灰色地区间投入产出分析方法探讨

Grey Interregional Input-Output Analysis

由于各区域间的经济关系特别复杂,因此在运用地区间投入产出分析方法解决实际问题时很难以获得各部门统计数据的精确值。文章采用灰色计算方法提出了灰色地区间投入产出分析。该方法可以使决策者得到直接消耗系数的有效范围,即当统计数据值不精确时也可以实现对地区间的经济关系进行分析和控制。模拟案例验证了该方法的有效性。

Because the relationship between the regional economies is very complex, it is impossible to get the exact value of statistic datum when we utilize the interregional inpnt-out analysis. On the basis of grey computation, we proposed grey interregional input-output analysis. The decision-makers can get the ranges of direct consumption coefficients, and the interregional economies are controlled even if the statistic datum is uncertain. The modified case verifies the effectiveness of our method.
