The Research On The Regional Differences Of The Impact Of Information Technology Investment On Economic Growth In China

In the late 20 th century,the wave of information swept the world,how to seize the opportunity of information technology development,promote economic growth has become the focus of attention.In recent years,China's information industry is booming,the promotion and application of information technology has been strengthened,and the investment in information technology has increased rapidly.In 2014,China's largest electronic information industry completed the total sales revenue 14 trillion yuan,an increase of 13%.However,because of China's vast territory,the development of information industry in different regions has a big difference.2015,the top five provinces' main business income in scale electronic information manufacturing industry is about 340 times of the last five provinces'.The information technology investment as an important aspect of the development of information industry,has an important impact on the information industry,and economic growth.Therefore,the study that the regional differences on the impact of information technology investment on economic growth in China is important.The study of this issue will help us to understand the mechanism of information technology investment on economic growth more deeply.It also helps to make reasonable investment decision-making in information technology,which has important practical significance for economic growth in various regions.Based on the previous theories and related research,this paper defined the concept of information technology investment and economic growth,analyzed the mechanism of information technology investment on economic growth.In order to facilitate the analysis,provinces was divided into three categories by information technology investment,and analyzed the national and three regions' information technology investment and economic growth status.On this basis,built a panel model,made an empirical study on the impact of information technology investment on economic growth in various regions from 2002 to 2014,and explained the reasons for the differences.Finally,China should adhere to the development of information technology,enhance the scale of regional economy,according to the local conditions to invest in information technology,optimize the development environment,improve the relevant policies and regulations to promote regional economic growth.The main points of the paper are as follows: First,from the national point of view,information technology investment has a significant impact on economic growth because of the substitution effect,scale effect,agglomeration effect and spillover effect of information technology investment on economic growth;but because the impact of information technology personnel investment on economic growth is time lag,The impact of high input on economic growth is not significant.Therefore,we should insist on developing information technology and promote the increase of capital stock of information technology personnel.Second,from the investment area,the impact of information technology investment on economic growth in the low-input areas is the largest,high input area is lower,mainly due to high investment area is about to enter the information society development period of the primary stage,the impact of information technology investment on economic growth has weakened,medium investment areas and low investment areas in the preparatory stage of the transition period,information technology investment on the economic growth have a great impact,so the information technology capital investment should focus on medium and low input areas.Thirdly,as the information technology personnel investment in various regions,the impact of it on economic growth in the high investment area is relatively significant due to the large investment and high stock.The information technology of medium investment and low investment area have low stock of staffing,coupled with the lag of time,has led to the fact that the impact of information technology staff on economic growth is not significant in the region,so that all areas should increase staff input.The possible innovation of this paper are the research perspective and theoretical innovation.While paying attention to the influence of information technology investment on economic growth,we also pay attention to the differences among different regions.At the same time,on the basis of extending the extension of relevant theories,put forward the mechanism of information technology investment on the economic growth,forming the theoretical core.
