The present invention provides a multifunctional electronic commerce system which is an integrated electronic commerce system platform researched and developed for demands of a scientific research laboratory. The multifunctional electronic commerce system is partitioned into two parts. An online part provides a laboratory information management system scheme, wherein the system comprises: a laboratory purchasing platform, a laboratory material management system, a laboratory personnel management system, and a laboratory project management system; and by depending on advanced Internet application technologies, the system not only provides an electronic commerce purchasing platform for science researchers, but also provides a management platform, which has powerful functions, is stable to run and is convenient and rapid to operate, for a laboratory manager. The other part is an offline member club. Members accumulate points through an online platform and the points can be exchanged for offline activities, such as a professional lecture, an outdoor activity and the like, thereby comprehensively building up a social circle for biological science researchers.
