I would say that current lunar missions are largely driven by national desires for prestige, at least primarily for the non-American nations, e.g. China, India, and Israel. The two Chinese lunar rover missions were explicitly designed as part of an overall architecture with an eye to conducting unmanned sample return missions followed by manned lunar exploration.

However, there's still plenty of science to be done on the lunar surface, not the least of which would involve prospecting for in-situ resource utilization.

Ultimately, though, I think there are additional plans above and beyond what was accomplished with Apollo, not the least of which would be to set up permanent manned facilities to conduct additional research and experimentation. Being able to conduct off-world testing on the moon is seen as a stepping stone to eventual plans for exploring Mars.
Finally, there also seem to be a number of private corporations looking to hitch rides to the moon in order to explore possible business use cases.
