A Statistical Study On The Realationship Between R&d Capitalization And Economic Growth

The process of economic globalization is accelerating,knowledge is rapidly updated,and scientific and technological innovation plays an increasingly prominent role in economic development.In particular,R&D activities have become the number one motivation for economic development.SNA 2008 redefined the definition of R&D capital and will be able to give the R&D expenditures that owners bring economic benefits are included in the fixed assets project.Many countries have adjusted their national accounts accounting system and set up their own satellite accounts.The integration of R&D into capital has more objective measures of technological progress and economic growth.It enables us to understand the relationship between technological progress and economic growth more accurately and comprehensively,and is more conducive to maintaining the consistency and completeness of scientific and technological statistics.According to SNA2008 definition of R&D,R&D will be treated as capital no longer treated as intermediate consumption into the gross national product accounting,the total cost method for national and sub-provincial R&D output calculation,and the use of supply and demand balance through R&D output and import and export Calculate R&D fixed capital formation.From the perspectives of production method,income method and expenditure method,this paper summarizes the changes of the main variables caused by GDP accounting,and uses the expenditure method to account for the formation of R&D capital of industrial enterprises into GDP.Inventory method to calculate R&D capital stock,and finally establish a spatial model to study the relationship between R&D capital and economic growth.According to R&D capitalization calculation and national economic accounting theory,since the R&D has been capitalized,the economic structure has changed,causing a decrease in consumption,increasing investment,a decrease in consumption rate,an increase in capital formation rate,and a contribution of consumption and investment to economic growth.Variety.Based on the R&D data of various regions from 2001 to 2015,it was concluded that the R&D capitalization caused the real GDP growth rate to increase by 2.18 percentage points.From 2001 to 2015,the average constant-price GDP growth rate was 1.98 percentage,and the per-In 2015,the provincial R&D capital stock,of which the R&D capital stock in 2015 was the highest in Guangdong Province at 3162.98 billion yuan,followed by Jiangsu Province at 310.539 billion yuan,and analyzed the relationship between R&D capital and economic growth.Based on the data of R&D capital and economic growth in 30 provinces and the Moran index,LM,Robust LM and Wald tests,the spatial Dobbin model was established and the relationship between R&D and economic growth was studied.It was concluded that not only the R&D capital in the region but also the economic growth in the region Have an impact,spillover of R&D in adjacent areas also promote economic growth in the region.According to the research results,the following suggestions are put forward:(l)R&D capitalization research in response to national policies(2)Establishment of own R&D satellite account(3)Two-pronged promotion of R&D investment level in China(4)Further promotion of R&D capital to economic growth utility.
