The plan also stressed the development of small-scale industry to meet Vietnam's material needs, create goods for export, and lay the foundation for the development of heavy industry. In the South, this entailed transforming some private enterprises into "state-private joint enterprises" and reorganizing some small-scale industries into cooperatives. In other cases, however, individual ownership was maintained. Investment in light industry actually decreased by 48 percent while investment in heavy industry increased by 17 percent during the first two years of the plan. Nonetheless, the increase in light-industry production outpaced that of heavy industry by 33 percent to 28 percent during the same two-year period.
