the overall trend of China’s economic development is good. At the beginning of 2020，affected by the new crown epidemic，China’s economy declined，posing new challenges to China’s economic development. Starting from the income of residents，this paper analyzes the structural weakness of China’s economy，and finds that both the developed countries and several countries trapped in the middle-income trap have experienced 10-20 years of double-digit growth in their development history，but the final results are quite different. By analyzing the relationship between factors of production and GDP in the period of rapid development，we can see that economic growth mainly comes from the sustained growth of population，steady consumption，strong output of science and technology，and service industry. At present，the growth rate of per capita disposable income is weak，which restricts the economic development. Compared with the process of economic development at home and abroad，the paper points out that there are efficiency depressions in economic development. Replenishing the low-lying areas of efficiency will boost the economy to a higher speed.
