Abstract
With China's economy entering the stage of high-quality development, manufacturing energy carbon emission efficiency has become the focus of academic attention. It is of great significance to study the convergence of manufacturing energy carbon emission efficiency for realizing high-quality development of manufacturing in China. Based on the panel data of China's manufacturing sub-sectors, this paper measures and analyzes the evolution trend of manufacturing energy carbon emission and its efficiency. On this basis, this paper uses the coefficient of variation and convergence model to test the convergence of manufacturing energy carbon emission efficiency. The results show that China's manufacturing energy carbon emissions and its efficiency demonstrate an increasing trend. Coal was the main source of manufacturing energy carbon emissions. The manufacturing energy carbon emission efficiency does not have σ convergence, but has [Formula: see text] convergence, and its convergence has industry heterogeneity. The manufacturing energy carbon emission efficiency exits scale effect and technology effect, but not the effect of opening to the outside world and institutional effect, and its effect exists industry heterogeneity. By reducing carbon emissions, adopting differentiated policies, adjusting the industry scale, and enhancing the industry technology intensity, China's manufacturing can improve the energy carbon emission efficiency and promote high-quality economic development.

Summary
Since the reform and opening up, China has made great achievements in economy. China's gross domestic product was only RMB 367.87 billion in 1978, RMB 10028.81 billion in 2000 and RMB99086.51 billion in 20191. Since the reform and opening up, China has made great achievements in economy. China's gross domestic product was only RMB 367.87 billion in 1978, RMB 10028.81 billion in 2000 and RMB. It is faced with the problems of low resource utilization efficiency, increasing of energy consumption and carbon dioxide emissions. According to data of British Petroleum report, China's carbon dioxide was 7710.1 million tonnes in 2009 and 9825.8 million tonnes in 2019,The average annual growth rate is 2.6% from 2008 to 2018 and 3.4% in. China faces great pressure on carbon emission reduction. China's per capita carbon emission is lower, its total carbon emission ranks first in the world.
