我国省际总资本存量和净资本存量估算研究

A Study on the Estimation ofChina’s Interprovincial Total Capital Stock and Net Capital Stock

总资本存量是估算净资本存量的起点,是研究全要素生产率的基础,但以往文献对省际总资本存量的估算研究较为少见。在梳理了总资本存量与净资本存量、经济折旧与会计折旧的联系和区别,明确了资本存量估算中残存模式和价值模式之后,理清了省际总资本存量和净资本存量的估算思路,并通过结构系数将估算出的省际层面资本存量数据与国家层面数据进行了有效衔接。与已有研究中净资本存量的估算结果对比表明:国家层面和省际层面上的净资本存量都与已往研究中的结果较为接近。因此,利用较易获取的会计折旧数据及适当的估算方法所估算出的省际总资本存量也是可靠的。

Total capital stock is the starting point for net capital stock,and it is the basis for the study of total factor productivity,but literature on estimating the interprovincial total capital stock is very limited.This paper sorts out the connections and differences between total capital stock and net capital stock,as well as between economic depreciation and accounting depreciation.It clarifies the residual models and the value models in capital stock estimation,and then provides estimation ideas for the interprovincial total capital stock and net capital stock.In this paper,the estimated inter-provincial capital stock data is effectively linked to national-level data through structural coefficients.Comparison with the estimated results of the net capital stock in existing studies shows that the net capital stocks at both national and interprovincial levels in the present study are rather close to the results in previous studies.Therefore,it is a reliable method to estimate the interprovincial total capital stock by using more readily available accounting depreciation data and appropriate estimation methods.
