Method for determining matching relationship between water resources and social economy based on rank difference

Abstract

The invention provides a method for determining a matching relationship between water resources and social economy based on rank difference, and the method comprises the steps: determining a to-be-studied water resource quantity and a social economy index, and obtaining a rank corresponding to a water resource quantity sequence and a rank corresponding to a social economy index sequence; establishing a rank difference degree calculation function of the water resource quantity and the social and economic indexes; according to a traditional Gini coefficient calculation formula, determining a numerical value difference degree between the water resource quantity and the social economic index; establishing a rank Gini coefficient calculation function according to the rank difference degree and the numerical value difference degree, and calculating the rank Gini coefficient of the research region by the calculation function; and establishing a matching relationship between the rank Gini coefficient and the water resource quantity and the social economic index to determine the matching degree of the water resource quantity and the social economic index of the research region. According to the method, the matching relationship between the utilization condition of the water resource and the social economic development level can be quantitatively analyzed, and the information loss caused when the traditional Gini coefficient is converted from a high dimension to a low dimension can be made up.

Description

technical field [0001] The invention belongs to the technical field of social development and social services, and specifically relates to a method for determining the matching relationship between water resources and social economy based on rank differences. Background technique [0002] As a natural resource, water resources play an irreplaceable role in material circulation, energy transportation and information transmission; in human society, water resources support the development of social economy and belong to a strategic economic resource . It is generally believed that the matching between water resources and social economy refers to the positive or negative correlation between the two. For example, in areas with poor water resources, the social economy is backward; in areas with rich water resources, the social economy is developed. Water resources are the basic resources of social and economic development, and determine the scale and direction of social and econo...

Problems solved by technology

This inevitably brings up the problem that sorting has an impact on matching results

Secondly, the calculation of the Gini coefficient is a process of transforming high-dimensional data into one-dimensional data, and there is inevitably the problem of missing information. Finally, the original Gini coefficient only describes the characteristics of the overall mismatch and cannot be compared with the Lorenz curve. one-to-one correspondence
