We use border currency in Shanxi, Chahar and Hebei, Southern Hebei, Shandong and Henan, Beihai currency in Shandong, northeast currency in Northeast China, and peasant currency in Northwest China.

9. Input output ratio refers to the ratio of the total investment of the project to the total instrial added value of the output in the operation life. It is applicable to the economic effect evaluation index of science and technology projects, technological transformation projects and equipment renewal projects. The smaller the value is, the better the economic effect is. When many investment decision-making organizations and decision-makers use "input-output ratio", they understand it as "the ratio of project input capital to output capital, that is, how many units of capital can be proced by one unit of project input". Its quantity is usually expressed in the form of "1 ∶ n". The larger the n value is, the better the economic effect is. According to this understanding, "input-output ratio" is a static index reflecting the economic effect of project investment. However, in actual use, there are the following problems must be defined.
