摘要
基于促进效应与抑制效应视角,构建农机购置补贴对农机作业服务市场规模影响的理论框架,运用随机变系数模型测算粮食主产区2004—2017年农机购置补贴对农机作业服务市场规模的影响方向与程度,并通过引入时间与农机购置补贴的交互项,进一步讨论农机购置补贴对农机作业服务市场规模的影响效率随时间的变化。研究发现:农机购置补贴对农机作业服务市场规模的影响在整体上是正向的,2004—2017年间对农机作业服务收入增量的贡献率为36.28%;但年度边际影响是逐渐下降的,农机购置补贴存量每增加100元/hm^2,农机作业服务收入增量从2004年的149.57元/hm^2减少到2017年的13.42元/hm^2;在内蒙古、辽宁、吉林、黑龙江四省中,农机购置补贴对农机作业服务市场规模呈现负向影响。
This paper constructs the theoretical framework of the impact of agricultural machinery purchase subsidy on the market scale of agricultural machinery operational service, based on the perspective of promoting effect and restraining effect. Calculate the influence direction and degree of the subsidy on the market scale of agricultural machinery operational service in the main grain producing areas from 2004 to 2017 using stochastic coefficient model. By introducing the interaction term of time and the subsidy, this paper further discusses the change in efficiency of the subsidy’s impact on the market scale of agricultural machinery operational service with the increase of years. The results show that the effect of agricultural machinery purchase subsidy on the market scale of agricultural machinery operation service is positive on the whole, and the contribution rate of it to the increment of agricultural machinery operation service income is 36.28% from 2004 to 2017. But the annual marginal effect is gradually decreasing, for every 100 yuan per hectare increase in the stock of agricultural machinery purchase subsidy, the incremental income of agricultural machinery operation services decrease from 149.57 yuan per hectare in 2004 to 13.42 yuan per hectare in 2017. Agricultural machinery purchase subsidy has a negative impact on the scale of agricultural machinery operation service market in Inner Mongolia, Liaoning, Jilin and Heilongjiang.
