A Analysis Of Handan Economy Development Based On A Medium Or Longterm Econimic Models

National economy of anyone country can be descripted as a system composed of productive sectors and consumptive sectors which are of different qualities but interrelated one another.The production of any a sector needed the products of other sector as its input materials, and products of this sector can even be decomposed into final consumptive demand and inpmaterials need by another productive sectors. Hence, an universal dependent relation existed among various sectors, so the higher the economy developed in a country and the higher the degree of socialization of production and the more detailed of the classification of sectors, the closer the dependence of mutual relation between sectors. It is extraordinarily meaningful to apply input-output analysis oh studying the general correlation among these sectors for whether comparing economic structure of actual economic life, forecasting economic status and working out plan, or promoting the development of economic theory itself.Input-output table world be taken as a veritable bridge connecting theory and facts and would filled the "empty box" of economic theory and fully explained the mutual dependence of economic activities of intricate quantities. It is an important tool of analysis rather than a method of displaying and storag-ing data and materials. Also, it can be obtained as a basic method for analyzing and studying the economic development structure, according to the results in comparison of the input-output structures among the developed and the undevelopedcountries.Input-output technology would be used to establish input-output models to analyses the structure of sectors within an industry, to forecast how many final use shall be provided from each sector when the gross production of each sector of national economy was set, and to calculate and find out the quantity of gross output necessarily provided by each sector to satisfy the demand when a certain quantity of final use of each sector was demanded by whole society.This paper talks about some theories and their application in Chinese macro-econimic analysis and prediction based on input-output model which is studied now.Chapter 2 introduces the analysis and relevant contents about the input-output models, eg its formation, development and the update study on it; about several theoretical questions on the input-output accounts; about it' s role in our system of national accounts.In chapter 5, The RCS and modified RCS methods for directly updating the value based Leontief inverse are proposed. And then the implied relationship between them with the conventional RAS method is discussed. Subsequently the RCS and modified RCS methods are compared with the indirect RAS method via an example. It is demonstrated that the methods we introduce, especially the modified RCS method is more practical than the indirect RAS method. RAS Methods is the important instrument of updating input coefficient. In order to find comparatively reliable information embedded updated input coefficient, this paper establishes evaluation criteria of reliability of RAS methods with which the accuracy of inhomogeneous input coefficients are compared at the base of constant-dolla rtables for 1992 and 1997 in China.
