This paper analyzes the effect of the development of the Internet on the share of small and medium-sized enterprises (SMEs) in total exports. We extend the Helpman, Melitz and Yeaple (2004) model to include the opportunity for firms to pay lower fixed export costs by exporting indirectly via well-established e-commerce platforms. SMEs self-select into the indirect exporting mode. In response to the development of the Internet, fixed costs of indirect exporting fall at a higher rate than fixed costs of direct exporting. Consequently, SMEs tend to account for a larger share in total exports as the Internet develops. Using two samples from the Exporter Dynamics Database, we find supporting evidence that the development of the Internet in the exporting country has a significant and negative effect on the share of exports by the top 5% or 25% of exporters, implying a larger share of SMEs. Moreover, we find that improved submarine cable infrastructure in the exporting country also leads to a lower share of exports by large exporters. These are in contrast to the estimated positive effect of telephone development in the exporting country, which may not disproportionately benefit indirect exporting via e-commerce platforms over direct exporting. Finally, we find an imperfect substitution relationship between e-commerce platforms and traditional intermediaries.

互联网与中小企业参与出口

本文分析了互联网的发展对中小企业在出口总额中所占份额的影响。我们扩展了 Helpman、Melitz 和 Yeaple(2004 年)模型,将公司通过完善的电子商务平台间接出口来支付较低固定出口成本的机会包括在内。中小企业自主选择进入间接出口模式。因应互联网的发展,间接出口的固定成本下降速度高于直接出口的固定成本。因此,随着互联网的发展,中小企业在总出口中的份额往往更大。使用来自出口商动态数据库的两个样本,我们发现支持证据表明,出口国互联网的发展对前 5% 或 25% 的出口商的出口份额有显着的负面影响,这意味着中小企业的份额更大。此外,我们发现出口国海底电缆基础设施的改善也导致大型出口商的出口份额下降。这些与出口国电话发展的估计积极影响形成对比,这可能不会对通过电子商务平台的间接出口比直接出口带来更大的好处。最后,我们发现电子商务平台与传统中介之间存在不完善的替代关系。我们发现,出口国海底电缆基础设施的改善也导致大型出口商的出口份额下降。这些与出口国电话发展的估计积极影响形成对比,这可能不会对通过电子商务平台的间接出口比直接出口带来更大的好处。最后,我们发现电子商务平台与传统中介之间存在不完善的替代关系。我们发现,出口国海底电缆基础设施的改善也导致大型出口商的出口份额下降。这些与出口国电话发展的估计积极影响形成对比,这可能不会对通过电子商务平台的间接出口比直接出口带来更大的好处。最后,我们发现电子商务平台与传统中介之间存在不完善的替代关系。
