Capacity Reduction Policy On The Quantity Andquality Of Economic Growth Nonlinear Effect Research

Overcapacity is a by-product of rapid economic growth for many years,not only occupy a large number of physical resources in industries with excess capacity and credit resources,overall economic resource allocation efficiency is low,but also,the low end of the backward production capacity of total growing brought serious environmental pollution,economic giant "quantity" not only failed to achieve the"qualitative" makes economic growth into "low-quality trap",Therefore,the problem of overcapacity is an urgent problem to be solved in the process of promoting China's high-quality economic development.The academic discussion on the problem of overcapacity has been continuing up to now.Different scholars analyze the problem of overcapacity from different perspectives,explore the causes of overcapacity,analyze the impact of overcapacity,and then hope to provide some feasible paths for the governance of overcapacity,to achieve the goal of reducing overcapacity.But excess capacity management has been in a state of no avail,increasingly serious overcapacity serious negative impact on economic growth,and the quality of its performance is economic growth important chronic overcapacity problem,serious overcapacity problem and run counter to the requirements of high quality and economic development in our country,the contradiction of the two has come to the point where incompatible to solve.But do capacity are not just simple economic "subtraction" process,but also pay attention to the capacity to process for high quality production,back into the "better" to capacity is the effective way to optimize the supply system of the quality of,it involves to capacity by means of specific whether can backward in removing inefficient capacity at the same time to form high quality production Therefore,what kind of means can be adopted to eliminate overcapacity and most effectively reconcile the contradiction between "quantity" and "quality" of economic growth has become the key to this problem.Based on the existing studies on the effect of environmental regulation and technological innovation on the capacity reduction,it can be confirmed that environmental regulation and technological innovation are two effective ways of the capacity reduction.However,what effect will the capacity reduction have on the economic growth through different ways.At present,when the problem of overcapacity and the problem of improving the quality and efficiency of economic growth are both prominent,it has become an important problem to be solved to explore which way to reduce capacity can produce the best effect on economic growth.Therefore,it is necessary to further study the difference of the effect of reducing capacity on economic growth under the effect of different ways to reduce capacity.In the above research background,based on the provincial panel data of China from 2003 to 2016,this paper investigates the linear effect of capacity reduction on the economic growth in quantity and quality,discusses under the different environmental regulation and different level capacity of technological innovation nonlinear effect of economic growth in quantity and quality,and tentatively inspection to capacity on economic growth,with the consideration of environmental constraints nonlinear effect of quantity and quality of economic growth.The results show that:first,theoretical analysis and linear model show that the capacity reduction will have a significant negative effect on the quantity of economic growth and restrict the growth of economy in the quantity dimension,while the capacity reduction has a significant positive effect on the quality of economic growth and can promote the improvement of the quality of economic growth;Second,there is a non-linear effect on the quantity and quality of economic growth under different environmental regulation intensity.The negative effect of lower environmental regulation intensity on economic growth quantity is significant.With the increase of environmental regulation intensity,the policy of reducing capacity will weaken its negative effect on economic growth quantity.Under moderate environmental regulation intensity,capacity reduction can produce the maximum improvement effect on the quality of economic growth,while both too high and too low environmental regulation intensity cannot make capacity reduction achieve the best improvement effect on the quality of economic growth.Third,There are nonlinear effects on the quantity and quality of economic growth under different technological innovation levels.The effect of capacity reduction on economic growth quantity will gradually turn from negative to positive under the background of improving technological innovation level.At a moderate level of technological innovation,the capacity reduction can greatly promote the quality of economic growth.Too high or too low level of technological innovation will damage the capacity reduction's effect on improving the quality of economic growth.
