Abstract: This study selects 19 key indicators influencing the urbanization quality from six aspects, including economic and social development quality, efficiency of urbanization,environmental development quality,urban-rural gapandresidents living conditions. An evaluation index criterion of urbanization quality in the Economic Zone on the West Coast of the Taiwan Straits (EZWCTS) of China is built based on above 19 key indicators by using factor analysis method.The spatial and temporal evolution characteristics and driving factors of urbanization quality are analyzed. The results show that the urbanization quality in the EZWCTS presents an overallincreasing trend from 2005 to 2014. The growth of urbanization quality for most of the cities are at the positively accelerating trends in the EZWCTS , while the development gap among different cities is gradually enlarged.The spatial interaction amongthe cities is relatively largefrom 2009 to 2014,presenting a dramatic spatial spillover effect and spatial heterogeneity. The polarization center mainly focuseson the east coast. Economic and social development quality, environmental development quality and efficiency of urbanization are the main driving factors.Economic and social development quality and efficiency of urbanization of majority of the cities show a similar development trend, but Economic and social development quality and environmental development quality of themshow an opposite one. The elasticity to each driving factor is relatively smaller for the developed cities, while the sensitivity to each driving factor is relatively higher for the small-medium cities.
