The Influence of Import Complexity on Domestic Value-Added Ratio of Export of Guangzhou Enterprises
Based on the data of China Industry Business Performance,China Customs Trade and CEPII-BACI from 2000 to 2013,this paper systematically examines the relationship between import sophistication and the domestic value-added ratio(DVAR)of export for enterprises of Guangzhou.The results show that the import sophistication significantly improves the domestic value-added ratio of export of Guangzhou enterprises.R&D innovation behavior has a significant moderating effect on the import sophistication of Guangzhou enterprises,that is,enterprises with a higher degree of R&D innovation promote the improvement of export DVAR of Guangzhou enterprises through the import sophistication;Mechanism test shows that the significant mediating variables of the effect of R&D innovation on export DVAR of Guangzhou enterprises are the cost mark-up rate and the relative price of imported intermediates and domestic intermediates.In order to promote the increase of domestic value-added ratio and competitiveness of Guangzhou enterprises,it is necessary to accelerate the upgrading of import policy from export-oriented to innovation-oriented.
