Can income growth and environmental improvements go hand in hand? An empirical study of Chinese agriculture

Abstract

Advancing agricultural carbon emission efficiency and farmers' income simultaneously is crucial for the sustainable progress of agriculture. Our study centered on 31 provinces and cities in China and investigated regional variances and the dynamic evolution aspects of coordinated development in farmers' income and agricultural carbon emission efficiency, utilising panel data from 2005 to 2021. The analysis revealed the following trends: Firstly, China's overall agricultural carbon emission efficiency was steadily increasing, mainly because of technological advancements. Secondly, the correlation between farmers' income and agricultural carbon emission efficiency in China had notably improved from 0.318 to 0.775. Throughout the observation period, disparities in the levels of coordinated development were observed in various provinces with a diminishing fluctuation, indicating regional disparities as the primary instigator. Thirdly, the level of coordinated development highlighted positive clustering attributes, demonstrating an 'east high, west low' pattern; the evolution of coordinated development levels exhibited stability in maintaining the current status. This study holds significant value for developing countries in enhancing farmers' income and agricultural carbon emission efficiency in a coordinated manner.
