城市迂回生产与城乡共同富裕

Urban Roundabout Production and Urban-Rural Common Prosperity

需求与供给的相互决定暗含了迂回生产水平决定生产力水平和收入水平,从而进一步决定共同富裕程度,而共同富裕程度决定的市场规模又反过来决定迂回生产水平。基于2003—2014年城市级别数据并将共同富裕纳入斯密-杨格定理的实证研究表明:第一,生产链长度增加带来的城市迂回生产水平提升对实现城乡共同富裕具有重要促进作用;第二,在城市迂回生产推动城乡共同富裕的过程中,城市迂回生产会对农村居民收入增长产生更大的促进作用,从而避免了城乡收入差距的快速扩大,并且城市迂回生产还会通过促进全要素生产率增长进而推动城乡共同富裕;第三,考察城市迂回生产的分工深化趋势的影响后发现,嵌入全球分工不仅能够促进城市富裕程度的提升,还能够有效促进城乡收入差距的缩小。上述结果意味着,如果要从生产分工的角度来助力实现城乡共同富裕,就需要鼓励城市积极嵌入生产链进行协同分工,特别是保持高水平对外开放、嵌入全球价值链分工。

The mutual determination of demand and supply implies that the level of roundabout production determines the level of productivity and the income level,thus determines the level of common prosperity,and the market size determined by the degree of common prosperity in turn determines the level of roundabout production.Based on the data of Chinese cities from 2003 to 2014,this paper conducts an empirical study by integrating common prosperity into the Smith-Younger theorem.The findings show that,firstly,the improvement of the urban roundabout production brought about by the increase in the length of the production chain has a great promoting effect on the realization of urban-rural common prosperity.Secondly,in the process of the urban roundabout production promoting the urban-rural common prosperity,the urban roundabout production has a greater improving effect on the income growth of rural residents,thus effectively avoids the fast expansion of the urban-rural income gap;besides,the urban roundabout production also promotes the urban-rural common prosperity through the promotion of the growth of total factor productivity.Thirdly,by examining the impact of the trend of the urban roundabout production,namely,the deepening of the division of labor,it is found that the embedding in global division of labor can not only promote the improvement of the degree of urban prosperity,but also effectively narrow the urban-rural income gap.The above results indicate that,to realize the urban-rural common prosperity from the perspective of division of labor,it is necessary to accelerate the integration of cities into the production chain for the coordinated division of labor,especially to maintain high-level opening-up and participate in the global division of labor.
