服务业开放对制造业价值链攀升效率的影响研究——基于门槛回归的实证分析

A Study on Influence of Service Openness on Climbing Efficiency of Manufacturing Value Chain——An Analysis Based on Threshold Regression

服务业开放带来的知识、技术等在提高制造业价值链攀升效率和推动经济高质量发展上发挥了关键作用。本文利用超效率DEA模型对各地区制造业价值链攀升效率进行评价,并考察了服务业开放与制造业价值链攀升效率的关系。结果表明,服务业开放有利于提高制造业价值链攀升效率。本文进一步分析了人力资本、生产性服务业发展及制度环境在服务业开放对制造业价值链攀升效率影响中的门槛效应。结果显示,人力资本存在显著的单门槛效应,当人力资本水平较低时,服务业开放对制造业价值链攀升效率的影响不显著,随着人力资本水平的提高,服务业开放对制造业价值链攀升效率的影响显著增强;生产性服务发展水平越高,服务业开放提高制造业价值链攀升效率的效应也越强;制度环境存在双门槛效应,当制度环境较差时,服务业开放对制造业价值链攀升效率的影响不显著,随着制度环境的改善,服务业开放对制造业价值链攀升效率的促进效应逐渐增强。

The knowledge and technology brought by service openness play a key role in improving the climbing efficiency of manufacturing value chain and promoting the high quality development of economy. In this paper, the climbing efficiency of manufacturing value chain is evaluated by using the super efficiency DEA model, and the relationship between service openness and the climbing efficiency of manufacturing value chain is investigated. The results show that service openness is beneficial to increasing the climbing efficiency of manufacturing value chain. This paper further analyzes the threshold effect of human capital, producer services development and institutional environment on the effect of service openness on the climbing efficiency of manufacturing value chain. The results show that there is a significant single threshold effect of human capital.When the level of human capital is low, the impact of service openness on the climbing efficiency of manufacturing value chain is not significant, with the improvement of human capital, service openness has greatly increased the effect of the climbing efficiency of manufacturing value chain. The higher the development of producer services, the better the effect of service openness to increase the climbing efficiency of manufacturing value chain. There is a double threshold effect of institutional environment. When the institutional environment is poor, the impact of service openness on the climbing efficiency of manufacturing value chain is not significant, with the improvement of institutional environment, the promotional effect of service openness on the climbing efficiency of manufacturing value chain is increasing gradually.
