【摘要】：收入差距是影響宏觀指標(biāo)的一個(gè)重要因素,但其影響機(jī)制及計(jì)量分析方法有待進(jìn)一步深化拓展。通過構(gòu)建一個(gè)包含基尼系數(shù)的宏觀總量函數(shù),嚴(yán)格論證了收入差距影響宏觀指標(biāo)的理論機(jī)制�；诤暧^總量函數(shù),推導(dǎo)出收入差距的宏觀總量損失公式和收入差距變化對(duì)宏觀總量指標(biāo)變化影響的差分公式。利用1996~2010年中國(guó)的宏觀數(shù)據(jù)計(jì)算表明:收入差距導(dǎo)致居民總消費(fèi)平均損失率為2.68%,導(dǎo)致國(guó)民福利平均損失率為8.66%,收入差距擴(kuò)大對(duì)居民消費(fèi)率下降的貢獻(xiàn)率為3.18%,對(duì)勞動(dòng)收入份額下降的貢獻(xiàn)率為14.98%,對(duì)國(guó)民福利增長(zhǎng)的貢獻(xiàn)率為-8.08%。
[Abstract]:Income gap is an important factor affecting macro-index, but its influence mechanism and metrological analysis method need to be further expanded. By constructing a macro-aggregate function including Gini coefficient, this paper strictly demonstrates the theoretical mechanism of income gap affecting macro-index. Based on the macro aggregate function, the macro total loss formula of the income gap and the difference formula of the influence of the income gap change on the macro aggregate index change are derived. Based on the macro data of China from 1996 to 2010, the results show that the average loss rate of total consumption is 2.68% and the average loss rate of national welfare is 8.66% due to income gap. The widening income gap contributed 3.18 percent to the decline in the consumption rate of residents, 14.98 percent to the decline in the share of labor income, and-8.08 percent to the growth of national welfare.
