Common prosperity level evaluation: A comprehensive method based on probabilistic linguistic ordered weighted...

Area of Science:

• Socio-economic development
• Regional economic analysis
• Public policy evaluation

Background:

• Common prosperity is a key national initiative in China.
• Scientific measurement and evaluation of common prosperity are critical for policy implementation.
• Existing evaluation methods may not fully capture the complexity and uncertainty inherent in assessing common prosperity.

Purpose of the Study:

• To construct a comprehensive evaluation index system for the common prosperity level (CPL).
• To develop an advanced evaluation model for CPL using prospect theory and probabilistic linguistic methods.
• To apply and validate the proposed framework using data from Zhejiang Province, a common prosperity demonstration zone.

Main Methods:

• Development of a Probabilistic Linguistic Term Set (PLTS) to handle uncertainty in assessments.
• Integration of prospect theory to incorporate expert preferences.
• Application of the TOPSIS method combined with a probabilistic linguistic ordered weighted distance measure.
• Empirical evaluation using data from Zhejiang Province.

Main Results:

• The proposed PLTS evaluation framework demonstrates robustness in assessing the common prosperity level (CPL).
• Sensitivity and comparative analyses confirm the effectiveness and advantages of the developed evaluation model.
• The study provides a validated approach for measuring progress towards common prosperity.

Conclusions:

• The novel PLTS-based evaluation framework is effective for measuring common prosperity.
• The study provides a robust methodology for future common prosperity assessments.
• Specific recommendations are proposed to enhance common prosperity development based on the findings.
