Whether accommodation can be provided has a lot to do with the geographical location, consumption level and convenience of life of the unit. Most of the units that provide accommodation are suburban production enterprises, which employ a large number of labor. The cost of building dormitory, canteen and other facilities in the suburbs is low, so you don't have to work outside after work, and you can't recruit people without building them. Most small and medium-sized enterprises working in the city center do not have this condition. The rent in downtown is expensive, so it is impossible for small and medium-sized enterprises to invest money to rent dormitories and build canteens for employees. Having dormitories and good welfare is also the reason why many talents choose state-owned enterprises. But the objective situation is that many job seekers pay more attention to the accommodation provided by enterprises, because they can't arrange the accommodation environment at a lower cost, and those who struggle for it have a lot of troubles. Therefore, enterprises in IT, securities, finance and other fields with fierce competition for talents tend to arrange dormitories for their employees.
