The invention relates to a big data-based customer relationship management and service intelligent tracking system and method. The system comprises a big data-based analysis server, a relay server based on a cloud computing platform, a communication protocol management server, a network identity authentication server, and a database server. The big data-based analysis server, the communication protocol management server, the network identity authentication server and the database server are all in data connection with the relay server based on a cloud computing platform. The tracking method comprises the four steps of system assembly, system prefabrication, service monitoring and customer analysis. According to the invention, the requirements of remote acquisition and centralized analysis operation of various service working contents, working environments and various complex data can be effectively met; and meanwhile, expected service requirements of customers can be accurately analyzed and pre-judged, so that the aim of improving the service work development efficiency, precision and quality is fulfilled, and the service work development cost is reduced.
