我国农机综合作业水平影响因素的计量分析

本文针对我国较高的农机动力水平对应较低的农机作业水平的实际状况,运用统计方法,研究了农机综合作业水平与动力水平的相关性,并建立双对数模型,对农机综合作业水平的影响因素——农机动力水平(顷均耕地农机动力)、自然禀赋(可机耕地比重)、制度因素(劳均耕地面积)、经济发展水平(人均纯收入)等进行了计量分析。结果表明,四类影响因素对农机综合作业水平影响程度有大小之分,且农机动力、可机耕地比重、劳均耕地面积都与农机综合作业水平呈显著的正相关关系,农民人均纯收入与农机综合作业水平呈负相关关系。

Measurement Analysis of Influencing Factors of the Synthesized Operation Standard of Agricultural Machinery in China

Aiming at the state that the upper power of agricultural machinery is corresponding to the lower synthesized operation standard of agricultural machinery in our country, this paper studied the relativity of both by correlation analysis, then it made further measurement analysis by establishing a measurement model to identify the degree of four main factors--the power of agricultural machinery per hectare ploughed field, the proportion of machine-ploughed field, the acreage under cultivation per labor and per capita income of peasant which influence the synthesized operation standard of agricultural machinery. It turned out that the correlation between the synthesized operation standard of agricultural machinery and per capita income of peasant is negative correlation, but the correlation between the synthesized operation standard of agricultural machinery and anyone of the rest 3 factors is obvious positive correlation.
