The Dynamic Factors of Guangdongs Economic Growth from the Perspective of Supplyside Reform Reexamining the overall economic situation and the industrial structure of Guangdong Province, the current subdistricts in Guangdong have insufficient development in supply and demand management, effectiveness review, factordriven and elimination of uncertain factors, and urgently need to scientifically and rationally define regional management dilemmas. Through the introduction of the CobbDauglas production function model, the total factor productivity of 21 districts in Guangdong Province are calculated. Concerned about the supplyside management elements and constant indicators of benefit in specific regions, efforts are made to promote Guangdong Province. The transformation of the economic and dynamic mechanism and the adjustment of its contribution rate are expected to effectively analyze the innovative path of economic development in Guangdong Province.

System DynamicsBased Simulation of Ecommerce Industry of Ethnic Regions in China As the national strategic emerging industry, ecommerce industry is attracting more attentions. In order to deeply understand the dynamic mechanism of the Ecommerce industry development, this paper divides the ecommerce industry development system into four interrelated subsystems on the basis of system dynamics: technological progress, market demand, economic development and industrial environment. We construct the dynamic model of the Ecommerce industry system using MATLAB software, which is guided by the government, technological progress, logistics level. The market demand is variable to design different simulation policies. The corresponding countermeasures and suggestions are also discussed for the development of the ecommerce industry in ethnic regions in China.
