非研发创新支出对高技术产业创新绩效的影响研究

Influence of non-R&D innovation expenditure on innovation performance of high technology industries

外部技术获取、技术改造等非R&D创新经费支出对高技术产业创新绩效既可能产生"促进效应",也可能产生"替代效应"。运用17个高技术产业1995-2012年的面板数据进行实证研究,发现非R&D创新经费支出对高技术产业的专利产出和新产品销售收入整体上均产生了显著的正向影响,其中技术改造经费支出对专利产出主要体现为替代效应,但对新产品销售收入具有积极影响。外部技术获取整体上提升了高技术产业的专利产出水平,其中技术引进对专利产出产生了显著负面影响,但当与消化吸收费用支出产生协同效应时,其对专利产出的促进效应就会显现出来;消化吸收费用支出对新产品销售收入产生了显著的促进作用,而购买国内技术则有利于提升专利产出水平。

Non- RD expenditure may have both promotion effect and substitution effect on the innovation performance of high technology industries. The influence of distribution of non- RD expenditure on innovation performance of high technology industries is empirically studied with the panel data of industries from 1995 to 2012. It is found that non- RD expenditure on the whole has positive effect on both patent production and sales revenue of new products of high technology industries,among which expenditure for technical renovation mainly has substitution effect on patent production whereas positive effect on new product sales revenue. Outside technology access as a whole has positive effect on patent production,among which expenditure for acquisition of foreign technology has significantly negative effect on patent production,but when considering its synergistic effect with expenditure for assimilation of technology,its promotion effect on patent production appears. Expenditure for assimilation of technology has significantly promotion effect on sales revenue of new products,while expenditure for purchase of domestic technology has significantly positive correlation with patent production.
