Contribution Rate Of Technological Progress In Shaanxi Province's Transportation Industry And The Influencing Factors

The transportation industry is an important part of the national economy.As the carrier of the national economy,the transportation industry is connected with social production and consumption.It is the basic industry and service industry of the national economy.Previous scholars have done a lot of research on the transportation industry,but there are relatively few studies on the technological progress of the transportation industry.Research and can accurately measure the contribution rate of technological advancement in the transportation industry,help to grasp the technological development status and industry dynamics of the transportation industry,help the transportation industry formulate and implement effective policies,and realize the informatization,intelligence and technology of the transportation industry.It effectively promoted the high-quality development of Shaanxi's transportation industry and national economy.The paper firstly elaborated the background of the topic,the purpose and significance of the research and the research status at home and abroad,and studied and collated the relevant theoretical concepts and basic methods.Taking the technological progress of Shaanxi's transportation industry as the research object,the focus is on the accurate measurement of the contribution rate of technological progress,followed by the analysis of the factors influencing the contribution rate of technological progress.In constructing the calculation model,the potential growth coefficient is modified by introducing the potential effect coefficient to the equation of the dynamic growth rate of Solow,and the degree of resource input in the economic system and the degree of utilization of resource efficiency are considered to be equally important.The purpose is to accurately measure the technical progress of the transportation industry.Contribution rate.Finally,a linear regression model is used to make a least-squares estimate of the factors affecting the contribution rate of technological progress and analyze the regression results.The research conclusions are as follows:(1)Measure the extent of each element's input resource efficiency,and calculate the efficiency of each factor input by calculating the potential effect coefficient of each factor input,and obtain the potential effect coefficient of the comprehensive resource efficiency.1.0184;(2)Constructing the Solow dynamic growth rate equation model with the introduction of the potential effect coefficient correction to calculate the annual average contribution rate of technical progress of the transportation industry to economic growth is 57.32%;(3)Using this model to measure and obtain the last phase of the transportation industry The annual average contribution rates of capital stock and capital investment to economic growth during this period are 16.59% and 14.90%,respectively;(4)Linear regression method is used to perform least squares estimation of the factors affecting technological progress,and the estimation results are obtained from regional economic development level.The index weight of the impact of fixed asset investment on the contribution of technological progress is 86.91%,which is much higher than the index weight of education level and fiscal expenditure.Finally,according to the conclusions of the thesis,the policy suggestions for improving the contribution rate of technological advancement in transportation are given.
