政府在R&D链条各阶段的资金投入分配比例, 应立足于政府资金在各阶段的投入产出效率以及与企业资金的效率比较。本文基于2009-2013年省级面板数据的计量分析结果表明:政府资金的投入产出效率从高到低依次为基础研究、应用研究、试验发展, 企业资金的投入产出效率与政府完全相反;在基础研究和应用研究阶段, 政府资金的投入产出效率显著高于企业资金, 而在试验发展阶段, 政府资金的投入产出效率显著低于企业资金。因此, 按照效率优先原则, 我国政府应大幅增加对基础研究和应用研究的资金投入, 降低对试验发展的资金投入比例, 并选择能够产生对企业资金投入产生刺激效应的试验发展领域进行集中式投入。
Abstract
When government funds are invested at different stages of R&D, two factors should be considered: the efficiency of government funds at different stages of R&D, and the efficiency differences between government funds and enterprise self-raised funds. Compared with other countries, the ratios of government funds invested at the basic research stage and the applied research stage are smaller in China, while the ratio of investment at experimental development stage is bigger. The result based on the Provincial-level panel data analysis in 2009-2013 shows that: at the basic research and the applied research stages, the government funds have more positive innovation effects than enterprise self-raised funds; at the experimental development stage, the government funds invested have no significant effects; the government funds have a more positive effect at the basic research stage than atthe applied research stage. We suggest that government should increase the percentages of investment at the basic research and the applied research stage, and reduce the percentages of investment at the experimental development stage.
