Table 1: Indicators after Delphi questionnaire. of voting. Following the completion of the second round, a consensus was reached among the experts, and no third round of survey testing was conducted. Both rounds of the survey achieved a 100% response rate. The Delphi survey data are shown in Table 2.  
Ultimately, after two rounds of the Delphi survey and subsequent analysis, the indicators obtained are as shown in Table 3.
