三、市场经济与共同富裕的矛盾性市场经济的收入分配机制主要是市场机制。从生产经营收入的取得,到原始收入的形成,再到国民收入的再分配,都要受市场机制的调节,受价值规律、供求规律和竞争规律的制约。在市场上,商品供求起伏波动,价格频繁涨落,存在多种差价(如地区差价、季节差价、质量差价、购销差价、批零差价等),行情变幻莫测,竞争异常激烈,这些复杂多变的情况都在影响着国民收入的分配和再分配,决定和调节着个人收入的高低,会产生巨额风险收入、机会收入,可能引起收入的高低悬殊。在市场经济条件下,资产所有者必须得到资产收益,即便资产所有者不是劳动者,同样也会得到各种非劳动收入,因此,市场经济本身不能消灭剥削,消除两极分化。对于社会上已经存在的贫富差别,市场经济本身不仅不能消除,相反还有可能扩大。因为拥有资产越多的人,经济实力越强、越有条件采用先进技术和新型设备,扩大生产规模,开发新产品,提高竞争能力;越有条件接受教育,提高科学技 Third, the contradiction between market economy and common prosperity The income distribution mechanism of market economy is mainly the market mechanism. From the acquisition of production and operation income to the formation of the original income and the redistribution of national income, all must be regulated by the market mechanism and subject to the laws of value, supply and demand and competition. In the market, the ups and downs of commodity supply and demand fluctuations, frequent price fluctuations, there are many kinds of spreads (such as regional differences, seasonal differences, the quality of the spread, buying and selling spreads, wholesale and retail spreads, etc.) unpredictable market, extremely competitive, these complex The situation is affecting the distribution and redistribution of national income, determine and adjust the level of personal income, will have a huge amount of risk income, opportunity income, the level of income may cause disparity. Under the conditions of a market economy, the asset owner must obtain the return on assets. Even if the owner of the asset is not a laborer, he or she will also receive various non-labor incomes. Therefore, the market economy itself can not eliminate exploitation and eliminate polarization. For the already existing differences between the rich and the poor in society, the market economy itself can not be eliminated, on the contrary, it is possible to expand. Because more people have assets, the stronger the economic strength, the more the conditions for the use of advanced technology and new equipment, expand production scale, develop new products, improve competitiveness; the more conditions for education, improve science and technology
