参与全球价值链能否推动中国内陆地区产业集群升级

This article analyzes the impact of participating in global value-added trade on the upgrading of industrial clusters in China's inland areas. The empirical results show that: (1) Actively participating in global value-added trade can significantly drive the upgrading of industrial clusters in China's inland areas; however, the intensity of the effect is less than that on the industrial clusters in the eastern region. (2) The trade of raw materials has the greatest facilitating effect on the upgrading of industrial clusters, followed by the trade of producer services, and the promoting effect of the trade of machinery and equipment is the weakest. (3) The upgrading effect of global value-added trade activities with OECD countries on industrial clusters is significantly stronger than that with non-OECD countries. This conclusion holds significantly regardless of whether it is the trade of raw materials, machinery and equipment, or services. (4) The trade of raw materials with Canada has the greatest impact on the upgrading of China's industrial clusters, with an impact of 0.814%; the imports of machinery and equipment and producer services from the United States have the greatest help for the upgrading of China's industrial clusters, with impact coefficients of 0.464% and 0.53% respectively.

本文分析参与全球附加值贸易对我国内陆地区产业集群升级的影响。实证结果表明：（1）主动参与全球附加值贸易，可以显著地带动我国内陆地区的产业集群升级；但是作用强度要小于对东部地区产业集群的影响。（2）原材料贸易对产业集群升级的帮助作用最大，生产性服务贸易的作用次之，机械设备贸易的推动作用最弱。（3）与OECD 国家的全球附加值贸易活动对产业集群的提升作用要明显强于与非OECD 国家。无论是原材料贸易、机械设备贸易还是服务贸易，该结论都显著成立。（4）与加拿大的原材料贸易对我国产业集群升级影响力度最大，为0.814%；从美国的机械设备进口和生产性服务品进口对我国产业集群升级帮助最大，影响系数分别为0.464%和0.53%。
