采用中国省际2003～2008年内资高技术产业面板数据,实证检验技术转移、消化吸收对产品创新绩效的影响。从技术引进和国内技术购买两种不同的技术转移渠道考察,研究结果显示,技术引进一方面对中国内资高技术产业产品创新绩效具有显著的直接正面影响,另一方面作为调节变量显著提升了研发经费投入对产品创新绩效的边际贡献,国内技术购买对中国内资高技术产业产品创新绩效的影响不显著,消化吸收投入对中国内资高技术产业产品创新绩效贡献明显。进一步讨论,在技术引进过程中,中国内资高技术产业要注重消化吸收投入,提升技术吸收学习能力;要进一步繁荣国内技术交易市场,为中国内资高技术产业实施国内技术购买搭建平台。 相似文献

Innovation strategy and performance during economic transition: Evidences in Beijing, China 总被引：1，自引：0，他引：1
This paper evaluates the relevance of innovation strategy to various categories of Chinese firms and investigates its relationship with innovation performance during the economic transition of the 1990s. Data from 1244 Chinese firms in Beijing are used to ascertain the relative importance of different innovation objectives, along with the innovation strategies adopted by manufacturing firms. Results show that innovation activities were confined to the domestic sphere and mainly directed at quality improvement. Chinese manufacturing firms which obtained support from the government through the high-tech firm accreditation system generally perform better. They had already started moving away from a reliance on imported technology and equipment, and using indigenous R&D efforts to innovate for the coming market economy. 相似文献

文章利用1999-2014年中国27个省市自治区的高技术产业面板数据，借助空间杜宾模型（SDM），将自主创新、模仿创新和技术模仿等技术活动置于技术学习曲线理论框架下，实证考察了其对TFP的影响，辨明了中国高技术产业目前所处的发展阶段和技术活动的空间外溢效应。结果表明，现阶段高技术产业自主创新对TFP具有显著倒U型效应，模仿创新为显著U型效应，技术模仿效应不显著，即技术模仿对TFP提升的推动力减弱甚至基本消失，模仿创新的效应由不显著逐渐转为正向显著，自主创新的效应由正向显著逐渐转弱为不显著，且自主创新对TFP影响大于模仿创新，技术水平逐渐接近国际前沿。同时，技术活动具有明显的空间外溢效应，且外溢效应大于地区内部的直接效应。 相似文献

Knowledge spillovers through human mobility across national borders: Evidence from Zhongguancun Science Park in China 总被引：1，自引：0，他引：1
This paper investigates the impact of returnee entrepreneurs and their knowledge spillovers on innovation in high-tech firms in China. Using panel data for 1318 high-tech firms in Beijing Zhongguancun Science Park (ZSP) we find that returnee entrepreneurs create a significant spillover effect that promotes innovation in other local high-tech firms. The extent of this spillover effect is positively moderated by the non-returnee firm's absorptive capacity approximated by the skill level of employees. Multinational enterprises’ R&D activities positively affect the innovation intensity of non-returnee firms only when these local firms possess the sufficient level of absorptive capacity. Our findings have important implications for policy-makers and practitioners. 相似文献

本文运用随机前沿生产函数测算了中国高技术产业国有和非国有部门的自主创新效率变化和分解,并按所有制结构分组检验FDI质量特征的溢出效应。结果表明:(1)高技术产业非国有企业自主创新效率增速显著快于国有且增长源泉存在显著差异。非国有自主创新变化主要源于技术进步率和要素配置效率的快速增长,国有部门主要源于技术效率和规模效率的提升。(2)FDI质量特征和所有制结构会直接影响FDI对高技术产业技术溢出的程度甚至方向。外资技术含量、盈利能力有利于FDI对自主创新的正向溢出,平均规模不利于FDI对自主创新的溢出,但是这种影响仅仅表现为对国有企业的促进或限制,非国有企业并没有受到影响。FDI本地化程度是唯一对非国有企业产生显著正向溢出的外资质量特征。(3)外资数量与质量特征之间的交互作用在不同部门存在显著差异。 相似文献

Technology acquisition channels and industry performance: An industry-level analysis of Chinese large- and medium-size manufacturing enterprises 总被引：3，自引：0，他引：3
Guo Bin 《Research Policy》2008,37(2):194-209
Through an industry-level analysis of Chinese large- and medium-size manufacturing enterprises over the period of 1996-2001, this article investigates the direct and interactive contributions of four technology acquisition channels to industry performances in terms of innovation performance and productivity. These channels include in-house R&D, foreign technology transfer, domestic technology transfer, and inter-industry R&D spillover. We have found evidence of an important role of inter-industry R&D spillover in shaping and improving industry performance in China, which has been neglected by previous empirical studies concerned with Chinese industrial firms. The empirical results indicate that inter-industry R&D spillover and foreign technology transfer make significant contributions to both labour productivity and the level of total factor productivity in Chinese manufacturing industries. We have also found that in-house R&D and inter-industry R&D spillover share a complementary relationship in shaping innovation performance and total factor productivity in Chinese industry, and that in-house R&D relates to foreign technology transfer as a complement for labour productivity. Finally, on the mixed results among existing literature in the context of developing countries, this article argues that the commonly followed strategy in technology development, combined with government regulations, will play an essential role in determining the relationship between in-house R&D and foreign technology transfer. 相似文献

本文以2004-2012年30个省级行政区的相关数据为样本,借鉴技术溢出经典模型并考虑技术创新的时滞效应基础上,验证了高技术产业的技术创新活动对服务企业的影响。实证结果显示,高技术产业的专利存量对服务企业的溢出效应最为显著,且存在2年的时滞;高技术产业对服务业的研发经费间接投入也有显著的正向影响,时滞周期为3年;但高技术产业的新产品则对服务业发展的影响较弱或不显著。研究表明,高技术产业对服务业有着显著的技术溢出,能够通过有效改善高技术服务业的生产效率和技术水平,推动服务业实现创新驱动发展。 相似文献
