宋代是我国封建社会由前期到后期的转折时期,流动性比较强的地主土地所有制的兴起和非身份性官僚地主统治地位的确立,为商品经济的空前发展,尤其是商业资本势力的膨胀提供了便利条件。在商品交换原则的支配下,土地已作为商品越来越深地卷入流通领域,人们“有钱则买,无钱则卖”,土地所有权转易频率大大加快,因而出现了“贫富无定势”、“富儿更替做”的新经济格局。与此同时,昔日地主阶级内部“士庶天隔”和“以贵承贵,以贱袭贱”的旧政治格局已被“朝廷无世臣”和“贱不必不贵”新政治格局所取代。这种经济政治地位的动荡,反映了以往板结化的社会结构,特别是富与贫、贵与贱的凝固性已渐被打破,而社会的流动性、竞争性日益增强。 The Song Dynasty was the turning point of the feudal society in our country from the previous period to the later period. The rise of the landlord land ownership with relatively liquidity and the establishment of the non-identity bureaucrat landlord’s dominant position provided the unprecedented development of the commodity economy, especially the expansion of the commercial capitalist forces Convenient conditions. At the domination of the principle of commodity exchange, land has become increasingly involved as a commodity in the circulation field. People “buy while they have money, they sell without money”, and the frequency of the transfer of land ownership is greatly accelerated, resulting in the emergence of “rich and poor Set the trend ”,“ rich children do ”new economic pattern. In the meantime, the old political structure of “commoners and brutals” and “bearing your own costs and depravity” in the former landlord class has been replaced by the new political pattern of “no imperial court” and “cheapness not expensiveness” . The turmoil in this economic and political status reflects the social structure that has been consolidated in the past. In particular, the solidarity of wealth and poverty, expensiveness and cheapness has gradually been shattered, and the social mobility and competitiveness have been increasingly enhanced.
