Research On The Correlation Effect Of China Railway Transportation Industry

The railway transportation industry is the main artery of China’s national economic development and promotes the development of the national economy.In recent years,the rapid development of China’s railway transportation industry has made it increasingly prominent in the national economy and is closely linked to other industrial sectors.Research on the correlation and economic effects of the railway transportation industry,and clarifying the degree of connection between the railway transportation industry and other industries,can provide theoretical guidance for the stable operation of the national economy and the common progress of the railway transportation industry and other industries.The main research contents are as follows:This study sorts out China’s input-output table,integrates all national economic and industrial sectors into 20 industrial sectors including railway transportation,establishes corresponding industry-related indicators,and constructs input-output models.The final analysis uses the structural coefficient,intermediate input rate,intermediate demand rate,direct consumption coefficient,complete consumption coefficient,direct allocation coefficient,complete allocation coefficient,influence coefficient,and sensitivity coefficient,followed by Leontief in the input-output table The inverse matrix performs structural decomposition,decomposing the economic effects of the railway transportation industry into multiplier effects,spillover effects,and feedback effects.The input-output model was used to calculate the 2017 China input-output table,and quantitative analysis of each indicator revealed the internal relationship between the railway transportation industry and various industrial sectors of the national economy.The results show that the salary of the railway transportation industry workers accounted for the largest proportion in the initial input structure.It belongs to the labor-intensive industry sector,and the final use is mainly for final consumption expenditure.The direct consumption coefficient of the industrial sector to the financial industry is the largest,indicating that the financial industry contributes the most to the railway transportation industry.Its complete consumption,direct distribution,and complete distribution coefficient for the manufacturing industry are the largest among the industrial sectors of the national economy.Not only does it have a strong full pulling effect on the manufacturing industry,it also has a strong direct and complete supply promotion effect.It has a lower influence and a sensitivity coefficient,but the influence coefficient is close to twice the sensitivity coefficient.This shows that the railway transportation industry is mainly driven by demand,with the largest spillover effect and the smallest feedback effect,indicating that its impact on the national economy is dominated by the spillover effect.The comparative analysis of relevant indicators of the railway transportation industry in 2002,2007,2012 and 2017 reveals the degree of change in the correlation between the railway transportation industry and various industrial sectors of the national economy.The results show that the industrial structure of the railway transportation industry has not changed substantially.It has always been a labor-intensive industry sector.The final use is mainly used for final consumption expenditure.The intermediate demand rate remains high.The intermediate input rate was between 2007 and 2012.The qualitative leap has been completed,making the railway transportation industry realize the leap from the intermediate product-based industry to the intermediate product-based industry.Its direct consumption,complete consumption,direct distribution,and complete distribution coefficient of the manufacturing industry are relatively large.It shows that it has a strong dependence on the manufacturing industry,and its influence coefficient and sensitivity coefficient are lower than the social average,but the influence coefficient is much higher than the sensitivity coefficient,indicating that the radiation capacity of the railway transportation industry is relatively strong The spillover effect is always the largest and the feedback effect is always the smallest,indicating that its impact on the national economy has always been dominated by the spillover effect.
