An Interregional Computer Input-output Model Based on MRIO and Big Data Analysis

The input-output model of three provinces and two cities around Bohai Sea is constructed by using the interregional flow of goods and labor. This Model mainly adopts the Multiregional Input-Output Model (REFERRED to as MRIO Model) proposed by Chenery and Moses, through the definition of inter-regional trade coefficient, so as to obtain the data of product flow of each department between different regions. Leontief and Strout further proposed the gravity model to calculate the inter-regional trade coefficient matrix, and Ihara introduced the concept of transport volume distribution coefficient, which further simplified the data demand and calculation of the inter-regional input-output model. By Bohai sea provinces city regional input-output model, compared with Beijing, Tianjin, Hebei, Liaoning, Shandong five regional influence coefficient and sense degree coefficient, the results showed that the Bohai sea region industrial structure presents the obvious characteristics of heavy industrialization, especially is concentrated in the petrochemical, steel, equipment manufacturing, heavy industry and coal industry. Therefore, the difference of industrial structure between three provinces and two cities in Bohai rim region is not obvious.
