Abstract: Working time fragmentation is a common challenge faced by scientific researchers. However, this question has not drawn enough attention from researchers. What is the current situation of working time fragmentation of scientific researchers in China? What are the main factors influencing their working hours to be fragmented? Based on a nationwide sample survey data, this paper analyzes the current situation and influencing factors of the fragmentation of working hours of researchers in China by using the methods of descriptive analysis and OLS regression analysis. The results show that researchers in China have a strong perception of work time fragmentation. Personal characteristics such as gender, age and time management ability; social role characteristics such as work-family relationship, administrative position and professional title; and work characteristics such as work unit type, working hours and work autonomy have a significant impact on the work time fragmentation of researchers. Specifically, men, older researchers and those with lower time management ability have higher level of working time fragmentation. The more balanced the work-family relationship leads to a lower degree of fragmentation of working hours. Administrative positions and professional titles are positively correlated with the degree of time fragmentation. The degree of time fragmentation of scientific researchers in colleges and universities is significantly higher than that in other work units. The average daily working hours are positively correlated with the degree of time fragmentation, while the work autonomy is negatively correlated with the degree of time fragmentation. Finally, based on the research and analysis, the paper puts forward some policy suggestions to reduce the fragmentation of working time.

摘要： 工作时间碎片化是科研人员常面临的处境却少有研究者关注。我国科研人员的工作时间碎片化现状如何？什么因素造成他们的工作时间碎片化？基于一项全国性抽样调查数据，运用描述分析和OLS回归分析的方法，对我国科研人员工作时间碎片化的现状及其成因进行了研究。研究发现：当前我国科研人员有较强的工作时间碎片化感知，科研人员的性别、年龄、时间管理能力等个人特征、工作-家庭关系、行政职务、职称等社会角色特征，以及工作单位类型、工作时长以及工作自主性等工作特征均对科研人员工作时间碎片化有显著影响。具体而言，男性、年龄较大者和时间管理能力较低者的工作时间碎片化程度更高；工作-家庭关系越平衡，工作时间碎片化程度越低，行政职务、职称则与时间碎片化程度呈显著正相关；高等院校的科研人员时间碎片化程度显著高于其他单位同行，日均工作时长与时间碎片化程度呈显著正相关，工作自主性则与时间碎片化程度呈显著负相关。最后基于研究分析提出了降低工作时间碎片化程度、保证科研人员科研时间的政策建议。
