Abstract: Achieving the goal of carbon peaking and carbon neutrality is a significant strategic decision put forward by China in recent years. It is an important objective leading China's green and low-carbon development, which can bring multiple effects, such as improving environmental quality and advancing industries. Taking Yichun, a typical forestry resource-based city in China, as an example, an economic-environment-carbon emission evaluation indicator system was established and the entropy method and a coupling coordination model were used to calculate the coupling coordination relationship between economic development, environmental quality and carbon emission in Yichun from 2010 to 2020. The results showed that the economic development and environmental quality of Yichun showed an upward trend, but the carbon emissions and intensity increased greatly, and the overall development pattern shifted from the economy lagging to the environmental and carbon emissions lagging. The level of coupling coordination in Yichun had been consistently improving, progressing from severe imbalance and declining development to intermediate coordinated development, and the environmental and carbon emission subsystems needed to be strengthened. Finally, suggestions were proposed to achieve the goal of high-quality economic development, focusing on solving outstanding environmental problems, strengthening energy conservation and efficiency and circular economy, vigorously developing the forestry economy and actively exploring innovative mechanisms of carbon sink product value realization.
