From 9th to 11th in January, at the invitation of business school, Professor An Husen, who comes from Institute of Economics of Nankai University, China's famous expert in the field of Spatial Economics research, came to our school to give lectures for Economics Ph.D. Students and postgraduates about the relevant knowledge on regional economic growth and structural transformation in Room 106 of Xingmin Building.
Firstly, Professor An HuSen explained the essence of regional economy: Regional economics focused on the changes between regions caused by the regional transfer of factors of production. Traditional classical economics is based on the assumption of constant or diminishing scale and complete competition, which can not explain the formation of urban areas and other practical problems, which called the Spatial Impossible Theorem. In order to explain such issues, regional economics came into being. Subsequently, Professor Anhu Sen took the development of Spatial Economics as the axis, respectively interpreting various model theories about the Regional economic growth and structural transformation, from three aspects: the Neoclassical growth theory, new economic geography, space-time economic development .
When it comes to the classical theory of growth, Professor analyzed three typical models closely to explain the spatial economics: Hoyt model that focuses on demand outside the region (output base model)、The Harold-Thomas model that focuses on the supply outside the region, and the Botswana model that focuses on the optimal allocation of production factors in the region. From the aspect of new economic geography, Professor An Husen started from the D-S framework (monopolistic competition model) to analyze consumer behavior and producer behavior, revealing the relationship between diversity of consumer demand and increasing returns to scale, and monopolistic competition. Then he introduced Krugman's classic core-periphery (CP) model of Spatial Economics, analyzed the market agglomeration and decentralization from the market proximity effect, cost of living effect and market competition effect, and then gradually explained how the spatial economics incorporated the concept of space into the traditional general equilibrium analysis. In view of the perspective of space economic development , Professor An explained improvement of the technological level and regional economic development in the time dimension, the transformation and upgrading of the regional economic structure in spatial dimensions. He believed that regional economic growth and the evolution of regional structure were two aspects of regional development. Regional economic growth was the expansion of productive capacity and economic scale. The evolution of regional structure was the replacement between the new and old economic structure. On this basis, Teacher An led a detailed deduction and explanation of the classical models of spatial economics such as the free capital (FC) model, the capital creation (CC) model, the global spillover (GS) model and the local spillover (LS) model .
Professor An Husen explained the basic theories and models of regional economic growth and structural transformation in simple terms. All students benefit a lot and it greatly stimulated the enthusiasm and initiative of everyone to learn and apply the knowledge of spatial economics.
