The System Dynamic Analysis Of Synergistic Support Of Fiscal And Finance For New-type Urbanization In Less-developed Areas

Since the 18^th CPC National Congress,new-type urbanization with transformation as the main line,not unilaterally puts emphasis on simple agglomeration of urban population and blind expansion of towns,but pays more attention to the effective allocation,optimization and upgrading of elements such as population,capital,industry and so on.Essence of people-oriented,quality as the key,rich in content and complex in structure,new-type of urbanization is to achieve the coordination of social,economic and ecological development simultaneously.There is an obvious gap between developed areas and less-developed areas.Currently,the process of urbanization in less-developed areas is lagged far behind,which has greatly hindered the overall development of the region.Fiscal,together with finance owns unique advantages and complements each other in fund supply,industrial upgrading,economic growth and some other aspects,which can just solve the problem of inadequate investment in less-developed areas.Thus,probing into the complex synergy mechanism of fiscal and finance,based on the characteristics of urbanization in less-developed areas,may contribute to realizing the result of1+1>2.It is of great practical significance.Urbanization in less-developed areas can't be separated from fiscal policy and funding support,but also thirsty for finance and private capital as supplement.Aimed at strengthening the synergistic effect of fiscal and finance,the thesis assimilates characteristics of complex systems such as feedback,dynamics,nonlinearity and time lag into the subsystem of new-type urbanization and the synergy subsystem of fiscal and finance in less-developed areas.From the perspective of system dynamics,the paper explores mainly in four aspects as follows:relevant theoretical basis,synergy mechanism analysis,SD model construction and simulation,and policy suggestion.Firstly,theoretical groundwork:analyzing the connotation of new-type urbanization and the characteristics of less-developed areas,in dimensions of society,economy and ecology;sorting out the synergy principle between fiscal and finance in economic society;introducing the system dynamics theory and analyzing whether it's applicable for the research object of this paper.Secondly,mechanism analysis:focusing on the mechanism of how fiscal and finance coordinate in promoting new-type urbanization based on synergy theory.Synergy in social-urbanization is explained as investment from fiscal in dominant,together with finance system funding for the government or private capital participating.Synergy in economic-urbanization is described as supporting agriculture and small-and-medium enterprises by fiscal direct investment or finance capital guided by fiscal policy-information feedback.Synergy in ecological-urbanization is illustrated as achieving ecological balance by fiscal regulating.Thirdly,SD model construction:based on the connotation and mechanism,the paper makes the causal relationship diagram and flow chat from the aspects of urbanization,fiscal,finance and synergy between fiscal and finance,which describe the internal feedback mechanism visually and provide the parameters for the simulation equation.Fourthly,test and simulation:after the historical test,the paper changes some parameters to make simulation by Vensim PLE.It shows that the fiscal plays the most important role in the development of urbanization in less-developed areas,while finance is insignificant.Lastly,policy suggestion:with the propulsion of theoretical analysis and the evolution of SD model,the paper puts forward policy-making suggestion from the aspects of widening the resources of fiscal capital,improving the environment of finance investment and strengthening the fiscal guidance to promote the synergy between fiscal and finance,in order to optimize the development of urbanization in less-developed areas.
