The Evaluation Of Economic Performance Of National Innovation And Its Influencing Factors

With the deepening process of internationalization and globalization,nations are paying more attention to enhancing national competitiveness through enhancing innovation capacity.Innovation can bring about the absorption and diffusion of knowledge and technology,thereby improving domestic R&D capacity and the level of scientific and technological development.With each country continuously investing in R&D capital,the performance of innovation process,the capacity of S&T transformation and factors affecting national innovation ability have attracted much attention.Firstly,this paper combs the literature of core journals at home and abroad about economic performance of national innovation and its factors affecting,and summarizes the current research results and main problems,then defines the concepts and summarizes the basic theories involved in this paper,and finally carries out empirical analysis.In the empirical analysis part,from the perspective of economic performance of production economics,the economic aggregate and economic efficiency of national innovation are analyzed respectively.Indicators of ultimate market value of innovation and summaried economic appregate of national innovation are analyzed respectively in the economic aggregate part.In the economic efficiency part,this paper chooses nations whose innovation scores rank the top 50 simulaneous in ?Global innovation Index?published in 2014,2015 and 2016,and introduces a non-chain two-stage DEA model to explore economic efficiency and the optimal allocation of intermediate output of nations.Furthermore,the economic performance of national innovation is estimated by setting weights to economic aggregate and economic efficiency.Finally the Bayesian model averaging method is used to explore the impact of input variables,environment variables and main body variables on economic performance of national innovation.We find: The economic aggregate indicators are affected by different nations' scale and degree of development,and summaried economic appregate is mainly affected by nations' scale.The overall innovation efficiencies of most nations in 2013~2015 are low,and there are significant differences among different nations' economic efficiency,but the differences are narrowed year by year.With the increase of GDP per capita,economic efficiency shows a "U" trend.The "U" bottom countries tend to diverge to the "U" side and converge year by year,and the "U" bottom is about $30,000 per capita GDP.The support of innovation intermediate output to economic development varies from country to country,but the overall support capacity is poor.Different intermediate output variables take different forms with the increase of per capita GDP: the problem of insufficient output of PCT patent applications in countries with lower per capita GDP is serious,but the number of scientific papers is close to the optimal allocation level;while countries with higher per capita GDP are easy to achieve the optimal allocation of PCT patent applications,but the problem of insufficient output of scientific papers is serious.By calculating the economic performance of national innovation based on the economic aggregate and economic efficiency,we can see that there is a big gap in the comprehensive score of economic performance among different nations in the sample period.Different countries should adjust their economic performance level accordingly.The economic performance of national innovation mainly depends on the economic scale of a country.Capital factors,innovation environment factors and subject factors affect the economic performance of national innovation from different perspectives.Different types of countries should formulate corresponding improvement strategies according to their own level of economic performance of national innovation,the support of innovation intermediate output to economy and the factors affecting the economic performance of innovation.
