Abstract
Data on physical capital are an indispensable part of economic growth and efficiency studies. In the case of China, fixed asset time series are usually derived either by aggregating gross fixed capital formation data over time, net of depreciation, or by correcting the limited official fixed asset data available. These procedures, to varying degrees, ignore that (i) gross fixed capital formation does not equal investment, (ii) investment does not equal the value of fixed assets newly created through investment, (iii) depreciation is an accounting measure that has no impact on changes in the production capacity of fixed assets, (iv) official fixed asset data, where available, incorporate significant revaluations in the 1990s, and (v) the variable 'net fixed assets,' frequently used in the literature, is an inappropriate measure of fixed assets for the purpose of growth or efficiency studies. This paper derives economy-wide fixed asset values for 1954-2002, correcting for these shortcomings. It also uses the so far unexplored method of combining economy-wide depreciation data (in the income approach to the calculation of gross domestic product) with an economy-wide depreciation rate to directly yield economy-wide fixed assets. The fixed asset time series derived here are contrasted with each other as well as with those presented in the literature. The reliability of the different series is evaluated, leading to the recommendation of a specific choice of fixed asset time series.Capital, fixed assets, investment, national income accounting, production function estimations, measurement of economic growth, Chinese statistics
