Abstract: To enhance the development level of low-carbon agricultural economy in China, the entropy method was used to evaluate the development level of low-carbon agricultural development level in the Yangtze River Economic Belt. The results showed that the average annual yield increase rate of low-carbon agriculture development in the Yangtze River Economic Belt from 2012 to 2019 was 3.16%, leading the country by 0.57 percentage points. The agricultural economic indicators of the Yangtze River Economic Belt had increased by 0.222 3 points, with an average annual growth rate of 6.29%. The carbon level indicators of low-carbon agriculture in the Yangtze River Economic Belt had increased by 0.251 6 points, with an average annual growth rate of 6.41%. Electricity consumption, fertilizer use, and carbon sink had a positive impact on carbon emission efficiency, while employees and pesticide usage had a negative impact on carbon emission efficiency.

Key words: Yangtze River Economic Belt, low carbon, agricultural development level, entropy value method, evaluation
