Non-Linear Input-Output Model And Its Application In Regional Economy

It experienced a number of regional development issues in our country because in the past several decades we emphasis on economic benefits, the reasonableness of the price in the economic sector of region is one of the issues. The price of certain sectors in the region is not accord with the economic development, so the analysis of the reasonableness of the price in the regional economy is very necessary. Using mathematic model to do research on economic problems both on theory and reality becomes the key indicator of economic developing to modern science. Wide application of input-output technology in economic field since it has been generated as it is a kind of number economic analysis method. In this paper, reasonable price issues have been studied by the input and output method.We introduce Input-output analysis related theories firstly in this paper, and describe the theory of the Non-linear input-output model, the price theory and the theory of regional economic model in summary.Secondly, we discuss the major revision method of direct consumption coefficient, including expert survey, RAS method, major elements reversion method, Markov method, ect. And developed the two steps RAS method based on the traditional RAS method.Then, we pay more attention on doing research on reasonable price using Non-linear input-output model. We calculated the reasonable prices of the ten sectors products according the data from Input-output extension table of Hebei province in 2005 and Hebei Economic Statistics Yearbook (2001-2005) by the model. There was no real estate bubble in Hebei Province in 2005 according to the analysis of the real estate industry. The real estate prices is actually slightly lower, should rise about 13% .We use the calculated results to do the analysis on real estate industry of the ten departments products in the last of the paper, and indicate that there is no bubble phenomenon in real estate industry of Hebei province.
