【摘要】：近年来电子商务成为网络信息化和国际市场化条件下进行资源配置的一个非常重要的途径,同时在对外贸易领域,贸易活动开始突破传统线下模式的束缚,传统企业趋于利用电子商务平台展开国际贸易,开拓国际市场。面对世界经济复苏缓慢,需求低迷的情况,研究电子商务的发展对出口会产生怎样的影响,其作用机制如何,是一个非常具有理论和现实意义的议题。本文在整理总结已有研究的基础上,梳理了前人关于电子商务的测度方法及其影响出口的研究方向和实证方法,结合中国电子商务和出口的现状,先从电子商务发展水平对出口的影响进行模型分析,在垄断竞争模型中引入代表电子商务发展水平的指标,通过电子商务对交易成本的降低来深入探讨电子商务水平的发展如何降低企业进入一国市场的固定成本,从而进一步扩大出口,提高出口总效益。然后文章选取2006-2013年中国31个省份的数据,构建了一套指标体系来测度中国电子商务发展水平,然后通过主成分分析法,结合融合降维的方法,综合因子载荷、特征值和指标贡献率计算每个指标的权重,并利用线性加权计算综合得分。在此基础上文章进一步就电子商务发展水平对出口影响的总效益及地区差异效应进行实证分析,文章得到结论:中国电子商务发展水平对出口存在正向推动效应,且这种作用存在地区差异,普遍来讲,中国电子商务发展水平高的地区对出口的影响更显著,但是,电子商务发展水平居中的广大中部地区和少数东、西部地区,由于其电子商务发展水平低于整体经济发展需求,对这些地区电子商务的投入带来的贡献率反而高于电子商务最发达地区。总体而言,本文通过理论与实证研究得到结论认为电子商务发展对中国出口贸易的总效益显著为正且地区差异效应明显,同时本文在分析形成这一现象的基础上就如何通过电子商务发展促进出口提出了相应的政策建议。
[Abstract]:In recent years, E-commerce has become a very important way to allocate resources under the condition of network informatization and international marketization. At the same time, in the field of foreign trade, trade activities have begun to break the shackles of traditional offline mode. Traditional enterprises tend to use e-commerce platform to open up international trade and open up international markets. In the face of the slow recovery of the world economy and the low demand, it is a very theoretical and practical topic to study how the development of electronic commerce will affect the export and the mechanism of its action. On the basis of summing up the existing research, this paper combs the former research direction and empirical method of e-commerce measurement and its influence on export, combined with the current situation of e-commerce and export in China. This paper first analyzes the influence of the level of e-commerce development on export, and introduces an indicator to represent the level of e-commerce development in the monopoly competition model. This paper discusses how the development of electronic commerce can reduce the fixed cost for enterprises to enter a country's market through the reduction of transaction cost by electronic commerce, so as to further expand export and improve the total export benefit. Then the paper selects the data of 31 provinces in China from 2006 to 2013, constructs a set of index system to measure the level of e-commerce development in China, then through principal component analysis, combined with the integration of dimension reduction method, comprehensive factor load, The weights of each index are calculated by the eigenvalue and the contribution rate of the index, and the comprehensive score is calculated by linear weighting. On the basis of this, the paper makes an empirical analysis on the total benefit and regional difference effect of the development level of electronic commerce on export, and draws the conclusion that the level of development of electronic commerce in China has a positive effect on export. And there are regional differences in this role. Generally speaking, areas with a high level of e-commerce development in China have a more significant impact on exports. However, the vast central region and a few eastern and western regions where the level of e-commerce development is in the middle, Since the level of e-commerce development is lower than the overall economic development demand, the contribution rate of e-commerce input to these areas is higher than that of the most developed areas. In general, this paper concludes that the total benefit of the development of electronic commerce to China's export trade is significantly positive and the effect of regional difference is obvious through theoretical and empirical research. At the same time, based on the analysis of the formation of this phenomenon, this paper puts forward some policy suggestions on how to promote export through the development of electronic commerce.
