Abstract：Based on summarizing the study situation of city scale at home and abroad, we draw three conclusions:First, city scale has a proper range and change with different time and place; Second, there is a close relationship between cities' birth and the development of regional economy, whether the scale is rational or not can be reflected from the viewpoint of regions. Generally speaking, a region will not have the best synthetical efficiency until it has a proper distribution of city scale. Third, the proper scale of city should be considered based on its economy, society and environment, but economy and society efficiency is the key point. Then thirteen cities' scale efficiency in Shannxi province is studied from the aspects of economy, society and environment through means of Grey Relevance Total Analysis. According to the results, these cities are divided into three types:strong, middle and weakness. The characteristics of city scale and grade structure of thirteen cities in Shaanxi Province are as follows:Special big city is developing lonely; Big cities with a population of half to one million are scarce; the speed of evolution from middle size into big city is slow; small cities are set up slowly. According to this characteristics, the best strategy of urban scale efficiency are put forward:First of all, special big city, Xi'an should be developed firstly and by the aid of its high efficiency, the other cities will be promoted to develop quickly. Secondly, we should take an active part in developing some middle and small cities. Middle cities such as Xianyang and Baqji should be developed into big cities quickly, small cities such as Yan'an、Yulin and Ankang should be developed into middle grade cities, important counties such as Qishan、Pucheng、Fuping、Qixian、Mianxian、Chenggu、Luoyang、Shengmu、Huan glin、Huxian etc should reach the city standard or achieve the aim of changing into cities.
