development". From the perspective of political and economic competition among northeastern countries, the thesis aims to explore the future cooperation and development space in this region. By analyzing the regional spatial distribution traits of Northeastern Asia through the path of regional development and cooperation from competition and disagreement to mutual benefit and win-win result, the thesis seeks to examine the existence of regional core, then clarity its central subordination structure. The thesis analyzes comparatively every Northeastern Asian countries’economic and trade situation by means of exploratory spatial data analysis, and it suggests that the differences among these countries are mainly attributed to their congenital and acquired divergences. In terms of empirical study, the thesis applies comparative advantage theory and similarity theory to respectively construct the "Trade Gravity Model", to proceed the panel data regression. The results show that the double model variables can only be fully explained under the condition of constant coefficient without individual influence because the "fixed value" feature of distance variable, we cannot construct a fixed effect model.Thus, we should apply "Distance Weighted" to construct the spatial lag model, spatial error model and geographically weighted regression model, and based on a comparative analysis to their cross-section data regression results, we should underscore their spatial differences, seek to their optimal fitting. The research shows that the core region of Northeastern Asia distributes in the central Bohai Sea and the Sea of Japan region, presenting a feature of "multi-core, non-equilibrium" with a strong economic complementarities among China, Japan and South Korea, but the "multiple sea-land segmentation" and "geopolitical division (North Korea)" in this region, which creates a competition "buffer zone" for these three countries, along with sophisticated political and historic issues among them, will make every Northeastern Asian countries remain antagonism in a long run, however, these countries can only reach agreement and realize regional integration by competition. In the end, by analyzing the characteristics of the economic development of Northeastern Asian countries and the questions of the developing economies’catching up with the advance countries and transformation, the thesis puts forwards several suggestions. |
