互联网、产品差异化与企业出口定价

Internet,Product Differentiation and Enterprise Export Pricing

本文将互联网引入垄断竞争模型,纳入产品质量和生产率双重异质性,从微观角度研究了互联网对企业出口定价的影响。总体上,互联网对企业出口定价具有正向影响。区分产品差异化程度后,发现当产品具有同质性时,互联网与出口价格负相关;当产品具有异质性时,互联网与出口价格正相关。机制检验发现,互联网对企业出口定价的“成本节约效应”显著,而对“质量升级效应”的发挥存在门槛值;对低质量样本,互联网的质量升级效应表现显著,这可能与互联网指标的选取有关。异质性分析表明,互联网对企业出口定价的积极影响具有普遍性,尤其是对国有企业、西部地区企业、高技术行业企业、高行业集中度和高产品集中度企业。本文指出,应进一步推进中国制造业企业的信息化建设和应用,提升企业互联网应用水平,以实现我国制造业升级和对外贸易高质量发展。

This paper discusses a monopoly competition model with the use of the internet and incorporates heterogeneity in product quality and productivity from a micro-perspective view to study the effects of the internet on enterprises’export pricing.According to the findings,the internet positively impacts enterprises’export pricing.After distinguishing the degree of differences in the products,the internet produces a negative correlation with export pricing when the products are homogeneous,but produces a positive correlation when the products are heterogeneous.The mechanism test reveals that the“cost-saving effect”of the internet on enterprises’export pricing is significant,whereas the“quality-upgrading effect”holds a threshold value.As far as the low-quality samples are concerned,the significance of the internet’s“quality-upgrading effect”may be due to the selection of internet indicators.The analysis of heterogeneity indicates that the positive impact of the internet on enterprises’export pricing exists extensively,especially for state-owned enterprises,as well as enterprises in the western regions,high-tech industry enterprises and those with high industry concentration and product concentration.This paper reveals that Chinese manufacturing enterprises should further promote the construction and application of informatization,and enhance their internet application level to realize the upgrading of Chinese manufacturing industry and high-quality development of foreign trade.
