Impact of coupling coordinated development of triple value chains on green total factor productivity
The coordinated development of the value chains at provincial,national,and global levels proves to be pivotal in facilitating international and domestic circulations and ensuring the soft landing of China's economy,while green input-output efficiency,under the context of high-quality development,has been identified as a core factor in evaluating the potential of enterprises.In this view,this study attempted to calculate the coupling coordination degree of triple value chains by tapping into the global input-output table,Chi-na's multi-regional input-output table,and data from listed companies.The Slacks-based Measure(SBM)method was employed to mea-sure the green total factor productivity enveloping undesirable output.The balanced panel data consisting of 770 listed companies in China in 2012,2015,and 2017,assisted by a multidimensional fixed-effects model,was used to estimate the impact of coupling coordi-nation degree of triple value chains on the green total factor productivity of enterprises.The results revealed that:① There existed a vir-tuous cycle in which the coupling coordination degree of triple value chains rose,the GVC embeddedness was fortified,and green total factor productivity increased,but its effect was attenuated as factor density increased.② Further analysis indicated that the forward coupling coordination degree of triple value chains brought about an effective and long-acting improvement in the green total factor pro-ductivity of enterprises,while the backward one produced a short but significant rise for labor-intensive enterprises in particular.To conclude,this paper arrives at several policy suggestions about coordinating value chains and optimizing industrial layout.First,govern-ments need to be more actively involved in evaluating the advantages of local enterprises to ensure that policy formulation is specific to local micro agents.In this regard,labor-intensive provinces or industries should possibly promote coupling coordinated development of triple value chains to enforce the transformation and upgrading of local enterprises and to achieve harmonized industrial development.Second,regarding factor input,more attention should be placed on resource allocation for local high-tech enterprises.On the other end,cross-regional cooperation should be encouraged to achieve the integration of production and supply so as to enhance the promoting ef-fect of forward coupling coordination on the endogenous growth of enterprises.The implementation of green environmental protection standards in supply chain processes should also be considered.Third,the tuning of policies and the convenience of transactions among provinces need to be strengthened.Enterprises of different regions must pursue market specialization,rather than being embedded in GVC discretely,to implement agglomeration effects to realize full industrial upgrade and break the technological barriers in China's do-mestic market.
