With regard to heavy industry, the leadership's position was muddled. In his "Fourth Political Report" Lê Duẩn stated that during the transition to socialism, priority would be given to heavy industry "on the basis of developing agriculture and light industry". In another section of the report, Lê Duẩn stated that light industry would be prioritised ahead of heavy industry. The position of Phạm Văn Đồng, the Chairman of the Council of Ministers (the head of government), was just as confused as Lê Duẩn's. In practice Lê Duẩn prioritised heavy industry: 21.4% of state investment was in heavy industry in the Second Five-Year Plan and 29.7 percent in the Third Five-Year Plan (1981–85). Light industry only received 10.5 and 11.5, respectively. From 1976 to 1978 industry grew, but from 1979 to 1980 industrial production fell substantially. During the Second Five-Year Plan industry grew just 0.1 percent. The 6th Plenum of the Central Committee criticised the policy that the state had to own everything.
