Economic evaluation of forestry industry based on ecosystem coupling

The relationship between forest ecosystems and the forestry industry requires a balance between the needs of forestry development and the development of natural ecosystems, which is the core issue of sustainable international economy development. In this paper, the forestry industry is studied. Based on the establishing of the connection between forest ecology and the forestry industry, an analysis for this relationship in terms of a systems perspective is done by using quantitative methods. Furthermore, the model of forestry industry economic evaluation is established based on the construction of the evaluation index system of forestry industry economic benefits, which is performed by data envelopment analysis (DEA). Finally, we analyze more than a dozen instances in Yichun Forest. Through this case-study analysis, the extent of coupling between systems of forest ecology and forestry industry is examined, and the economic benefit of the forestry industry is evaluated.
