Establishment Of Interregional Input-Output Table Of The Yangtze River And The Three Effects

At first,This paper developed the interregional input-output table by means of non-investigative methods.The interregional input-output table contains four regions in 2012,these sectors are Shanghai,Jiangsu,Zhejiang and other parts of the country.Inter-regional merchandise trade flows are estimated from the gravitational model.Inter-regional trade flows of goods mainly use the data in "2013 China Transportation Yearbook".The main source of data for the input-output table is the input-output table for the country and the various sectors in 2012.According to the multi-regional input-output model,the input-output table of the Yangtze River Delta 42 is compiled.In the measurement method,the Miller-Round model is expanded to establish a three-region model,and then calculate the multiplier effect,spillover effect and feedback effect of economic growth in the Yangtze River Delta region.When compiling the input-output table,use the RSA adjustment method to adjust the inter-regional mobile trade flow.In this paper,multi-regional input-output structure decomposition technology is used to measure the multiplier effect,spillover effect and feedback effect.Finally,the three-zone model is used to analyze the input-output table.Calculate the multiplier effect in the region,the interregional spillover effect,the interregional feedback effect of the overall and sub-sector of the Yangtze River Delta,to analyze the economic relations between the three places as well as the industrial level.From the interregional spillover effect,it is found that,Zhejiang has the greatest spillover effect on Shanghai,and the total spillover effect of Jiangsu to Zhejiang is the smallest in the sum of the spillover effects of other regions in each region.This shows that Zhejiang's leading role in the Shanghai region,Jiangsu's leading role in the weakest in Zhejiang.In addition,this paper also studies the related characteristics of the Yangtze River Delta industry from different industrial effect values,and puts forward specific suggestions for promoting the coordinated development of industry in Yangtze River Delta from reality.
