工业结构变动率计算方法探讨
目前，工业结构变动率的计算方法主要有两种：绝对变动率和平均偏差变动率。我们认为前者直观简单，但不能体现行业自身变动的大小；后者能反映行业自身变动的大小，但忽略了大行业与小行业之间的差别。为此，本文提出了两种改进的方法：加权平均偏差变动率和修正加权平均偏差变动率，并以实例进行了分析比较。
Discussion on Computing Methods for Industrial Structure Change Rate
At present, Industrial structure change can be arrived at mainly by two means: absolute change rate and average deviation change rate. The absolute change rate is straightforward and simple, but it can not reflect the extent of change the industry experiences; the average deviation change rate can reflect the extent of change the industry experiences, but fails to capture the differences between major and minor sectors. Therefore, the paper makes a few improvements to average deviation change rate, proposing the weighted average deviation change rate and calibrated average deviation change rate. Moreover, the paper provides an example for analysis and comparison.
