区域服务贸易协定及其承诺深度对离岸服务外包增加值的影响

The Impact of Regional Service Trade Agreements and Commitments Depth on the Value Added of Service Offshoring

基于区域贸易协定的迅猛发展且越来越重视对服务问题的谈判,本文从理论和实证两个方面探讨了区域服务贸易协定及其承诺深度对离岸服务外包增加值的影响。本研究认为,区域服务贸易协定及其承诺深度主要通过削减服务外包交付成本、改善契约制度环境以及提高服务外包生产率等途径提升离岸服务外包增加值。实证结果表明:(1)区域服务贸易协定将促使离岸服务外包增加值平均提升27.00%,而每增加1个部门的开放,将会使得增加值平均提高11.91%;(2)从多期动态效应上看,区域服务贸易协定对服务外包增加值的影响持久深远。即使在区域服务贸易协定实施后的15年左右,仍具有显著的促进效应;(3)从承诺异质性效应上看,区域服务贸易协定“GATS+”特征和“完全承诺”深度有利于促进离岸服务外包增加值。本研究为中国通过积极参与区域经济一体化建设来推动服务外包产品、技术、品牌和标准等“走出去”提供了经验分析和政策参考。

Based on the rapid development of Regional Trade Agreements and the increasing emphasis on negotiations on service issues,the paper discuss the impact of Regional Service Trade Agreements and commitments depth on the value added of service offshoring from both theoretical and empirical perspectives.This study shows that Regional Service Trade Agreements and commitments depth can promote the value added of service offshoring by reducing service trade costs,improving the contractual environment,and increasing service productivity.The findings are as follows:first,Regional Service Trade Agreements will promote an average increase of 27.00%on the value added of service offshoring.Besides,increasing one more openness of service sector,there will be an average increase of 11.91%on the value added of service offshoring;Second,from the perspective of multiple dynamic effects,the impact of Regional Service Trade Agreements on the value added of service offshoring is long-lasting and far-reaching.Even within about 15 years after the implementation of Regional Service Trade Agreements,there is still a positive promoting effect;Third,considering the heterogeneity of commitments,the"GATS+"characteristic and the depth of"full commitments"in Regional Service Trade Agreements are conducive to promoting the value added of service offshoring.This study provides empirical analysis and policy reference for China to promote the"Going Abroad"of service business,technologies,brands,and standards by actively participating in Regional Economic Integration.
