What does "urbanization of social security" mean?

After the new policy of "social security in the same city", you can buy a house in Tianjin after two years of social security in Beijing, which is a misunderstanding of the establishment.

Tianjin Public Security Bureau recently denied the story. In addition, the policy was jointly issued by Tianjin Public Security Bureau, Tianjin Human Resources and Social Security Bureau and Tianjin Education Commission. The policy terms are also clearly written: formulate the policy of the integration of employees of Beijing-Hebei enterprises to pay social insurance, that is, allow employees of Beijing-Hebei enterprises that have paid social insurance in Beijing and Hebei to declare to settle in Tianjin.

In other words, the policy of recognizing social insurance in the same city is only aimed at the employees of Beijing-Hebei enterprises introduced by the established system. Beijing has social security, but Tianjin has a house.
