The Effect Of Structural Adjustment On The Growth Of Agricultural Total Factor Productivity

Supply-side structural reform is to promote structural adjustment and promote total factor productivity(TFP)growth.One of the important signs of agricultural modernization is the continuous growth of agricultural TFP.Under the joint constraints of the law of diminishing marginal returns of production factors and the resources and environment,it is difficult to sustain agricultural growth by relying solely on factor inputs.Continuously increasing agricultural TFP is particularly important for sustainable agricultural development.In theory,in the case of multiple outputs,in addition to changes in technological progress,technological efficiency,and scale efficiency,changes in mixed efficiency are also the driving force driving TFP growth.Structural adjustment is to change the structure of agricultural output,so that the total agricultural output changes,thereby changing the mixing efficiency,and then affecting the growth of agricultural TFP.Since 1979,the structure of China's agricultural output has changed a lot.However,the existing research on structural adjustment has promoted or inhibited the growth of agricultural TFP? How does its influence change in time and space? No clear answer has been given.Based on the aggregate quantity framework,this paper used the complete product Hicks–Moorsteen TFP index method.First,it analyzed the spatiotemporal evolution of the output structure of agriculture,plantation,and animal husbandry.Second,it figured out the impact mechanism of output structure on TFP growth.Assessing the contribution of structural adjustment to the growth of TFP in China's agriculture,plantation,and animal husbandry,the following conclusions were reached.(1)The impact of structural adjustment on China's agricultural TFP growth.The change in mixed efficiency from 1992 to 1997 improved agricultural TFP,The structural adjustment at this stage promoted the growth of agricultural TFP,while the structural adjustment in other periods did not bring about the increase of agricultural TFP.The structural adjustment of the eastern region of the region has promoted the growth of agricultural TFP in the eastern region,and the structural adjustment of the central,northeast,and western regions has restrained the growth of agricultural TFP.(2)The impact of structural adjustment on the growth of TFP in China's crop industry.The structural adjustment from 1987 to 1996 promoted the growth of TFP in the planting industry,and the structural adjustment from 2001 to 2016 had a restraining effect on the growth of TFP in the planting industry.In the region,only the structural adjustment in the middle and lower reaches of the Yangtze River has promoted the growth of TFP in the crop industry.The structural adjustment of the Northeast and Huanghuaihai regions from 1987 to 1996 promoted the growth of TFP in the plantation industry,while the structural adjustment of 2001-2016 suppressed the growth of TFP in the plantation industry.The structural adjustments in South China,Southwest,and Northwest China have not brought about TFP growth in the crop industry.(3)The impact of structural adjustment on the growth of China's animal husbandry TFP.The structural adjustments of 1984-1995 and 2007-2016 promoted the growth of TFP in the livestock industry,while the structural adjustments of 1996-2006 did not result in the growth of TFP in the livestock industry.From a spatial perspective,the structural adjustment of the Qinghai-Tibet-Mongolian-Xinmeng Plateau has promoted the growth of TFP in animal husbandry.The structural adjustment of the Loess Plateau,the southwest mountainous region,the northeast region,the Huanghuaihai region,and the southeast region have not improved the animal husbandry TFP.
