An Economic Analysis of Biproportional Properties in an Input‐Output System
研究了1980-1997年芝加哥地区投入产出系数的时序变化，通过计量经济分析判断系数是否具有稳定性或可预测变化，为投入产出表的时间序列生成方法提供依据。
Various methods, such as biproportional adjustment and econometric estimating have been used to generate time series for input‐output tables. In this paper, temporal changes of input‐output coefficients are examined in order to analyze their behavior. Within the Chicago Region Econometric Input‐Output Model, a set of input‐ output relationships has been extracted analytically for the period 1980–1997. Using the empirical evidence for Chicago, this paper conducts econometric time series analysis to determine whether or not certain coefficients or sets of coefficients exhibit tendencies toward stability or predictable change or whether others require more extensive econometric estimation.
