城市轨道交通产业投资对当年投资乘数的影响研究——以湖南数据为例

不同的当年投资乘数对于经济增长的作用不同,因此,投资乘数的计算可以准确测量投资对经济增长的促进作用。通过计算湖南城市轨道交通产业投资对湖南当年投资乘数的影响,可以预测未来湖南的投资乘数及其经济增长。通过研究可以发现发展轨道交通产业不仅对湖南经济增长率有着现实贡献,而且能够通过投资乘数变化对总供给函数的影响,来延长发掘该产业对湖南经济增长潜在的未来的贡献。

The Study on the Influence of Hunan Urban Rail Industry Investment on Hunan Current Investment Multiplier in the Current Year, and the Prediction of the Multiplier

At present,Hunan urban rail industry is in the construction investment period,so it is bound to have all kinds of effects on the regional economic development.Those effects are realized mainly through the industry' linkage effect.From the microscopic perspective,the effects mainly reflect in the industry's influence on the upstream and downstream industry.From the macroscopic perspective,the effects primarily reflect in the influence on the operation of the economy.Therefore,this paper attempts to use the i...
