Resident income inequality has widened drastically within a short timeframe in the process of transition. From a static point of view, there is a combination of three factors underpinning the widening of the resident income gap. Such factors include a) the variation in quantity of factors of production accumulated during the planned economy era; b) the difference between localities in respect of starting points at different historical stages along their varying paths of evolution; c) the illegal and abnormal income stemming from institutional loopholes and policy deficiencies. From a dynamic point of view, there are three root causes underlying resident income gap expansion. Firstly, the privileged group has been continuing to benefit from an increasingly large share of institutional transition returns by exerting influence over the path of evolution; secondly, the underprivileged group has lost their ability to capture income on a sustainable basis due to the lack of a mechanism to express their interests; thirdly, public policies are not designed or enforced well enough to regulate income inequality. Given the significant effects of excess income disparity on economic performance and social stability, it is thus imperative to hold the income gap in check in light of the societal reality of the transitional stage. 展开更多

Resident income inequality has widened drastically within a short timeframe during the process of transition. From a static point of view, there is a combination of three factors underpinning the widening of the resident income gap. Such factors include a) the variation in quantity of factors of production accumulated during the planned economic regime; b) the difference between localities in respect of starting points at different historical stages along their varying paths of evolution; c) the illegal and abnormal income stemming from institutional loopholes and policy deficiencies. From a dynamic point of view, there are three root causes underlying resident income gap expansion. Firstly, the privileged group has been continuing to benefit from an increasingly large share of institutional transition returns by exerting influence over the path of evolution; secondly, the underprivileged group has lost their ability to capture income on a sustainable basis due to the lack of a mechanism to express their interests; thirdly, public policies are not designed or enforced well enough to regulate income inequality.

在区别性主从复合词的造词活动中,主从复合词本身才是命名活动的目标,词根是参照,前加成分是为了使目标区别于参照而给目标添加的区别标识。前加成分可以分化词根,也可以异化词根。由异化方式或完全分化方式造成的几个词之间呈连续性,... 在区别性主从复合词的造词活动中,主从复合词本身才是命名活动的目标,词根是参照,前加成分是为了使目标区别于参照而给目标添加的区别标识。前加成分可以分化词根,也可以异化词根。由异化方式或完全分化方式造成的几个词之间呈连续性,其系统比较稳定;由不完全分化造成的词呈离散性,其系统不稳定。分化与异化之间可以互相转化,条件是泛化或特化及有无标记对立的建立和失效。 展开更多
