| 摘要: |
| 将区域创新过程划分为科技研发阶段和成果转化阶段，采用基于DEA的Malmquist生产率指数测算我国两阶段区域创新绩效，结果表明：区域创新绩效存在明显的空间关联关系，呈以多个增长极为中心的组团分布，东部地区的创新优势区域相对密集，而中西部地区的创新增长极相对分散，各省份两阶段创新绩效的变化存在不同程度的差异。进一步构建科技研发绩效和成果转化绩效的动态空间面板模型，分析表明：两阶段区域创新绩效显著空间正相关，基本形成互动关联的协同创新链式结构，其中“学研”对“产”的知识溢出效应明显，而成果转化对科技研发的反馈影响较弱；分地区看，东部地区基本形成了强强联合的创新优势区域带，而中西部省份的链式创新结构尚不完整。应充分利用区域创新绩效的过程溢出和空间关联效应，强化成果转化对科技研发的反馈作用，破除区域创新壁垒，加强区域创新协作，进而提高区域创新能力和绩效。 |

| Abstract: |
| he regional innovation process can be decomposed into interrelated two stages, namely research process and commercial process. By constructing the Malmquist productivity index of DEA, this paper evaluates regional two-stage innovation productivities in China and finds obviously spatial correlation between them which are distributed in multi-growth-pole as the center of the group. In the east, innovative advantage regions are relatively concentrated, but in the Midwest, the innovative growth poles are relatively dispersed, and there is difference on different extents in the two-stage innovation performance change between different provinces. On this basis, the paper further incorporates the effects of value chain outflow and spatial correlation into two dynamic spatial panel models to separately estimate these effects on both regional research and commercial productivities changes. The analysis shows that there is significantly positive correlation between the two-stage innovation performances, that the coordinated innovation chain structure with interactive correlation is basically formed, among which the knowledge spillover effect of “learning and research” on “production” is significant, however, the feedback impact of research result commercialization on research and development is weak. In different regions, the east regions basically form the innovation advantage zones with the coordination of the strong with the strong, but the chain innovation structure in the Midwest is not perfect. China should sufficiently make use of the regional innovation spillover and spatial correlation effects to enhance the feedback effect of research results commercialization on research and development, break regional innovation barriers, strengthen regional innovation coordination, and further improve regional innovation ability and performance. |
