can GDP full evaluate the development progress of one nation
is there any other indicators to evaluate or define the development
参考答案:Measures of national income and output are used in economics to estimate the value of goods and services produced in an economy. They use a system of national accounts or national accounting first developed during the 1940s. Some of the more common measures are Gross National Product (GNP), Gross Domestic Product (GDP), Gross National Income (GNI), Net National Product (NNP), and Net National Income (NNI). Formerly in the Soviet Union and its satellite states COMECON, Net Material Product (NMI) was estimated (NNP-Services). In relation to greening the national accounts the United States Congressional Budget Office concludes "a gradual process of modifying measures of national economic performance is consistent with the history and development of the national accounts."
There are at least two or three different ways of calculating these numbers. The expenditure approach determines aggregate demand, or Gross National Expenditure, by summing consumption, investment, government expenditure and net exports. On the other hand, the income approach and the closely related output approach can be seen as the summation of consumption, savings and taxation. The three methods must yield the same results because the total expenditures on goods and services (GNE) must by definition be equal to the value of the goods and services produced (GNP) which must be equal to the total income paid to the factors that produced these goods and services (GNI).
In actual fact, there will be minor differences in the results obtained from the various methods due to changes in inventory levels. This is because goods in inventory have been produced (and therefore included in GDP), but not yet sold (and therefore not yet included in GNE). Similar timing issues can also cause a slight discrepancy between the value of goods produced (GDP) and the payments to the factors that produced the goods, particularly if inputs are purchased on credit.
