ON THE PLAUSIBILITY OF THE SUPPLY‐DRIVEN INPUT‐OUTPUT MODEL: EMPIRICAL EVIDENCE ON JOINT STABILITY*
从经验角度检验供给驱动型投入产出模型的合理性，认为在应用中要求生产系数完全固定过于严格，模拟显示系数变化在常规容忍范围内。
ABSTRACT. This paper addresses the issue of the plausibility of the supply‐driven input‐output model from an empirical standpoint. We suggest that requiring production coefficients to remain perfectly fixed during an application of the supply‐driven input‐output model is unnecessarily restrictive given the extensive use of approximation methods in mathematics, economics and regional science. Simulations with the supply‐driven version of an input‐output table for a representative region are shown to result in changes in the corresponding production coefficients well within conventional tolerance levels.
