Study On The Efficiency Of Investment In Yangtze River Economic Belt

In recent years,the development of the regional economy has become more and more important to the economic development of the country.The Yangtze River Economic Belt is an important economic development area,and its development has an inevitable impact on China's economy.However,different valleys in the Yangtze River Economic Belt are affected by geography,history and other factors,there is a certain gap in economic development,economic development is unbalanced,resources are unreasonably allocated,and other problems are prominent.Therefore,it is necessary to evaluate the effectiveness of regional economic investment in the Yangtze River Economic Belt.In order to promote the coordinated development of the Yangtze River Economic Belt.The paper first introduced the economic development status and investment status of the Yangtze River Economic Belt,and then introduced the regional location of the upper,middle and lower reaches of the Yangtze River Economic Belt.Then,through data envelopment analysis,the effectiveness of the regional investment in the Yangtze River Economic Belt from 2011 to 2015 was illustrated from both vertical and horizontal angles.The input redundancy and output shortages were also analyzed and explained.Finally,they were adopted.The Tobit model was constructed to illustrate the factors affecting the investment effectiveness of the Yangtze River Economic Belt.The following conclusions were drawn: The DEA measurement results show that from the perspective of technical efficiency,the upstream and middle reaches of the Yangtze River Economic Belt are non-DEA effective and downstream areas from 2011 to 2015.The DEA is effective;from the perspective of pure technical efficiency,DEA is relatively effective in the downstream areas,and DEA is not effective in other regions.From 2011 to 2015,there was no phenomenon of redundant input and insufficient output in the upper reaches of the Yangtze River Economic Belt,and there were redundant input and insufficient output in the upstream and midstream regions.Tobit's estimation results show that the scale of investment is negatively correlated with investment effectiveness,and the level of economic development,urbanization rate,and self-sufficiency rate of finance are positively correlated with investment effectiveness.Finally,combined with the development of the Yangtze River Economic Belt,policies and recommendations havebeen put forward to increase investment efficiency,further narrow the regional economic development gap,and promote the coordinated development of the Yangtze River Economic Belt.
