摘要: Biodiversity plays a vital role in human survival and development. In the context of economic globalization and increasingly serious global biodiversity loss, the division of global biodiversity responsibilities and cross-regional cooperative conservation are important parts of species conservation. In this paper, an environmentally expanded multi-regional input-output analysis model is used to measure biodiversity loss footprint (overall footprint, internal footprint and external footprint), which not only covers the interference within the region, but also traces the influence out of it. In addition, structural path analysis and social network analysis were used to identify the transmission process and divide the biodiversity protection communities in various countries. The results show that: (1) There are significant differences among countries in terms of biodiversity loss footprint. The top five countries in terms of overall biodiversity loss footprint are Indonesia, China, the United States, Mexico and Brazil, but they have different impact modes on biodiversity; (2) While most of the footprint of biodiversity loss occurs within the region, more than a quarter of the footprint is due to global production chains outside the region. The study concluded that through the global production chain, species will eventually be influenced by the United States, Japan, India and China; (3) Among economic sectors, agriculture has the largest direct biodiversity footprint. Food & Beverages sector has the largest indirect biodiversity footprint; (4) Eight biodiversity protection communities have been formed around the world, including source community and mixed community of biodiversity protection, each four. Among them, the source community is represented by Indonesia, India, Australia, the Philippines and Thailand in South and Southeast Asia, while the mixed community is mainly composed of China, Japan, Cameroon and Vietnam in East Asia and South Africa. In order to protect biodiversity effectively, different strategies are proposed for different types of communities.
