环境规制下“内循环”产能模式对中国制造业出口产品质量的影响研究

Research on the Influence of“Inner Cycle”Capacity on Export Quality of China's Manufacturing Products under Environmental Regulation

面对国际市场竞争、经济结构转型和环境可持续发展的新时期发展特征,中国工业如何实现出口产品由“量”向“质”稳步转变成为了亟待解决的重要问题。为此,文章在产能协调理论和高质量发展理念的基础上,构建均衡数量模型刻画“内循环”产能模式内涵,以及出口产品质量影响机制,并在此基础上采用门槛模型检验2010—2020年环境规制下“内循环”产能与制造业出口产品质量的关系。研究发现,第一,在遵循环境规制要求的前提条件下,“内循环”产能模式对制造业出口质量具有推进效应,但地区“内循环”产能模式存在阶段性发展过程。第二,科技创新虽然能够优化“内循环”产能模式中产能质量和产能规模的均衡关系,实现出口产品质量的持续优化,但生产资本分配特征和地区经济偏好仍是“内循环”产能模式的质量要素优化的主要制约因素。第三,环境规制、交通基础设施建设和数字赋能能够有效加速“内循环”产能模式的产品质量优化进程,避免产能质量与产能规模结构失衡。文章为中国制造业实现出口产品质量持续优化提供理论和经验证据,加强政府对市场资源规划和宏观调控政策制定的认识。

Relying on the important strategic deployment of“the new development pattern of domestic large circulation as the main body and domestic and international double circulation promoting each other”,how to optimize the quality of export products in the manufacturing industry by changing the production capacity model is particularly important.At the same time,different from the traditional economic transformation,the“inner cycle”production capacity model and the quality of manufacturing export products must not only meet the needs of economic interests,but also always maintain the development needs of environmental sustainability.Therefore,this paper introduces environmental regulation as an external control framework to further improve the“internal circulation”production capacity model and the environmental sustainability of manufacturing export product quality.Based on the theory of production capacity coordination and the concept of high-quality development,this paper constructs an equilibrium quantity model to describe the connotation of“internal circulation”production capacity model and the influence mechanism of export product quality.On this basis,a threshold model is adopted to test the relationship between“internal circulation”production capacity and the quality of manufacturing export products under environmental regulations from 2010 to 2020.The research finds that,first,under the precondition of complying with environmental regulations,the“internal circulation”capacity model has a promoting effect on the export quality of manufacturing industry,but the regional“internal circulation”capacity model has a phased development process.Second,although scientific and technological innovation can optimize the equilibrium relationship between capacity quality and capacity scale in the“inner cycle”production capacity model and achieve continuous optimization of the quality of export products,the characteristics of production capital distribution and regional economic preferences are still the main constraints on the optimization of quality factors in the“inner cycle”production capacity model.Environmental regulation,transportation infrastructure and digital empowerment can effectively accelerate the product quality optimization process of the“inner cycle”capacity model,and avoid the structural imbalance between capacity quality and capacity scale.Compared with the traditional research on production capacity and manufacturing export product quality,the main contributions of this paper are as follows:First,on the basis of building a quantitative model to establish the connotation of“inner cycle”production capacity model,this study enriches the theoretical content and empirical results of“inner cycle”production capacity model on manufacturing export product quality,and provides a more comprehensive basis for manufacturing production capacity transformation strategy.Second,based on the conclusion of the literature study on the cost of environmental regulation,this paper introduces environmental regulation into mathematics,and further reviews the impact mechanism of environmental regulation on the quality of export products and the“internal circulation”production capacity model.Finally,although the mathematical model and theoretical mechanism can better present the impact of various factors in the“inner cycle”production capacity model on the quality of manufacturing export products.But this does not mean that the link between the three elements is unimpeded.Based on this,on the basis of the main research content,this paper derived research on the theoretical mechanism of the interactive effect of transportation infrastructure,digital empowerment and“inner cycle”productivity,to fill the lack of research on the link relationship of relevant factors.
