服务业、制造业中间品贸易自由化的协同效应——基于出口产品质量的视角

On the Synergistic Effect of Intermediate Trade Liberalization in Service Industry and Manufacturing Industry:From the Perspective of Export Product Quality

以出口产品质量为切入点,分别以进口关税降低和FD I管制放松表示制造业和服务业中间投入品开放,探讨制造业中间品和服务业中间品贸易自由化对企业出口产品质量提升的协同效应。通过构建包含制造业和服务业中间投入的出口产品质量内生选择模型阐述了协同效应的发生机制,在此基础上实证验证了协同效应的存在。异质性分析还表明:除交通运输业外,金融、电信和批发零售业均与制造业中间投入关税降低存在协同效应;股权限制、审查核准和其他限制的FDI中间投入管制放松与制造业中间投入关税降低存在协同效应,而关键人员限制放松的协同效应则不显著。此外,还发现这种协同效应在生产率较低的企业中更为显著,而在外资企业和加工贸易企业中表现较弱。

Taking the export product quality as the starting point,this paper uses the reduction of import tariff and the relaxation of FDI control to express the opening of intermediate input products in manufacturing and service industries,so as to discuss the synergistic effect of trade liberalization of intermediate goods in manufacturing and service industries on the improvement of export product quality.Firstly,it elaborates the occurrence mechanism of the synergistic effect by constructing an endogenous selection model of the quality of intermediate input export products,including the manufacturing industry and the service industry;on this basis it conducts an empirical test to verify the existence of the synergistic effect.The results of the heterogeneity analysis show that,except for the transportation industry,the finance,telecommunication,wholesale and retail industries all have synergistic effect with the reduction of intermediate input tariff in the manufacturing industry.There exists a synergistic effect between the deregulation of FDI intermediate input with equity restriction,examination and approval and other restrictions,while the synergistic effect of the relaxation of key personnel restriction is not significant.In addition,it is also found that the synergy effect is more significant in the enterprises with lower productivity,but in the foreign-funded enterprises and the processing trade enterprises,it is weaker.
