Evaluation System of Economic and Social Benefits of Power Grid Investment under the New Development Pattern

This paper examines the evaluation methods and empirical analysis of power grid investment for reducing pollution and carbon emissions. It first builds a comprehensive effect evaluation index system of power grid investment based on literature review and expert consultation, which consists of four primary indicators: economic benefit, social benefit, environmental benefit and technical benefit, and their corresponding secondary indicators. It then uses the comprehensive evaluation method to calculate the comprehensive evaluation value of power grid investment in each area, and divides the evaluation level by the equidistant method according to the value size. Lastly, it evaluates and analyzes the comprehensive effect of power grid investment in each area based on the evaluation results, identifies the strengths and weaknesses of each area, and proposes suggestions for improvement. This paper offers a scientific method and reference for assessing the impact of power grid investment on reducing pollution and carbon emissions, and has certain theoretical and practical significance for advancing the green and low-carbon transformation and high-quality development of power grid investment.
