## 5 Analysis of Empirical Results
### Analysis of Network Characteristics of Charging Stations in Five Districts of Jinan City  
#### 5.2.1 Network Index Analysis Based on Node Local Structure  
According to the charging station network model and the calculation formula of degree value index obtained in Figure 3, a series of indicators are calculated with the help of ucinet software (v.6.0). The calculation results are shown in the following table. 1. Degree  
In terms of importance, Table 1 lists only the top ten sites in terms of degree value, which are analyzed at the midpoint. The same is true of the following analyses. They are 12, 13, 11, 42, 43, 44, 51, 52, 53, and 59, which, respectively, correspond to the special call car charging station (Jinan Ginza Jiayi Harmony Yidian), Apu Public charging station, Iwei Energy vehicle charging station, special call public charging station, special call public charging station, special call public charging station, special call public charging station, special call public charging station, special call public charging station, special call public charging station, special call public charging station, special call public charging station, special call public charging station. Special electric charging station (Shandong News Building electric vehicle), Yiwei Energy car charging station, Yiwei Energy car public charging station, Yiwei Energy car public charging station, Youke Technology car charging station (Watt Road), and Special electric car charging station (Jinan Ginza Jiayi Harmony Yidian). Terai electric car charging station (Jinan Ginza Jiayi Harmony Yidian) and Aipu public charging station have the highest degree value and are the key core nodes in the network. As can be seen from Table 1, the charging stations with higher degree values are concentrated in Huaiyin District and Lixia District, which generally reflects that these two areas have dense population and good economic development, so the demand for charging stations is higher. Therefore, infrastructure investment in these two areas can be increased to facilitate the travel convenience of users. 2. Degree centrality  
From the perspective of new energy vehicle charging stations, \"degree centrality\" represents the general coverage of infrastructure, which reflects the construction degree of charging stations and the distribution of charging points in a region. Table 2 lists the top 10 charging stations for degree centrality. They are 12, 13, 39, 41, 71, 42, 43, 44, 47, and 11, respectively, which correspond to special car charging stations (Jiayi Harmony Yidian in Jinan Ginza), Apu Public charging stations, Youke car charging stations (Watt Road), special car charging stations (Jinan Financial Supermarket), etc. Bus Honglou Charging service station, Special call public charging station, Special call public charging station, Special electric car charging station (Shandong News Building electric vehicle), Iwei Energy car charging station, and Iwei Energy car charging station. The largest degree of centrality is located in Huaiyin District special call car charging station (Jinan Ginza Jiayi Harmony Yidian), indicating that the station occupies an important position in the entire charging station network, as a key facility. It can also be seen that the connectivity is the best in
