Abstract: Internet and big data are deeply changing the mode of regional public service,and China's regional public service is gradually changing from "new regionalism" to "regional shared public service".The regional integrated public service is no longer solely dependent on the combination of administrative divisions or the expansion of metropolitan governments.Instead,the regional public service sharing is being driven by information technology,which is seen in the following aspects:the values of regional public services are changing to shared values;information and big data are dispelling the administrative barrier of regional service;regional public service resources are changing from disequilibrium allocation of administrative space to integration,equalization and sharing of information space;and the organizational structure of regional public service is changing from bureaucratic system to talent sharing mechanism and project innovation system.

Key words: regional public service, internet medical treatment, shared public service, talent sharing
