- Diversity index is an indicator to study the comprehensive development degree of a country, region or city. Including the original diversification index and precise diversification index.
- The calculation formula is as shown on the right.
- The original diversification index is inversely proportional to the degree of comprehensive development.
- Where x1 is the original diversification index, y1, y2 ... yn are the proportion of output value of each industrial sector, and y1> y2> y3> ...> yn, y1 + y2 + ... + yn = 100%;
- The precision diversification index is directly proportional to the degree of comprehensive development. The calculation formula is:
- x2 = (x1-x0) / (xmax-x0)
- Where x2 is the precise diversification index and x2 is the actual minimum original diversification index. Assuming that the national or regional industrial development is the most comprehensive, the original diversification index calculated based on the national or regional industrial structure is the smallest original diversification index. xmax is the theoretical maximum original diversity index. When there is only one industrial sector in a region, the original diversification index value is the largest. That is: xmax = y1 × n, y1 = 100, n is the number of industrial sectors. The diversity index is used to reflect the comprehensive development of a country, a region or a city. When the industrial development in a certain area is relatively single, the value of the precision diversification index is higher; when the development of various industrial sectors in a certain area is more balanced, the value of the precision diversification index is lower.
