工业生产指数编制方法的优化建议

工业生产指数是反映工业发展速度的通用方法。其编制的关键要素有两个：其一是代表性产品的个体物量指数；其二是工业增加值权数。指数的实效性较强，但其编制方法本身也有不完善之处。其优化方法可以从其编制要素的修正来进行。其中对个体物量指数的修正，就是对每种代表品的增加值指数的修正。对原权数进行修正，是假设在基期产量不变的条件下，单位代表产品的基期增加值可用报告期代表产品平均单位增加值代替。通过计算修正系数，对个体物量指数和权数进行修正后，可得出较贴近实际的工业生产指数。

The Proposal of Index Number of Industrial Production's Optimum Method of Establishment

Index number of industrial production is the general method that reflects industry speed of development.The key factor of his establishment has two: One is single quantity index of representativeness product; Another is the weight of industry value added. Actual effect of index is stronger, but his establishment method itself cannot not have perfect(ly) the part yet. His optimum method can be come to be in progress from the correction of his establishment key factor. The correction of single quantity index is the correction of the value added index of each representative products.Revise to primary weight Being the hypothesis in base period under the unchangeable condition of base output,the added value of base period of the unit represents can be replaced by average unit added value of current product of represent . By way of counting to revise the coefficient, after to single quantity index is revised with the flexible strategy can reach to approach the real industry production index.
