Resources, Enviromental Pollution And Macroeconomic Growth

In this paper,we discuss three types of economic growth models which analyse the influences of exhaustible resources,the enviromental pollution and the reserve ratio on economic development respectively.In the model which includes the exhaustible resources,we consider two different conditions.First,we exclude the progress of technology.Using the method of dynamic optimization,we derive a steady system.But the following result contravene the want of sustainable economic development.Thus,we can see,without the progress of technology,the society can never get sustainable economic development.To overcome the disadvantage,we rebuild the model.This time we introduce the resourcers into the R&D endogenous economic model.In this model,we get a simple endogenous growth model with two departments.One is the production department,the other one is the R&D department.Analysing like the former model,we obtain the balanced growth rate and deduce some suggestion for choosing economic policies.In the second part of the paper,we establish a simple model of enviromental pollution which generates the relation between per capita income and enviromental quality.At last,we analyse the relationship between the reserve ratio and the economic development.We draw the conclusion that it takes less time for the economy constringing to the steady state when the reserve ratio get larger.
