It is a trade-off between social equity and efficiency to choose between large-sized units and small-sized units. The contradiction between the two, to some degree, is a measurement of the difference between maximization an enterprise’s interests and the maximization of social welfare. To the developers, it is an optimal allocation of resources to build large-sized units, particularly at the superior location, targeting high-income clientele. However, the same land could serve more households if small-sized units were built on it. There is no doubt that to build more large-sized units means that there will be less land resources of similar condition to serve the the mid-to-low income group,who can only afford small-sized units. This group of people can only hope nothing.

英语就基本上是这样了。但是想提醒楼主一下，并不是只有户型大小能决定企业利益或者社会利益。更重要的是开发密度，或者说容积率。

Large and small-sized unit that contains the relationship between social equity and efficiency of trade-off. The contradiction between the two has to a certain extent a measure to maximize the interests of enterprises and social welfare to maximize the distance. To the developers for high-income groups of large units more lucrative profits, especially in the more advantageous geographical location of the lot and build large units are more like the optimal allocation of resources. There is no doubt that the large size means that the building of the same land area to meet the needs of the less settled down, targeting a large number of small units in the low-income people can only hope that they can not afford housing.
