In this study, we examine sustainability conditions of the renewable resource under two sector optimal growth model without social planner and co-operation by its owners or users. We assume that, moreover, each representative agent doesn't take account of the renewal of renewable resource. And in this part of our study, we examine the cases of the constant returns to scale production technology in each sector and that with the exogenous technological progress in sector2 (manufacturing sector).The findings of this part are as follow. First, renewable resource can be sustainable under exogenous technological progress, but this must be met following conditions. (1) Potential capacity in the renewable resource is large enough compared with economic activities. (2) Steady state level of physical capital per capita is constant over time and smaller than the critical level of physical capital determined by the potential capacity in the renewable resource. And (3) there must be the initial level of renewable resource which can generate the growth of renewable resource at initial time. Second, however, no longer renewable resource can sustain at positive level with exogenous technological progress.
