互联网化与企业出口产品多元化:中国的经验证据

Internetization and Export Product Diversification of Firms:Evidence from China

互联网经济时代,市场信息愈发成为企业开发新产品的关键要素。文章基于多产品的异质性企业模型,引入互联网化和企业研发强度,从微观视角揭示企业互联网化对企业研发强度和出口产品多元化的影响。研究表明,互联网化显著提高了中国企业出口产品多元化水平,且企业研发强度是其中的重要渠道机制。进一步分析发现,互联网化对中国企业出口产品多元化的作用对于非国有企业、高技术行业的企业的影响比国有企业、低技术行业的企业更大;互联网化促进产品种类多元化的作用对于非出口企业和非出口产品同样成立。

In the era of Internet economy,market information has increasingly become the key factor for firms to develop new products.Based on the heterogeneous firms′model of multiple products,this paper introduces internetization and firms′R&D intensity,and reveals the impacts of firms′internetization on their R&D intensity and export product diversification from a micro perspective.The findings show that the internetization has significantly improved the diversification level of Chinese firms′export products,and firms′R&D intensity is an important channel mechanism.Further analyses show that the effect of internetization on the diversification of Chinese firms′export products is greater for non-state-owned enterprises and firms in high-tech industries than for stateowned enterprises and firms in low-tech industries.The role of the internetization in promoting diversification of product categories is also true for non-export firms and non-export products.
