From 2000 to 2018，in the countrywide composition of gross domestic product，the secondary industry decreased from 45.54% to 40.65%，and the tertiary industry increased from 39.79% to 52.16%；in that of income approach components of gross domestic product，the compensation of employees （resident sector） decreased from 51.38% to 47.30%，the net taxes on production （government sector） decreased from 15.40% to 14.24%，and the operating surplus （enterprise sector） increased from 19.06% to 25.04%；in that of gross domestic product by expenditure approach，the final consumption rate decreased from 63.30% to 54.31%，and the capital formation rate increased from 34.33% to 44.85%；in that of income and expenditure by primary distribution，the revenue rate of public finance increased from 13.36% to 20.37%，the household income rate decreased from 46.37% to 45.11%，and the household consumption rate decreased from 35.91% to 31.53%. The regional gaps of the gross domestic product，total revenue of government finance，total expenditure of government finance，household income and total consumption in per capita value were all reduced；and the urban-rural per capita ratio of the household income and total consumption were all also reduced；thus “the unbalanced and inadequate development” improved a lot. The evaluation of the countrywide structure optimization of the economic growth：the lateral evaluation of the ideal ideal value without urban-rural and regional gap was 91.78；the vertical evaluation of self-base value was 243.32，169.04，121.74，105.88 and 102.18 respectively in 2000，2005，2010，2015 and 2017. Compared with the ideal lateral value，there was still a gap，and from the longitudinal view of the every five-year period，the progresses were made obviously.
