The Optimization Model Of The Economic Structure And Applied Research Based On Extension Technique Of Input-Output

"Accelerating transformation of the mode of economic development, and creating a new situation of scientific development", It is clear request of the Fifth Plenary Session of the Seventeenth Central Committee of CPC. For a country or area, we are not only pay attention to the quantity of economic development, but also the quality of economic development more should be emphasized on the economic development road, to strive for economic efficient development, it is key step to realize the change of economic development mode. How to achieve economic health, steady development in two dimensions of quantity and quality, economic structure optimization problem studies will appear extremely urgent, this paper writing has theoretical significance and practical significance of dual value.Based on the compare of economic structure optimization theory at home and abroad, the author thinks that the input-output technology has outstanding advantages in analyzing the relationship between industry and industry, so, first based on input-output extended technology, the author construct nonlinear dynamic input-occupation-output model and economic structure optimization model, and theoretical analysis the model's application value; Secondly, in order to verify the model's actual application value, a case studying of Hebei province, basis of Hebei province four years (2000,2002,2005,2007) input-output table, combined with other relevant data, the author detailed empirical analysis Hebei's current economic structure and the future economic development. Thirdly, after the calculation of the actual model, give some the corresponding auxiliary calculation, which not only forecast Hebei province current and future economic, but also give various kinds of economic structural relationships, such as relationship between input-output, relationship between fixed assets investment and workforce investment, relationship of three final demand, etc, and given the optimal growth speed and best industrial structure. Finally, through study, the conclusion provide scientific countermeasures and suggestions for industry optimization of Hebei 12th Five-year Plan, provide reference for the kinds of industries'investment and development in the next few years, and also lay a foundation for changing economic development way of Hebei province.This paper mainly has four innovation:one is constructing the nonlinear dynamic input-occupation-output extended model, this model is expansion of nonlinear dynamic input-output model, fixed asset investment and occupation, workforce investment and occupation, three final demand are included in the model, the objective wants to make the model have more advantage on analyzing structure of economic; Two is basis of Hebei province four years (2000,2002,2005,2007) input-output table, according to the division of science, the author divide three industries of Hebei into 18 departments of industries, through rearrange data, get four years new input-output table of Hebei province, so as to facilitate empirical analysis. Three is the other relevant auxiliary calculation based on the mode! and economic structure optimization model, such as fixed assets investment contribution, workforce investment contribution, and so on. Four is using the model and based on this model constructed economic structure optimization model to empirical analysis Hebei's economic development, provide scientific countermeasures and suggestions for industry optimization development.
