| Henan is located in central China and has convenient transportation.As a major agricultural province,it plays a decisive role in the country.With the implementation of the strategy of the rise of the Central Plains,Henan Province made significant achievements during the "Twelfth Five-Year Plan" period,with good economic development and substantial economic strength.With the improvement of people's living standards,Henan Province's economic development has ushered in many historical opportunities,but at the same time it faces many serious challenges such as environmental pollution and waste of resources.In the face of this series of problems,Henan Province proposes a change.Economic development methods,and scientific and technological advances have an important role in promoting the transformation of economic development methods.R&D activities are also the core of science and technology activities.Therefore,Henan Province's R&D investment can be used to improve the scientific and technological strength of Henan Province and transform the economic development of Henan Province.Ways and improve their competitiveness.After a systematic descriptive analysis of the current state of R&D investment in Henan Province,this paper empirically analyzed the relationship between R&D investment and economic growth in Henan Province using VAR model,impulse response,variance decomposition,and variable parameter state space model.(1)By establishing a VAR model,the elasticity of Henan Province's GDP in the previous year to the regional GDP of Henan Province was 0.4944,but the lag period was 2,and the elasticity coefficient became negative.-0.0722,the economic growth in Henan Province has a great inertia;the elastic coefficient of Henan Province's R&D investment in Henan Province's regional GDP was 0.0180 in the previous year.When the lag period is 2,the R&D investment in Henan Province is proportional to the regional GDP.The elasticity coefficient is still positive,at 0.0121,although the promotion of R&D investment in Henan Province has a long-lasting effect on economic growth;(2)It is concluded from the analysis of impulse response function and variance decomposition that R&D investment in Henan Province has positive effects on economic growth.To promote the role,and this promotion role has hysteresis,and over time,this positive promotion will become stronger and stronger;(3)A panel model was built using data on R&D input and economic growth of cities in the cities of Henan Province.It was concluded that R&D investment in different cities in cities in different cities in Henan Province promotes economic growth differently,and there are differences.(4)In order to study this difference Based on the intensity of R&D input,the R&D input of regional cities in Henan Province is divided into three categories:high,medium,and low.The panel models of the three are established and the economic growth is established respectively.The promotion is the largest,R&D moderate investment areas have the greatest role in promoting economic growth,R&D low investment areas have little impact on economic growth,so each region can not blindly increase R&D investment,but also consider the actual conditions of each prefecture-level city.(5)Based on the theory of the transmission mechanism of R&D investment influencing economic growth in Henan Province,an empirical study was conducted using the variable parameter state-space model for the transmission mechanism,and it was concluded that R&D investment in Henan Province promotes economic growth through total factor productivity,And is an effective transmission mechanism. |
