摘　　要：在传统新古典经济增长模型框架下,将“经济增长率偏好”显式地引入到效用函数,从理论上分析这种因喜欢高增长率的偏好对经济所产生的潜在影响.研究发现,许多结果与直观想象是有差异的.它对稳态消费的影响并不像预期那样是单调递增的,适度的经济增长率偏好才可以使得稳态消费超过传统模型中的稳态消费;如果初始资本存量已经比较高,那么经济增长率偏好的上升反而会使得总效用降低;经济收敛速度在稳态附近随经济增长率偏好的上升将变得更缓慢;时间偏好等参数对稳态资本存量的影响也不再具有单调性.研究结果说明,政府过度地追求高经济增长率或不顾发展阶段一味地偏好经济增长率,都可能会带来产能过剩、总效用降低等负面影响;通过诸如“晋升锦标赛”等反映经济增长率偏好的激励方式来促进经济增长,其作用可能十分有限.In the framework of the traditional neoclassical economic growth model,the“economic growth rate preference”,or LGR for short,is introduced into the utility function,and its potential impact on economic growth is analyzed.It is shown that many properties of the new model are not the same as expected.Specifically,the steady consumption is not monotonically increasing in LGR-only through a moderate degree of LGR,can the new steady consumption exceed the one for the traditional model.If the initial capital stock is already at a high level,a further increase in LGR will decrease the lifetime utility.A higher LGR tends to reduce the rate of convergence near the steady state.Unlike in the traditional model,factors such as time preference no longer have monotonic effect on the level of steady capital stock in our new model.These results also indicate that,some negative effects,such as overcapacity or utility loss,may occur if the government favors LGR too much or blindly loves the rate of economic growth regardless of developing stages.In addition,effects of boosting growth through incentives associated with growth preferences,such as promotion tournament,can be very limited.
