摘　　要：基于产品价值链视角考察中国企业出口强度的信息化效应及其作用路径。在理论分析的基础上,采取世界银行提供的中国企业微观数据,运用iv-tobit模型和iv-oprobit模型基于总体及产品价值链维度进行实证验证。结果表明:企业出口强度对其总体及产品价值链各个环节的信息化水平都具有显著正向效应,且在产品价值链中下游环节的正向效应大于中上游环节;出口的学习效应和规模经济效应是总体及产品价值链各个环节的出口信息化效应显著存在的两个作用路径,但前者的中介作用大于后者。研究结论为企业在经济全球化背景下全方位推进产品价值链各个环节的信息化建设提供了全新思路和决策依据。The informatization effects of Chinese firms’ export intensity and their influence paths were analyzed from the perspective of product value chain in this paper. The internal mechanisms were analyzed theoretically,and then were tested empirically based on the dimensions of overall and product value chain through adopting the models of iv-tobit and iv-oprobit and the micro-data from the World Bank. The results show that: The export intensity has a significant positive effect on the informatization level in the overall and all aspects of product value chain,and the positive effects in the downstream of product value chain are greater than that in the upstream of product value chain;the learning effect and scale economy effect of export are two important paths for the export informatization effect,but the role of the former is greater than the latter in the overall and all aspects of product value chain. The above results could provide new ideas and decision-making basis for firm to promote the information construction of the entire product value chain in the context of economic globalization.
