Social Impact Assessment of Laos-China Transnational Hydropower Projects in View of the Fuzzy Comprehensive Evaluation
Keywords:Transnational hydropower projects, social impact evaluation, fuzzy comprehensive evaluation, Nanoujiang cascade hydropower station
Having been considered as clean energy, hydropower plays an important role in the energy strategy. Laos is rich in hydropower resources, attracting a large number of Chinese companies to invest in the construction of hydropower stations in Laos. While promoting the economic development of Laos, it also has a non-negligible impact on the regional social system. The objective of this study was to evaluate the social impact of Laos-China transnational hydropower projects which is of great significance for further improving its social benefits and promoting development. This paper constructed a social impact evaluation index for hydropower project investment projects from four aspects: social people’s livelihood, social culture, environment, and the impact of transnational factors on the social system, employing cascade hydropower projects in the Nam Ou river basin in Laos as a sample to conduct empirical analysis. The research results show that the overall evaluation of the Nanoujiang cascade hydropower station on the social impact was at a good level, indicating that it had a great effect on improving the overall social benefits. Among them, the social impact of the project was mainly reflected in social cultural of Laos, with the highest degree. In addition, the impact of the project on the transnational factors in the construction took the second place, and the impact on social environment and livelihood were relatively low.
