Meeting investors’ demands in PPP project to improve enthusiasm for participating in green and low-carbon

The use of PPP scheme to guide private investors to actively participate in green and low-carbon development is conducive to filling the funding gap of domestic green and low-carbon transformation. It is important to meet the demands of investors to ensure that investors can permanently participate in PPP low-carbon projects. Due to the high financing leverage, wide coverage, and government's right to initiate in PPP project, the investors' demands also include the enhancement of social reputation, and the acquisition of future project market resources besides investment income. To fully understand the purpose of the investors' participation in PPP projects and provide guidance for further analysis of behavioural influence path, the study systematically analyzes the demands of investors and develops a demand measurement scale. Firstly, based on the characteristics of PPP scheme, six investor's demands were identified. Secondly, through theoretical analysis, the measurement items of investors' demand were constructed, and 269 valid data were collected through questionnaire. Finally, carrying out factor analysis, reliability and validity test, the items were revised to get the formal investor demand scale. The research provides guidance for improving the demand satisfaction of investors, which is conducive to attracting private capital to participate in the green low-carbon development strategy of PPP projects, and provides financial guarantee for achieving the ‘double carbon’ goal.
