How to calculate the contribution rate of welfare

Contribution rate is often used in statistical work, so what is the meaning of contribution rate? How is it calculated? Contribution rate is an index to analyze economic benefits. It refers to the ratio of effective or useful results to resource consumption and occupation, that is, the ratio of output to input, or the ratio of income to cost. Calculation formula: contribution rate (%) = contribution (output, income)/input (consumption, occupation)? The contribution rate of 100% is also used to analyze the role of various factors in economic growth. The calculation method is: contribution rate (%) = contribution (increment or degree of growth) of a certain factor/total contribution (total increment or degree of growth)? 100% actually refers to the ratio of the growth (degree) of a certain factor to the total growth (degree). Examples are as follows: total assets contribution rate (%) = (total profit+total tax+interest expense)/average total assets? 100%( 1) total asset contribution rate: it reflects the economic benefit of the enterprise's capital occupation and shows the profitability of the enterprise in using all assets. (2) Social contribution rate: measure the ability of enterprises to use all their assets to create or pay value for society. Social contribution rate (%) = total social contribution/average total assets? 100% of the total social contribution includes social welfare expenditure such as wages, labor insurance and retirement planning, net interest expenditure, value-added tax payable, product sales tax and surcharges, income tax payable and other taxes, net profit, etc. In order to reflect the contribution of enterprises to the country, the contribution rate can be calculated according to the above principles. Contribution rate of enterprises to the country (%) = total tax revenue+paid profits/total social contribution? 100% Contribution rate of technological progress to output growth rate This indicator refers to the proportion of technological progress factors in output growth rate, which comprehensively reflects the role of technological progress in economic growth. Contribution rate of technological progress to output growth rate (%) = technological progress rate/output growth rate? The greater the contribution rate of 100%, the greater the contribution and role of technological progress to economic growth, and vice versa. (4) Contribution rate of each industry: the ratio of the increment of primary, secondary and tertiary industries to the increment of GDP is the contribution rate of each industry. Contribution rate of tertiary industry = tertiary industry increment/GDP increment in the current year? 100% It should be noted that the contribution rate indicator is abstract. When using, the specific meaning should be stated, but it should not be used at will. To conform to the routine, it is necessary to standardize, standardize and popularize. For example, the rate of return on capital, the rate of profit and tax on capital and some indicators used for incremental factor analysis all have special names, so it is unnecessary to rename them contribution rates. In addition, when calculating the contribution rate of each industry, the price change factor should be eliminated, and the numerator and denominator should be calculated according to the comparable price increment.
