The Fifth Plenary Session of the 19th CPC Central Committee proposed that during the "14th five year plan" period, we should firmly establish and practice the concept that clear waters and green mountains are invaluable assets, take multiple measures to promote green development and promote the harmonious coexistence of human and nature. In the face of the gradual depletion of natural resources and environmental degradation, green sustainable development can not stop at saving resources and reducing emissions, but also need to increase investment in resources and environment.In order to increase the investment in resources and environment, we must introduce and clarify four very important concepts and their relationship with the investment in resources and environment.First, the marginal income of factors. In order to overcome and alleviate the trend of marginal decline, the only possibility is to invest in natural resources, promote technological progress, increase the supply of natural resources and improve their quality.Second, land and other natural resource capital. With the rapid development of social economy, the natural force of land needs not only compensation, but also investment in capital to establish an effective mechanism for people to use natural force rationally.Third, ecological wealth. Instead of sacrificing ecological wealth for the sake of material wealth, we should firmly establish the idea that "protecting the ecological environment means protecting the productive forces, and improving the ecological environment means developing the productive forces".Fourth, resource property rights. The key to avoiding the tragedy of natural resource commons is to have an exclusive property right system, change people's excessive use of public property, and improve resource utilization efficiency.
