Previous studies reported that primary care nurse practitioners working in primary care settings may earn less than those working in specialty care settings. However, few studies have examined why such wage difference exists.
This study used human capital theory to determine the degree to which the wage differences between dingsPCNPs working in primary care versus specialty care settings is driven by the differences in PCNPs' characteristics. Feasible generalized least squares regression was used to examine the wage differences for PCNPs working in primary care and specialty care settings.
A cross-sectional, secondary data analysis was conducted using the restricted file of 2012 National Sample Survey of Nurse Practitioners.
Oaxaca-Blinder decomposition technique was used to explore the factors contributing to wage differences.The results suggested that hourly wages of PCNPs working in primary care settings were, on average, 7.1% lower than PCNPs working in specialty care settings, holding PCNPs' socio-demographic, human capital, and employment characteristics constant. Approximately 4% of this wage difference was explained by PCNPs' characteristics; but 96% of these differences were due to unexplained factors.
A large, unexplained wage difference exists between PCNPs working in primary care and specialty care settings.
先前的研究报告指出，在初级保健环境中工作的初级保健护士从业者的收入可能低于在专科保健环境中工作的从业者。然而，很少有研究探讨这种工资差异存在的原因。
本研究使用人力资本理论来确定在初级保健与专科保健环境中工作的护士从业者之间的工资差异在多大程度上是由从业者特征的差异所驱动。采用可行的广义最小二乘法回归来检验在初级保健和专科保健环境中工作的护士从业者的工资差异。
使用 2012 年国家护士从业者样本调查的受限文件进行了横断面、二次数据分析。
使用 Oaxaca-Blinder 分解技术来探讨造成工资差异的因素。结果表明，在控制护士从业者的社会人口统计学、人力资本和就业特征的情况下，在初级保健环境中工作的护士从业者的时薪平均比在专科保健环境中工作的从业者低 7.1%。大约 4%的工资差异可以由护士从业者的特征来解释，但其中 96%的差异是由无法解释的因素造成的。
在初级保健和专科保健环境中工作的护士从业者之间存在着巨大的、无法解释的工资差异。
