摘要
本文探讨了数字产品进口对企业出口技术复杂度的作用机制,并在全面识别数字产品的基础上,考虑“进口来源国数字经济”综合构造数字产品进口指标,继而匹配2000—2013年中国工业企业和海关贸易数据对相关命题进行实证检验。研究发现:(1)数字产品进口显著促进了企业出口技术复杂度的提升;(2)进一步地,数字产品进口主要通过“提升企业生产率”和“促进出口产品多样化”两种渠道提升了企业出口技术复杂度;(3)区分地区、行业、企业和产品异质性后发现,该作用效果在数字经济发展水平较高地区、劳动密集型和竞争程度低的行业、本土企业和创新水平高的企业,数字资本品的进口中更为显著。本文从经验上证明了“以进口强出口”的发展模式仍然合理,对新时期评估中国“数字贸易”政策的经济效益有着重要意义。
This paper discussed the impact mechanism of digital product import on the technical complexity of enterprise export, considered the “digital economy of import source country” to comprehensively construct the import index of digital products on the basis of comprehensive identification of digital products, and then empirically tested the relevant propositions by matching data between Chinese industrial enterprise database and customs trade database from 2000 to 2013.The study finds that:(1) The export technology complexity of enterprises has been promoted by the digital product import;(2) Further, the import of digital products has increased the technological complexity of enterprises’ export mainly through two channels: improving enterprise productivity and promoting the diversification of export products;(3) By distinguishing the heterogeneity of regions, industries, enterprises and products, the effect is more significant in regions where there are higher development level of digital economy, in labor-intensive industries and lower competitive ones, in local enterprises or that witch higher innovation level, and in products which always come from the import of digital capital goods.The paper empirically demonstrates that the development model of “strengthening exports with imports” is still reasonable, which is of great importance to evaluate the economic benefits of China’s “digital trade” policy in the new era.
