text: Data from Chinese National Statistical Bureau show that at the end of the Mao era, China's industrialization largely focused on three regions. Manchuria, the former Japanese colony, inherited a considerable industrial base from the Republic era and continued benefitting from its rich natural resources. The second one was the broad area centering Shanghai, including the Zhejiang-Jiangsu region, which was also historically advantaged. The third concentration included Inner Mongolia, Xinjiang, and western Sichuan, which was largely historically marginalized but gained fast development through the party's Third Front policy.
  Family and gender
  Family structure during the Mao era also changed. The marriage law in 1950 granted more agency to women for marriage and divorce and advocated equal relations between husbands and wives. It prohibited concubinage and child brides. Following the path of the Nationalist government, the state also promoted an equal relationship between parents and children. The marriage law reinforced the mutual legal bonds for both parents and children. Not only did it stipulate the children's obligation to provide old-age support to their parents but it also emphasized parents' legal duty of raising and supporting their children. Meanwhile, the new social systems that re-arranged people into work units or communes altered the parent-child relations and weakened the historically significant parental authority. Remunerated by work points, family members became less financially dependent on each other.
