【摘要】：信息网络是新的生产力代表,是区域实施创新驱动发展战略的先导力量。利用2003-2013年中国30个地区的面板数据,从基础设施、产业支撑和终端应用三个层面设计指标构建信息网络发展指数,并进行有效测度和考察。在此基础上,采用两步差分GMM法实证检验信息网络发展对区域创新的整体效应、结构效应以及条件约束。结果表明:信息网络发展指数存在空间分布不均衡现象,呈现出"东高西低"的阶梯状分布,且不同省市之间表现出较大的发展差距;信息网络发展对区域创新存在显著的正向整体效应;结构效应中,信息网络终端应用对区域创新的促进作用最为突出,而产业支撑尚未表现出显著的区域创新效应;信息网络发展对区域创新的影响还存在明显的条件约束,经济发展水平低下会弱化信息网络发展对区域创新的积极作用。因此,应迈开"互联网+"步伐,提升信息网络相关产业的整合能力和融合能力,并充分考虑地区差异,为中西部地区信息网络发展与区域创新提供坚实的经济基础和友好的政策环境,改善信息网络发展的空间分布不均状态,缩小区域间与区域内的发展差距。
[Abstract]:Information network is the representative of new productivity and the leading force of regional innovation-driven development strategy. Based on the panel data of 30 regions in China from 2003 to 2013, the index of information network development is constructed from three aspects of infrastructure, industry support and terminal application, and the effective measurement and investigation are carried out. On this basis, the two-step differential GMM method is used to empirically test the overall effect, structural effect and conditional constraints of information network development on regional innovation. The results show that the information network development index is unevenly distributed in space, showing a ladder distribution of "east high and west low", and there is a large development gap between different provinces and cities. The development of information network has a significant positive overall effect on regional innovation. Among the structural effects, the information network terminal application plays the most important role in promoting regional innovation, while the industrial support has not yet shown a significant regional innovation effect. The influence of the development of information network on regional innovation also has obvious constraints, and the low level of economic development will weaken the positive effect of the development of information network on regional innovation. Therefore, we should take the "Internet" step forward, enhance the integration and integration ability of information network-related industries, and take full account of regional differences, It provides a solid economic base and friendly policy environment for the development of information network and regional innovation in the central and western regions, improves the uneven spatial distribution of the development of information networks, and reduces the development gap between regions and regions.
