Abstract: It is of great significance to clarify the decoupling relationship among resource consumption, environmental pollution, and economic growth, and to uncover the driving mechanism within the relationship for Fujian Province, one of the national ecological civilization construction demonstration zones. By constructing the “water-energy-carbon” resource and environment input-output model, we analyzed the industrial “water-energy-carbon” resource and environment pressure in Fujian Province. On the basis of the decoupling theory and Logarithmic Mean Divisia Index method, we explored the decoupling among resource consumption, environmental pollution, and economic growth and detected driving factors behind the decoupling state in various industries. The results showed that resource and environmental pressure state dominated by virtual water in Fujian Province had shifted to the multi-dimensional resource and environmental pressure state dominated by implied carbon from 2002 to 2017. There were distinctive differences among various industries. From the perspective of industry sectors, there was a relatively high direct resource and environmental pressure in the production and supply sector, as well as a more distinguishing indirect resource and environmental pressure in the manufacturing sector. The decoupling state generally appeared reasonable, mainly in weak decoupling and strong decoupling states. The economic and population effects were the two main factors inhibiting the decoupling sate, while the technical and structural effects promoted the decoupling state.

Key words: decoupling, input-output model of resources and environment, logarithmic mean Divisia index method (LMDI).
