After the server 104 receives the longitude and latitude data and power consumption data of each sub-area in the target area, the server 104 constructs a power consumption gravity center identification model for the longitude and latitude data and power consumption data of each sub-area in the target area; according to the longitude and latitude data and power consumption data of each sub-area, the power consumption gravity center coefficient between any two sub-areas in the target area is obtained by using the power consumption gravity center identification model, and a power consumption gravity center coefficient matrix is formed; the power consumption gravity center coefficient in the power consumption gravity center coefficient matrix is binarized; according to the binarized power consumption gravity center coefficient matrix, the center of gravity index of each sub-area in the target area for the target industry is calculated by using the centrality analysis method; the sub-area with the largest gravity center index is selected as the gravity center area of the target industry in the target area. The server 104 can feed back the obtained center of gravity area of the target industry in the target area to the terminal 102. In addition, in some embodiments, the regional industry center of gravity positioning method can also be implemented by the server 104 or the terminal 102 alone, such as the terminal 102 can directly perform regional industry center of gravity positioning for the longitude and latitude data and power consumption data of each sub-area in the target area, or the server 104 can obtain the longitude and latitude data and power consumption data of each sub-area in the target area from the data storage system, and perform regional industry center of gravity positioning for the longitude and latitude data and power consumption data of each sub-area in the target area.

The method is executed by a computer device, and can be executed by a computer device such as a terminal or a server alone, or by a terminal and a server together. In the embodiment of the present application, the method is applied to Figure 1 The server 104 in the example is used for explanation, and the steps include the following steps 201 to 206.
[0033] Step 201: Collect the longitude and latitude data and power consumption data of each sub-area in the target area.
[0034] Step 202: Construct a power consumption center of gravity identification model.

[0039] The implementation of steps 201 to 206 above aims to solve the problem of difficulty in locating the center of gravity of the industry. Electricity consumption shows a certain degree of correlation in space. This correlation is reflected in the present application in that electricity consumption in the center of gravity of the industry has a large spillover effect on other regions. Electricity consumption data can reflect the electricity consumption of sub-regions and is an important basis for judging the competitiveness of urban industries. Therefore, analyzing the spillover effects between sub-regions based on electricity consumption data can reflect the center of gravity of the industry in a certain area. By analyzing the spillover effects of each sub-region on other sub-regions in industrial development, the center of gravity of industrial development is located to promote coordinated development between sub-regions.

Since the remote geographical location will have a negative impact on the centrality of the sub-region, the inverse of the geographical distance is introduced.

[0047] In another exemplary embodiment of the present application, the power consumption gravity center coefficient is binarized so that the same scale range can be used in the subsequent centrality analysis method to calculate the degree centrality, closeness centrality and betweenness centrality. The binarized power consumption gravity center coefficient matrix is used as the basis for identifying the industry gravity center. Then the above step 204 can be replaced by the following steps 301 to 302.
[0048] Step 301: If the power consumption gravity center coefficient is greater than or equal to the average value of the power consumption gravity center coefficients in the power consumption gravity center coefficient matrix, the power consumption gravity center coefficient is set to 1.
[0049] Step 302: If the power consumption gravity center coefficient is less than the average value of the power consumption gravity center coefficients in the power consumption gravity center coefficient matrix, the power consumption gravity center coefficient is set to 0.
[0050] In another exemplary embodiment of the present application, the core indicators of the centrality analysis method are comprehensively considered to identify the location of the industrial center of gravity area. The above step 205 can be replaced by the following steps 401 to 404.
[0051] Step 401: Based on the binarized power consumption gravity center coefficient matrix, each sub-region is used as a node, and two nodes whose binarized power consumption gravity center coefficient is 1 are directly connected to form a target area network; wherein the distance between two directly connected nodes is 1.
[0052] Step 402: According to the target area network, the degree centrality, closeness centrality and betweenness centrality of each sub-area are calculated respectively.
[0053] Exemplarily, the calculation formula of degree centrality is as follows: .
[0054] In the formula, For sub-region The degree centrality of For sub-region The number of directly connected sub-regions; is the total number of sub-regions in the target region.
[0055] The calculation formula for closeness centrality is as follows: .

[0061] Step 403: Normalize the betweenness centrality of each sub-region.
[0062] Step 404: The sum of the degree centrality, closeness centrality and normalized betweenness centrality of each sub-region is determined as the center of gravity index of each sub-region for the target industry.
[0063] .
[0064] In the formula, For sub-region Center of gravity index for target industries.
[0065] In another exemplary embodiment of the present application, when each sub-region in the target region is a city, the present application uses the centrality analysis method to first collect the latitude and longitude data and electricity consumption data of each city in the target region; secondly, calculate the industrial power consumption center of gravity identification coefficient to compare the industrial center of gravity bias between cities; furthermore, binarize the calculation results; finally, identify the industrial center of gravity city through centrality analysis. The present application can not only improve the accuracy and real-time performance of identification, but also provide strong data support for industrial policy formulation and regional development.
[0066] This application uses electricity consumption data and centrality analysis methods to analyze electricity consumption data to understand the electricity consumption patterns and spillovers in industrial core areas, helping regional planners identify industrial core areas within the region, thereby optimizing resource allocation and improving the level of coordinated development between sub-regions within the target region. In addition, electricity consumption data reflects the electricity consumption of sub-regions, providing decision support for the power industry.
[0067] Furthermore, the method of the present application can also predict electricity demand, optimize electricity resource allocation, and improve electricity supply efficiency.
