【摘要】:收入分配問題是宏觀經(jīng)濟(jì)學(xué)中重要的研究?jī)?nèi)容,經(jīng)濟(jì)的發(fā)展過(guò)程中伴隨著收入的增長(zhǎng),而如何使得經(jīng)濟(jì)增長(zhǎng)的成果有效率且公平地分配到國(guó)民手中,是政府和社會(huì)都關(guān)注的問題。我國(guó)的經(jīng)濟(jì)伴隨著改革開放有了很大的發(fā)展,人均收入水平有了很大的提升,然而我們不能忽視的是仍然有一部分群體還沒有享受到經(jīng)濟(jì)發(fā)展應(yīng)得的成果。不可否認(rèn)的是,我國(guó)的減貧工作有了很大進(jìn)步,然而仍然有很大的空間有待提升。但是我們應(yīng)該正視的是,不同的收入階層的差距在逐步擴(kuò)大,要縮小收入差距,貧困群體最應(yīng)該得到關(guān)注。本文正是基于此對(duì)貧困群體的收入變化狀況進(jìn)行研究分析的。 本文基于CHNS數(shù)據(jù)庫(kù)提供的個(gè)人收入數(shù)據(jù),結(jié)合分位數(shù)回歸法,選取了教育、工作經(jīng)驗(yàn)、邊際工作經(jīng)驗(yàn)、性別和城鄉(xiāng)這五個(gè)影響因素構(gòu)建了我國(guó)居民收入分位數(shù)回歸模型,并對(duì)各統(tǒng)計(jì)年份的居民收入進(jìn)行研究。重點(diǎn)關(guān)注貧困群體的收入變化狀況,發(fā)現(xiàn)貧困群體的收入雖然有了數(shù)量的提升,但是還是遠(yuǎn)低于聯(lián)合國(guó)提出的每人每天1美元的貧困線標(biāo)準(zhǔn),我國(guó)貧困群體的生存狀況堪憂。進(jìn)一步運(yùn)用Machado和Mata的分位數(shù)分解法做各因素對(duì)收入的影響分解發(fā)現(xiàn),教育和工作經(jīng)驗(yàn)這兩個(gè)影響因素的特征效應(yīng)起作用較大,而邊際工作經(jīng)驗(yàn),性別和城鄉(xiāng)這幾個(gè)因素的系數(shù)效應(yīng)起主要作用。并且本文依據(jù)這些研究所得結(jié)果,提出一些相應(yīng)的提高貧困群體收入,縮小分配不均的政策建議。
[Abstract]:The problem of income distribution is an important research content in macroeconomics. In the process of economic development, it is accompanied by the growth of income, and how to make the fruits of economic growth distribute efficiently and equitably to the hands of the people. It is a problem that the government and society are concerned about. Along with the reform and opening up, China's economy has made great progress, and the level of per capita income has been greatly improved. However, we cannot ignore that there are still some groups that have yet to enjoy the fruits of economic development. Undeniably, the country has made great progress in reducing poverty. However, there is still a lot of room for improvement. However, we should face up to the fact that the gap between different income groups is gradually widening and the income gap should be narrowed. The poor groups should be paid more attention. This paper studies and analyzes the income changes of the poor groups. Based on the personal income data provided by CHNS database and the quantile regression method, this paper constructs the income quantile regression model of Chinese residents by selecting five influencing factors: education, work experience, marginal work experience, sex and urban and rural areas. And study the income of residents in each statistical year. Focus on the income changes of the poor groups, and find that the income of the poor groups has increased in quantity. However, it is still far below the poverty line standard of US $1 per person per day proposed by the United Nations, and the living conditions of the poor groups in our country are worrying. Further, we use the quantile decomposition method of Machado and Mata to analyze the effects of various factors on income. The characteristic effects of the two influencing factors, education and work experience, play an important role, while the coefficient effects of marginal work experience, gender and urban and rural factors play a major role. Put forward some corresponding policy recommendations to increase the income of the poor groups and reduce the uneven distribution.
