The ‘External revenue’ is one of the most important factors which affect the income and the synchronization of economic growth. This article compares the National Bureau of statistics of household survey data with the “cash flow” data. Based on this fact，itestimates the scale and structure of the recent ‘external revenue’ and also analyses the factors which impact the synchronization between residents’ income and economic growth. Based on the recent research，the income of urban and rural residents on the basis of household survey data is known as ‘external revenue’. According to the “funds flow statement”，the missing rate of the disposable income per capital fluctuates between 18 to 27 percent. Since 2012，the omission rate has started to decrease gradually and in 2014 the rate has been 20.6 percent. The economic situation leads to a low rate of wage and transfer income and a high rate of operating and property income，and also brings a negative impact on omission rate due to the reform of statistical system. The existence of the large number of ‘external revenue’ means that the actual residential income level is higher than the expected level and the synchronization between income and economic growth will be positive. On the other hand，this also means that it will be more difficult to double the residential income per capita in 2020 compared with that in 2010. Overall，the growth of income and economic growth will be maintained.
