我国R&D投入对GDP三大产业的影响分析
Analysis of the Impact of R&D Investment on the Three Major Industries of GDP in China

为进一步提升中国科技创新竞争力，提高我国R&D投入水平，提升R&D投入使用效率，本文采用相关性检验、逐步回归模型等研究方法分别对物质资本存量、R&D经费内部支出、年末就业人数、R&D人员全时当量和R&D活动组成中的基础研究、应用研究、试验发展与GDP经济指标进行关联度及相互影响分析。每个自变量与GDP、R&D活动中的每个组成部分均与三大产业具有较强关联性，通过测算得出，与基础研究和应用研究相比，试验发展对于三大产业的影响力最为显著。中国高度重视R&D试验发展投入，本论文研究的R&D活动与三大产业关系之间的影响关系结论，能够为R&D投入促进经济社会发展提供有效的研究路径和方向，与此同时也能为政府决策咨询提供建议。
In order to further enhance China’s competitiveness in scientific and technological innovation, improve the level of R&D investment in China, and enhance the efficiency of R&D investment utilization, this paper uses research methods such as correlation testing and stepwise regression models to analyze the correlation and mutual influence among basic research, applied research, experimental development, and GDP economic indicators in material capital stock, internal expenditure of R&D funds, year-end employment, full-time equivalent of R&D personnel, and R&D activity composition. Each independent variable has a strong correlation with GDP and each component of R&D activities with the three major industries. Through calculation, it is found that compared with basic research and applied research, experimental development has the most significant impact on the three major industries. China attaches great importance to R&D experimental development investment. The conclusion of the impact relationship between R&D activities and the three major industries studied in this paper can provide an effective research path and direction for R&D investment to promote economic and social development, and also provide suggestions for government decision-making consultation.
