基础设施互联互通对出口经济体参与全球价值链的影响

本文利用亚洲开发银行（ADB)提供的贸易增加值分解数据构建出口经济体的全球价值链参与程度模型，实证检验各经济体间基础设施互联互通水平对各经济体参与全球价值链的影响。实证结果发现：基础设施互联互通水平促进了出口经济体在全球价值链中的前向垂直专业化参与率以及垂直专业化深度。贸易双方之间的技术差距、制度质量差距等因素会影响物流质量、双边联通变量对全球价值链参与程度的边际影响。技术差距、制度质量差距的增加会降低物流质量对出口经济体在全球价值链中前向垂直专业化参与率的促进作用，但会提高双边联通对出口经济体在全球价值链中前向垂直专业化参与率的促进作用。而技术差距、制度质量差距的变化对物流质量、双边联通对出口经济体在全球价值链中垂直专业化深度的促进作用没有影响。

THE EFFECT OF THE CONNECTIVITY OF INFRASTRUCTURE ON THE PARTICIPATION OF AN EXPORT ECONOMY IN GLOBAL VALUE CHAINS

Using the data of trade value added decomposition provided by Asian Development Bank (ADB), this paper constructs the global value chains participation of export economy, and then empirically tests the effects of bilateral connectivity index and logistics quality level of infrastructure on an export economy's global value chains participation. The results suggest that the level of regional infrastructure connectivity promotes the forward vertical participation rate, as well as the depth of vertical specialization of an exporting economy in the global value chains. Factors such as technological gaps and institutional quality gaps between trade partners would affect the marginal effects of logistics quality and connectivity of infrastructure on an export economy's global value chains participation. The increase in technology gap and institutional quality gap would reduce the promotion effect of logistics quality on the forward vertical participation rate while they would enhance the promotion effect of connectivity of infrastructure on the forward vertical participation rate, and they have no impact on the effects of logistics quality and connectivity of infrastructure on the depth of vertical specialization of an export economy in the global value chains.
