摘要
“一带一路”沿线国家的共同低碳转型对于全球应对气候变化意义重大,考察沿线国家碳强度收敛特征,并分析与中国开展经贸合作是否可以促进其碳强度收敛速度,对于客观评价中国在促进绿色“一带一路”建设中的作用具有重要意义。本文基于2003—2018年87个国家数据,运用包含空间效应的绝对和条件β收敛模型,从整体以及区域层面分析与中国开展投资和贸易合作对沿线国家碳强度收敛速度的影响。研究表明:(1)从整体层面来看,“一带一路”沿线国家碳强度存在空间β收敛趋势,并且条件β收敛速度大于绝对β收敛速度,反映了与中国开展经贸合作能够明显加速碳强度收敛。(2)从大洲层面来看,与中国开展经贸合作均对碳强度收敛速度起到促进作用。其中,对非洲地区的促进作用最大,其次是亚洲和拉丁美洲,最后是欧洲。(3)从大洲内部来看,与中国开展经贸合作对非洲撒哈拉沙漠以北地区碳强度收敛的促进作用大于以南地区;对亚洲各区域碳强度收敛的促进作用由大到小依次为中亚、西亚、南亚、东亚及东南亚。因此,“一带一路”沿线国家应加强区域交流沟通,共同应对气候变化,尤其是结合自身发展特点,深化与中国的经贸合作关系,有利于早日共同实现低碳转型。
The common low-carbon transformation in the Belt and Road(BR) countries is crucial to global climate change mitigation. It is of great significance to examine carbon intensity convergence in the BR countries and analyze the impact of investment and trade cooperation with China on carbon intensity convergence for evaluating China’s role in promoting the construction of the green BR. Based on the panel data of 87 BR countries from 2003 to 2018, this study established absolute and conditional β convergence models including spatial effects to analyze the carbon intensity convergence considering the investment and trade cooperation between China and the BR countries. The empirical results show that:(1) There are spatial autocorrelation and convergence of carbon intensity in the BR countries. The investment and trade cooperation between China and the BR countries has a positive influence on carbon intensity convergence.(2)The investment and trade cooperation between China and the BR countries has different effects on the improvement of carbon intensity convergence rate in different continents. The degree of improvement in Africa is greater than Asia, followed by Latin America. The degree of carbon intensity convergence improvement is minimal in Europe.(3) In different parts of the same continent, the investment and trade cooperation also have different effects on the improvement of carbon intensity convergence rate. In Africa, the whole continent is divided by the Sahara. The increase of convergence rate of carbon intensity in the areas north of the Sahara is faster than that to the south. In Asia, as far as the growth rate of carbon intensity convergence is concerned, Central Asia is most affected, followed by West Asia, South Asia, East Asia and Southeast Asia. Therefore,the BR countries should enhance communication to address climate change together. In particular,these countries can deepen the investment and trade cooperation relationship with China based on their own development characteristics, which is conduc
