Abstract:

Two common characters can be found in the changes of investment and consumption rates across the world: 1. The investment rate will rise along with the advancing of industrialization and with the growing share of added value in GDP whereas the consumption rate will decline in the same context; 2. The investment rate shows cyclical fluctuation around the development trend. However there are great differences in the investment and consumption rates and wavelength of cyclical fluctuation in various countries. No common rates or fixed fluctuation periods can be observed among the countries even in the same development stage.
