摘　　要：构建兼具生产和财富属性的资本核算框架,全面测度1981—2022年全国层面以及1996—2022年省级层面农村基础设施资本存量并作敏感性分析,在此基础上对其空间差异和动态演进特征展开探究。研究发现:资本存量测度结果对钟形退役模式下正态分布形式的设定不敏感,而役龄—效率函数形式的差异会显著影响测度结果;农村基础设施资本存量不断攀升,财富性资本存量净额、生产性资本存量和财富性资本存量总额依次递增;农村基础设施的总体差异呈现“U”形演变趋势,西部地区不存在σ收敛,全国、各区域、各阶段均呈现β收敛特征,收敛速度存在明显时空异质性。The paper firstly constructed a capital accounting framework encompassing both production and wealth attributes,and comprehensively measured China’s rural infrastructure capital stock at the national level from 1981 to 2022 and at the provincial level from 1996 to 2022,followed by sensitivity analyses.On this basis,the paper further explored relevant spatial differences and dynamic evolution.The research findings indicated that,the measurement results were not sensitive to the specification of the normal distribution form under the bell-shaped retirement model,while the difference in the age-efficiency function form significantly affected the measurement outcomes.The rural infrastructure capital stock has been steadily increasing,with the net amount of wealth-related capital stock,productive capital stock,and total wealth-related capital stock rising sequentially.The overall disparities in rural infrastructure exhibited an“U”-shaped evolutionary trend.The rural infrastructure had noσconvergence in the western region,but had theβconvergence characteristic at the national,regional,and stage levels.In addition,the convergence rate had significant patial and temporal heterogeneity.
