Abstract

The study constructs a comprehensive benefit evaluation system for biobanks based on cost-benefit analysis, aiming to provide decision support for the scientific management of biobanks and the effective utilization of national strategic resources. By using the grounded theory method, key concepts are extracted, with two core categories of cost and benefit identified. A comprehensive benefit evaluation indicator system is constructed, including construction and operation costs, regulatory costs, strategic benefits, scientific benefits, economic benefits, and social benefits. The cost-benefit analysis method is used to construct an evaluation model. The Germplasm Bank of Wild Species in China is empirically studied as a case study to comprehensively evaluate its performance in key dimensions of cost and benefit. Using the Monte Carlo simulation, the development trend of the Germplasm Bank of Wild Species is predicted for 2035 and 2050. The results show that the biobank has achieved significant results in preservation, scientific research, and talent cultivation, and has made important contributions to biodiversity conservation and sustainable development. However, the biobank still has shortcomings in terms of preservation gains, external scientific benefits, achievement transformation, and market-oriented commercialization. It is necessary to optimize the cost structure and continue to explore its scientific and economic benefits. The evaluation system of this study provides a scientific and comprehensive tool for the comprehensive benefit evaluation of biobanks, and offers important decision support for the construction and management of biobanks.
