Abstract
National key towns are one of the most important units for mitigating China's carbon emissions from urbanisation, industrialisation and agricultural modernisation under China's rural revitalisation strategy. The rise in the carbon footprint (CF) corresponding to increasing populations and energy consumption in national key towns has not been underestimated. This paper aims to explore the impact of local resident energy consumption on the degree of coordination between ecology and the economy. To achieve this objective, the carbon pressure index (CPI), carbon occupancy index (COI) and eco-economic coordination index (EECI) are constructed by applying the CF, carbon carrying capacity (CC) and carbon deficit (CD) of Caijiapo Town from 2012 to 2017. Furthermore, the relationship between the CF, economic growth and per capita disposable income is described based on the decoupling index (DI). The results reveal that, apart from a decline in 2014, the per capita CF of Caijiapo Town has increased, with an average annual growth rate of 16.80%. The CF of different energy sources shows that the CF of natural gas is much larger than those of raw coal, oil and electricity. The DI between GDP, the per capita disposable income of urban and rural residents and the resident energy CF first decreases and then increases. The DI between GDP, the per capita disposable income of urban residents and the resident energy CF is 1.09 and 1.72, and urban residents are the main contributors to the resident energy CF from 2015 to 2017. The CPI and COI show an upward trend, and the eco-economic coordination index (EECI) of Caijiapo Town undergoes a change from poor coordination (grade II) to worst coordination (grade I) from 2012 to 2017. Therefore, the following suggestions are proposed: the CC should be treated as a constraint, energy utilisation should be improved, residents' consumption structure should be optimised, differentiated policies should be implemented for the energy consumption of urban and rural residents and a spatial planning system and operational mechanism should be established that combines multiple regulations into a single regulation.
