中国R&D投入与高技术产业研发产出的相关性分析
Study on the correlation between China’s R&D budget and hi-tech industry outputs
【摘要】 本文对中国R&D存量与中国高技术产业各个产出指标进行了相关检验及回归分析,研究发现,1995 -2005年中国R&D资本存量与该行业专利申请受理数量、销售收入、利润和新产品销售收入等指标都存在显著的正线性相关关系;高技术产业三资企业专利申请受理数量、销售收入、利润指标和新产品销售收入与中国R&D资本存量呈现强正线性相关关系;国有控股企业的利润指标与R&D资本存量的相关性没有通过显著性检验。通过spearman等级相关分析,高新技术产业国有企业专利申请受理数量、销售收入和新产品销售收入同R&D资本正相关,但相关系数远不如三资企业。
【Abstract】 This paper conducts correlation tests and regression analysis on China’ s R&D reserve and hi -teeh industry outputs.It is re- vealed that during 1995 and 2005,R&D reserve shows a positive linear correlation with the number of accepted patent application,sales income,profit and the sales volume of new products.Further studies disclose that the positive correlation is highly significant in the Sino -foreign joint ventures,cooperative businesses and exclusively foreign- owned enterprises.However,profit of the state- controlled en- terprises does not display a significant correlation with the R&D reserve.Besides,by means of Spearman Rank Correlation Analysis,we find that although numbers of accepted patent application,sales volume and sales volume of the new products are positively correlated with R&D reserve in all of the four types of enterprises mentioned above,the correlation coefficient in the SOEs is remarkably lower.
