英文摘要：

The investor protection is an important factor to affect the development of capital market. Can it explain China＇s regional difference of capital market development？ Based on China＇s provincial data, this paper explores how the different investor protection influences China＇s regional difference of capital market development （RDCMD） under the same legislative environment. This difference of investor protection is caused by legal enforcement and interprovincial residual corporate governance （IRCG） represented by local laws and regulations. We draw the following conclusions： （ 1 ） the investor protection is one of the important reasons for forming China＇s RDCMD and （2） the judiciary is the main reason for producing the difference of the investor protection in China＇s various regions and has the significant influence on the RDCMD and （3） the influence of IRCG on the RDCMD is uncertain.
