数字新质生产力、农业产业链延伸与共同富裕

Digital New Quality Productivity,Extension of Agricultural Industry Chain and Common Prosperity

文章以2011-2022年作为考察区间,选取中国273个地级及以上城市的面板数据,实证检验数字新质生产力对共同富裕的影响效应及作用机制。研究结果表明,数字新质生产力能显著推进共同富裕。异质性分析结果表明,数字新质生产力对长三角、珠三角、京津冀城市群及大规模城市共同富裕的推动作用更强;机制检验结果表明,数字新质生产力能够通过农业产业链延伸助推共同富裕,农业产业链延伸在数字新质生产力与共同富裕的关系中起到部分中介作用;门槛回归结果表明,在全国及东部地区,数字新质生产力对共同富裕呈现边际效益递增的非线性动态影响;而在中部地区及西部地区,则呈现正向“N”型非线性影响。

Taking the years from 2011 to 2022 as the investigation interval,this paper selects the panel data of 273 prefecture-level and above cities in China to empirically test the impact and mechanism of digital new quality productivity on common prosperity.The research results show that digital new quality productivity can significantly promote common prosperity.The heterogeneity analysis results show that the digital new productivity plays a stronger role in promoting the common prosperity of the Yangtze River Delta,the Pearl River Delta,the Beijing-Tianjin-Hebei urban agglomeration and large-scale cities.The results of the mechanism test show that digital new quality productivity can promote common prosperity through the extension of the agricultural industrial chain,and the extension of the agricultural industrial chain plays a partial intermediary role in the relationship between digital new quality productivity and common prosperity.Threshold regression results show that in the whole country and the eastern region,digital new quality productivity has a nonlinear dynamic effect of increasing marginal benefit on common prosperity,while in the central and western regions,it shows a positive N-type nonlinear impact.
