中国公路资本存量测算(1952-2009)

资本存量数据是进行宏观经济分析的核心变量之一，同时也是资产负债核算的重要内容. 目前，经济学界对我国资本存量估算的研究工作已有不少积累，但并没有对公路进行过单独研究和测算. 1998年以来的大规模公路建设投资形成了庞大的公共基础设施，为我国社会经济奠定了重要的发展基础，因此，无论是立足于全社会还是交通行业自身，都很有必要采用资本存量的概念对我国公路资产进行准确度量. 本文基于国际通用的永续盘存法（PIM）探讨公路资本存量测算的若干技术问题，首次采用分解加权法计算了我国的公路资产折旧率，并对1952-2009年我国公路资本存量进行了系统测算. 不仅在数据上为相关分析提供支撑，同时在方法上可为其他单项资产的资本存量测算提供借鉴.

Measurement of Highway Capital Stock in China:1952-2009

Capital stock is one of the key indices for macroeconomic analysis and always is measured within the national wealth accounts. Although economists have gathered some experiences in the field of capital stock measurements, no one measures highway capital stock as an independent asset. Since 1998, large investments have formed into a huge public asset of the extensive highway system, and it contributed much to the economic development in China. Therefore, it is very necessary to measure the scale of highway system using this useful index. This study investigates several technical problems on measurement of highway capital stock based on the perpetual inventory method (PIM), adopts the disaggregated and weighted method to calculate the depreciation rate, and then measures the highway capital stock in China from 1952 to 2009. The findings and results may provide useful data to relevant research, and the proposed method can also be used for other fixed assets.
