心理契约对基层全科医师工作绩效的影响机制:离职倾向的中介调节作用

目的 分析心理契约对基层全科医师工作绩效的影响机制,探析离职倾向在其中的中介调节作用,为基层全科医师队伍建设提供依据。方法 采用问卷调查对南京市浦口区基层医疗卫生机构的全科医师进行调研,收集其社会人口学信息,测量其心理契约、工作绩效和离职倾向水平,拟合多重线性回归模型分析作用机制和中介调节效应,验证本研究的4个研究假设。结果 基层全科医师心理契约对工作绩效存在正向促进作用(b=0.554,P<0.001)。纳入离职倾向后,心理契约和队伍稳定性对于工作绩效均存在正向促进作用(b=0.285、0.357,P<0.001)。纳入心理契约和离职倾向的交互项后,交互项的偏回归系数差异具有统计学意义(b=-0.013,P=0.006),说明低离职倾向抑制了心理契约提升工作绩效的正向作用。结论 应重视基层全科医师内在情感(即心理契约)的激励作用,采用多举措降低离职意愿,提升职业认同,避免发生“出工不出力”现象,促进工作绩效提升和基层全科医师队伍稳定。

An empirical study on the green effects of new energy vehicle promotion in the context of global carbon neutrality

In the context of global carbon neutrality,new energy vehicle promotion(NEVP)has become an important means of reducing carbon emissions.This paper constructs a theoretical model and uses panel data on NEVP in 21 countries from 2012 to 2018 to empirically examine the green effect of NEVP.The results indicate the following:(1)NEVP significantly reduces greenhouse gases emissions,and the green effect can be transmitted and diffused through a direct path.(2)Replacing fuel-fired vehicles and accelerating the end-of-life vehicle scrapping process significantly conducted the green effect,and aggravating traffic congestion was not statistically significant.(3)The transmission mechanism of the green effect is regulated by regional economic heterogeneity.In regions with better development of fuel-fired vehicles,the transmission of the green effect is subject to the elimination of fuel-fired vehicles and traffic congestion governance,and the transmission efficiency is low.However,regions with a relatively weak fuel-fired automobile industry foundation show a strong“advantage of backwardness”,and the green effect is more prominent.This means that global NEVP should be further accelerated to achieve the green effect and the goal of global carbon neutrality.
