In 2000～2012，countrywide total investment into public culture increased from 30.029 billion yuan to 226.835 billion yuan，with a remarkably average annual growth of 18.35%. The cultural investment growth is evidently higher than GDP growth，but certainly lower than the fiscal revenue growth，and also slightly lower than the fiscal expenditure growth；At the same time，evidently lower than education investment growth，and also significantly lower science & technology investment growth，as well as remarkably lower health investment growth. The ratio of culture investment to fiscal revenues is evidently lower than that of the cultural consumption to the residents’ income. Public cultural investment growth lags behind the demand changes of the residents’ cultural consumption. To measuring the “growth space” of countrywide culture investment in 2012：if it should get the ought-to-be growth at the best ratio over the years in terms of the productive value，the fiscal expenditure，the E.S.C.H. investment and the culture investment，it would reach 405.713 billion yuan；if the balanced isomorphism proportion of culture investment and consumption should come true，it would reach 627.699 billion yuan；if the ideal growth of the equal culture investment should realize，it would reach 934.231 billion yuan. <<
