The Research On The Impact Of The Development Of High-tech Industry On Economic Growth In Northeast China

The development of high-tech industry plays an important role in promoting economic growth.High technology industry has the characteristics of high investment,rapid development,high scientific research personnel and strong penetration to other industries,the development of high technology industry is the only way for a country to change from labor intensive to capital intensive.The rapid economic development of developed countries such as Europe and the United States depends on high technology industries for the huge profits gained from foreign trade.After the 2008 financial crisis,China’s economic growth continued to be weak.It has proved that it is far from enough to rely solely on the development of traditional industries to promote economic recovery.It is imperative for China to develop high-tech industries and enhance the international competitiveness of products.In recent years,the high technology industry has made rapid development in our country,especially in the eastern region,the high technology industry has developed rapidly,which greatly promoted the development of regional economy.As the old industrial base in our country,the northeast region has a good industrial base and the development of high technology industry has good conditions.However,relative to the other regions of our country,the development of high technology industry in the northeast is lagging behind,which is the main factor restricting the economic rejuvenation of the Northeast region.Based on the theory of industrial development,economic growth theory and regional economic development theory,the influence of the development of high-tech industries in Northeast China on economic growth was analyzed by using grey relational model,panel regression model,threshold regression model and spatial Durbin model.The main contents and conclusions of the study are as follows:Firstly,through a comparative analysis of the development of high-tech industries in China and the Northeast region,it can be seen that the development of high-tech industry in the northeast is relatively backward,both in the overall,or in the high-tech industry subdivision industry,and the eastern region,the central region and the western region there are some gaps,are lagging behind the national average.This is mainly because the high-tech industry in northeast China is small in scale,slow in growth,uneven in internal development,weak in technological innovation,imperfect in relevant policies and regulations,and insufficient support from the government for high-tech industries.However,the geographical advantages of northeast China are obvious,with abundant natural resources,good industrial development foundation,and great potential for the development of talents in high-tech industries,which lay the foundation for the rapid development of high-tech industries.Secondly,the impact mechanism of high-tech industry on economic growth is as follows: firstly,the absolute scale of high-tech industry is expanding,which will directly lead to the increase of total economic output;secondly,the relative scale of high-tech industry is rising,which can promote the optimization and upgrading of industrial structure and accelerate economic growth;thirdly,the investment in R&D of high-tech industry is sustained.Continuous growth,relying on its R&D advantages,constantly promote technology and product upgrading,guide the industry to high-end development,and then promote economic growth;Fourth,high-tech industry technology and product upgrade is fast,short cycle,industry scale continues to grow and grow,thereby promoting economic growth.Through empirical analysis,we can find that the development of high-tech industries in the northeastern provinces of China has a significant impact on economic growth.Thirdly,this paper divides the high-tech industry into five industries: pharmaceutical industry,aerospace industry,electronic and communication equipment industry,computer and office equipment industry,medical equipment and instrument manufacturing industry,and uses panel data model to empirically analyze the sub-industries of high-tech industry in Northeast China.The impact of economic growth is compared with that of the high-tech industry in the eastern region.From the calculation results,it can be found that the pharmaceutical manufacturing industry in the northeast region has the greatest pulling effect on the local economic growth,followed by the medical equipment and instrument manufacturing industry.The development of aerospace manufacturing industry has restrained the local economy.In addition to the negative effect of aerospace manufacturing industry on economic growth in eastern China,the pulling effect of other high-tech industry Subdivisions on economic growth is significantly higher than that in Northeast China,which also shows that the development of high-tech industry subdivisions in Northeast China is relatively lagging behind,and the pulling effect on economic growth is relatively small.There is a lot of room for development.Fourthly,taking the main business income,R&D expenditure and specialization agglomeration index of high-tech industry in Northeast China as threshold variables,this paper uses non-dynamic panel threshold model to study the threshold characteristics of the impact of high-tech industry and its sub-sectors on economic growth in Northeast China.Through the research,we find that the main business income of high-tech industries in Northeast China has a single threshold effect on economic growth,and the internal expenditure of R&D funds in high-tech industries has a double threshold effect on economic growth.When the development scale of high-tech industry in Northeast China expands to a certain level,the main business income of high-tech industry plays a marginal decreasing role in promoting economic growth.When high-tech industry innovation increases investment in the initial stage,the positive effect of R&D expenditure on economic growth is increasing marginally.When the logarithm of R&D expenditure in high-tech industry exceeds 13.1726,the marginal effect on economic growth will decrease with the increase of R&D expenditure.From the point of view of subdividing industries,the main business income and R&D expenditure of the pharmaceutical manufacturing industry,communication equipment manufacturing industry,computer and office equipment manufacturing industry and medical instrument manufacturing industry in Northeast China have a threshold effect on economic growth.The main business income of the aviation,spacecraft and equipment manufacturing industry has a threshold effect on economic growth.There is no threshold effect.Fifthly,by constructing the spatial Durbin model of the scale of high-tech industries and regional economic growth,we find that,firstly,from 1997 to 2015,the scale of high-tech industries in Northeast China has declined relatively,and the spatial agglomeration effect of the scale of high-tech industries in Northeast China is not significant;secondly,high-tech industries have obvious effects on economic growth.The author’s role in promoting the development of high-tech industries has a certain spillover effect on regional economic growth.At the same time,the existence of high-tech industry absorption effect makes the development of high-tech industry in some areas inhibit the economic growth of adjacent areas;thirdly,regional labor force and regional capital have significant positive effects on economic growth,and the pulling effect of labor force on regional economic growth is more prominent.The regression coefficients of labor force,capital and spatial weight matrix are significantly negative,which shows that the increase of local labor force and capital will have a certain negative impact on the economic growth of neighboring areas.Fourthly,the regression coefficients of effective invention patents of Industrial Enterprises above regional scale to measure technological progress are negative,indicating that invention patents are given to the market.The economic benefits brought by the field take a long time and lag behind.In summary,the development of high-tech industries in Northeast China is relatively backward,and the pulling effect on regional economic growth is not significant.Under the background of the national strategy of revitalizing Northeast China’s economy,Northeast China should seize the opportunity of policy,enhance economic openness,enhance the depth and breadth of regional financial market development,and deepen the market.Reform,release the vitality of high-tech enterprises,form an effective talent training and incentive mechanism,strengthen the guiding mechanism of technological innovation market in Northeast China,and provide preferential support policies.Only in this way can the high-tech industry in Northeast China develop rapidly,can it really promote the rapid growth of regional economy,and can it become a new driving force for the economic revitalization of the old industrial base in Northeast China.
