摘要
本文从进口企业处于买方地位进而面临信息不对称和信息搜寻成本视角,厘清互联网影响企业进口行为的理论机制,并基于中国工业企业和海关数据库,使用匹配倍差法进行实证研究,有如下发现:第一,互联网存在质量搜寻效应,采用互联网技术可显著提升企业进口质量,进一步从产品层面来看,互联网的使用并未促使企业进口集合中的在位产品质量提高,而是通过进口更高质量的新产品,实现加总进口质量升级;第二,作为质量搜寻效应的间接结果,互联网还存在进口集合内部的结构再配置效应,进口种类并未扩张,但进口核心度明显提升,进口集合得以优化。本文还发现线下信息网络对互联网具有一定替代作用,当企业处于线下信息网络相对稀缺的城市或行业时,率先采用互联网技术对企业进口质量升级和进口集合优化的正面促进作用力度更大。
This paper clarifies the theoretical mechanism of the Internet’s influence on the import behavior of enterprises from the perspective of importer’s buyer position facing information asymmetry and information search costs.Based on the matching database of Chinese industrial enterprises and customs,the matching difference method is used for empirical testing,and the main results are as followed:First,the Internet has a quality searching effect.The use of Internet technology can significantly improve the importer’s quality.From the perspective of product dynamics,the use of the Internet has not promoted the quality of incumbent products in the imported products mix,but has improved the quality of products by importing high-quality new products which led to an upgrade of aggregate import quality.Second,as a result of the quality searching effect,the Internet still has a structural reconfiguration effect within the imported products mix.The varieties of import products have not expanded,but the core degree of imports has increased significantly which can optimize the imported products mix.This paper also finds that offline information networks have a certain substitution effect on the Internet.When companies are in cities or industries where offline information networks are relatively scarce,the first to adopt Internet technology will have a greater positive effect on the upgrading of import quality and the optimization of imported products mix.
