【摘要】：随着工业化和信息化的不断融合,互联网的快速普及与应用对实体经济的影响日益重要,已经成为促进中国经济新旧动能转换和产业结构调整升级的重要手段之一。与此同时,作为信息与知识密集型的高技术产业正在进入快速发展的"黄金时代",因此有必要研究互联网普及对高技术产业的影响,这对于更好地理解工业化和信息化融合具有重要的现实意义。但是要想准确分析互联网普及对高技术产业的影响,首先需要克服内生性问题,尤其是因果倒置问题。针对上述研究问题,在理论分析的基础上,本文利用互联网普及率这一指标代表互联网的普及与应用程度,将其引入到全要素生产率中,构建了以C-D函数为基础的互联网普及对高技术产业影响的计量模型,运用2003-2014年中国30个省、市、自治区的面板数据实证分析了互联网普及对中国高技术产业的影响,采用时间-地点双固定效应的最小二乘法进行回归,并通过滞后解释变量与工具变量法来解决内生性问题,保证结果的稳健性。研究结果表明:(1)互联网作为一种通用技术,同时也是重要的电信基础设施,互联网的普及不仅体现了互联网这种通用技术的扩散程度,还代表了互联网这种电信基础设施的应用水平,互联网普及可以通过促进技术创新、降低交易成本以及提升贸易开放度影响高技术产业的全要素生产率进而促进高技术产业发展;(2)基本实证结果表明互联网普及对高技术产业具有显著的正向影响,考虑内生性问题后的估计结果依然显著,互联网普及确实促进了高技术产业产出增长;(3)互联网普及对高技术产业的影响程度因时间和地区不同而有所差异,与中西部地区相比,互联网普及对东部地区的高技术产业的影响程度更高,2010年之后互联网普及对高技术产业的影响程度与之前年份相比显著提升;(4)政府支持对高技术产业产出的影响并未达到预期效果,金融发展水平和市场化水平有助于高技术产业发展。因此,加强互联网基础设施建设是加快中国工业化与信息化融合进程,促进中国高技术产业持续发展的关键所在。
[Abstract]:With the continuous integration of industrialization and information technology, the rapid popularization and application of the Internet has become increasingly important to the real economy, which has become one of the important means to promote the transformation of new and old kinetic energy of Chinese economy and the upgrading of industrial structure. At the same time, As the information and knowledge intensive high-tech industry is entering a "golden age" of rapid development, it is necessary to study the impact of Internet popularization on the high-tech industry. This is of great practical significance for a better understanding of industrialization and information integration. But in order to accurately analyze the impact of Internet popularization on high-tech industries, we must first overcome the problem of endogenicity. Especially the cause and effect inversion problem. Based on the theoretical analysis, this paper uses the Internet penetration rate to represent the popularity and application of the Internet, and introduces it into the total factor productivity. Based on C-D function, an econometric model of the impact of Internet popularization on high-tech industry is established, and panel data from 30 provinces, cities and autonomous regions in China from 2003 to 2014 are used to analyze the impact of Internet popularization on China's high-tech industry. The regression is carried out by using the least square method of time-place double fixed effect, and the endogenetic problem is solved by the method of delayed explanatory variable and tool variable. The research results show that the Internet is a universal technology. At the same time, it is also an important telecommunications infrastructure. The popularity of the Internet not only reflects the degree of diffusion of the Internet, which is a universal technology, but also represents the level of application of this telecommunications infrastructure of the Internet. The popularization of the Internet can promote technological innovation. The basic empirical results show that the popularization of the Internet has a significant positive impact on the high-tech industry, which is influenced by the total factor productivity of high-tech industries and thus promotes the development of high-tech industries by reducing transaction costs and increasing trade openness. After considering the endogenous problem, the estimated results are still significant. The popularity of the Internet does promote the output growth of high-tech industries. (3) the impact of Internet popularization on high-tech industries varies from time to time and from region to region, compared with the central and western regions. The impact of Internet popularization on the high-tech industry in the eastern region is even higher. After 2010, the impact of Internet popularization on the high-tech industry has increased significantly compared with the previous year. (4) the impact of government support on the output of high-tech industries. Did not achieve the desired results, The level of financial development and the level of marketization contribute to the development of high-tech industry. Therefore, strengthening the construction of Internet infrastructure is the key to accelerate the process of China's industrialization and information integration and promote the sustainable development of China's high-tech industry.
