基于投入产出法,对我国2005年、2007年和2012年制造业企业技术创新溢出与吸收能力进行了分析。结果表明,化学工业、通用专用设备制造业、仪器仪表及文化办公用机械制造业3个制造业部门作为高技术产业在整个技术创新系统中扮演技术创新扩散源泉的角色,制造业各部门间相对技术溢出能力总体呈下降趋势,化学工业、金属制品业、仪器仪表及文化办公用机械制造业3个制造业部门有较大的技术溢出,能够为制造业其他部门提供较多的技术创新量,有利于促进制造业结构变革。
Based on the input-output method, this paper analyzes the technological innovation spillovers and absorptive capacity of Chinese manufacturing enterprises in 2005, 2007 and 2012. The results show that the three manufacturing sectors in the chemical industry, general-purpose special equipment manufacturing industry, instrumentation and cultural office machinery manufacturing industry play the role of diffusion sources of technological innovation in the entire technological innovation system as high-tech industries, and all manufacturing sectors are relatively Technology spill-over capacity generally shows a downward trend. The three manufacturing sectors in the chemical industry, metal products industry, instrumentation and cultural office machinery industry have greater technological spillover and can provide more technological innovation to other sectors in the manufacturing industry, It is conducive to promoting the structural transformation of manufacturing industry.
