Probing into the cause and efficiency of regional scientific and technical output via grey relational analysis
The analysis object of this paper is the six provinces and one municipality in East China, and the research method which is adopted is grey relational analysis. The research result shows that for the influence of scientific and technical output indexes, the greatest is both "expenditures for scientific and technological activities" and "R&D expenditures". The next is "scientists and engineers," and the lowest is "persons engaged in scientific and technological activities." The two indexes of less influence belong to the input of financial resources, and the two indexes of more affection are part of the input of manpower. Through the grey appraisement of sixteen and four indexes, we can find out the same conclusion: the regional scientific and technical productive efficiency of Shanghai is the highest; Jiangsu is the second; Fujian is the third; Zhejiang is the 4th; Anhui is the 5th; Shandong is the 6th; and the final one is Jiangxi. Further research suggests that when carrying on the analysis of scientific and technical efficiency, compared with sixteen indexes, the selected four indexes may be enough.
