Value Chain Length,Structure Change of Export Enterprises and New Pattern of Development
As the international environment becomes increasingly complex and the advantages of the large-scale domes-tic market become more prominent,Chinese enterprises deeply integrated into the global value chain are entering a criti-cal juncture of coexisting risks and opportunities.In this context,guided by the new development pattern,how can we comprehensively delineate the characteristics of value chain length changes among different export enterprises and pro-mote the interaction between domestic and international circulation?This is both an important opportunity to form a pat-tern where domestic circulation promotes external circulation and a necessary path to expand high-standard opening up.To address this question,this paper leverages the dual advantages of macro value chain length and domestic value-added rate calculations at the micro enterprise level.We decompose the value chain length of export enterprises into three segments:domestic circulation,which focuses on the domestic market;interactive circulation,which connects domestic and international markets;and external circulation,which fully relies on external markets.Using data from the World Input-Output Database(WIOD)(2016),the China Industrial Enterprise Database,and China's customs import and export database,we systematically examine the structural changes in the value chains of Chinese enterprises and the current sta-tus of domestic and international circulation.The study reveals the following findings.First,the paper not only captures the individual differences among enter-prises but also uncovers new characteristics at the overall level,including the rapid increase in domestic circulation,a de-cline in interactive circulation,and the fastest decrease in external circulation behind the extension of export enterprises'value chains.These findings highlight the development dilemmas of China's manufacturing industry,including"domestic and international circulation separation"and"blocked technology spillovers".Second,unlike the multi-cycle coordinated improvement in general trade,non-general trade exhibits a significant separation of domestic and international circula-tion.This feature is more pronounced in domestic enterprises,low-technology sectors and central-western regions,which are characterized by weak import capacity,low division of labor coordination and insufficient industrial support.Third,al-though the results of the econometric model indicate that the substitution characteristic of domestic circulation for interac-tive circulation is robust,this paper finds that enhancing import capacity,digital intelligence levels,and industrial support can mitigate the substitution effect of domestic circulation on interactive circulation based on the sequential production characteristics of"import input decision→internal enterprise collaboration→domestic downstream support"in interactive circulation.Compared with existing literature,our work supplements and improves upon the following aspects.Firstly,by establishing a research paradigm capable of identifying the value chain length of different enterprises and connecting heterogeneous trade theories with value chain accounting,we detail the characteristics of value chain length changes among various types of entities.This approach effectively avoids the issues of macro studies failing to account for individual differences(trade types,ownership categories,and regional spaces)and micro studies transmitting macro calculation biases and high repetition ratios.Secondly,based on the division of labor characteristics coexisting in a complex international environment and a large domestic market,we systematically decompose the value chain length of enterprises into domestic circulation,inter-active circulation,and external circulation.This framework helps to understand the changes in value chain length from the perspective of dual circulation and addresses the lack of consideration for enterprise economic circulation,especially the interaction between domestic and international circulation,in related research.Thirdly,by comparing the circulation preferences and division of labor differences among different enterprises,we identify the"domestic and international circulation separation"pain points where interactive circulation continuously de-clines as domestic large circulation promotes value chain extension.We explore paths to coordinate the extension of do-mestic and interactive circulation,enriching theoretical understanding and practical solutions for enterprise value chain changes under the new pattern of development.In summary,this paper not only expands the theoretical research outcomes on value chain length and broadens the boundaries of dual circulation studies but also provides policy insights and decision-making references on how to enhance interactive circulation levels and build autonomous and efficient industrial chains under the new pattern of development.
