本文利用中国29个省份20年的面板数据,探讨了人口结构变化对储蓄、投资和经济增长的影响。我们将人口结构指标引入传统的经济增长模型中,并用固定效应模型和SYS-GMM计量方法分别测算其对储蓄、投资和经济增长的效应。考虑到老年抚养比在经济增长方程的内生性,我们还将滞后30年的就业人数比率作为工具变量来识别老年抚养比对经济增长的因果效应。结果显示老年抚养率对储蓄、投资和经济增长存在显著的正相关。人口增长率对储蓄和投资有着负相关,但对经济增长没有影响。工作年龄人口比率对储蓄率存在负相关,对投资和经济增长存在正向影响但估计的回归系数不显著。在加入其它制度和人口变量之后回归结果依然稳定。 相似文献

For right-censored data, the accelerated failure time (AFT) model is an alternative to the commonly used proportional hazards regression model. It is a linear model for the (log-transformed) outcome of interest, and is particularly useful for censored outcomes that are not time-to-event, such as laboratory measurements. We provide a general and easily computable definition of the R2 measure of explained variation under the AFT model for right-censored data. We study its behavior under different censoring scenarios and under different error distributions; in particular, we also study its robustness when the parametric error distribution is misspecified. Based on Monte Carlo investigation results, we recommend the log-normal distribution as a robust error distribution to be used in practice for the parametric AFT model, when the R2 measure is of interest. We apply our methodology to an alcohol consumption during pregnancy data set from Ukraine. 相似文献

In this paper, the limit distribution of the least squares estimator for mildly explosive autoregressive models with strong mixing innovations is established, which is shown to be Cauchy as in the iid case. The result is applied to identify the onset and the end of an explosive period of an econometric time series. Simulations and data analysis are also conducted to demonstrate the usefulness of the result. 相似文献

Chan CK. Hong Kong: workfare in the world's freest economy Int J Soc Welfare 2011: 20: 22–32 © 2009 The Author(s), Journal compilation © 2009 Blackwell Publishing Ltd and the International Journal of Social Welfare. Workfare was introduced in many countries to suppress welfare dependency and reduce social security expenditures. However, workfare was launched in Hong Kong when there was only a relatively small social security budget and its citizens still strongly adhered to the ideologies of self‐reliance. It was found that workfare has performed several functions in Hong Kong. First, by forcing unemployed claimants to give up benefits, Hong Kong has been able to save on social security expenditures. Second, workfare has combined with Hong Kong's semi‐democratic polity so that extremely stigmatising welfare measures have been implemented. Third, it has pushed poor citizens into the labour market without having any protection over wages and working hours. Thus, the combination of workfare and a semi‐democratic polity has successfully suppressed Hong Kong's welfare demands and strengthened its self‐help spirit. As a result, Hong Kong's minimal social security scheme and its low tax policy have been maintained. 相似文献

From Transitional to Permanent Uncertainty: Employability of Middle‐aged Workers in Hong Kong 下载免费PDF全文
Raymond K.H. Chan 《Asian Social Work and Policy Review》2016,10(3):358-374
Since the 1990s, Hong Kong has experienced increasing economic uncertainty. Middle‐aged workers, who often have little formal education and limited skills, have been the first casualties of economic restructuring. Initially, their unemployment was considered transitional. Limited government‐sponsored retraining programs were expected to improve their employability. Subsequent economic crises, however, have undercut the hopes of both workers and policy‐makers. Despite improvements in the job market since the mid‐2000s, the belief that unemployment was transitional has been replaced by a permanent state of uncertainty and consequent anxiety. Flexibility is considered the key to sustaining economic growth, and would relieve the insecurity and anxiety associated with unemployment. Policies have been modified, but they are still based on a narrowly defined concept of individual employability, which consolidates the sense of uncertainty. To address the factors contributing to the perception of permanent uncertainty among middle‐aged workers, we advocate a pragmatic approach that takes reference from the notion of flexicurity to mitigate this sense of uncertainty. 相似文献

This study investigated hope as a protective factor buffering the relationships between parenting stress and well-being among a sample of parents identified at moderate to high risk for child maltreatment. Two hundred parents were recruited from a nonprofit organization providing secondary and tertiary child maltreatment prevention programs. Results of the analyses showed that parental stress was negatively associated with subjective and emotional well-being. Hope was positively correlated with well-being and negatively associated with parenting stress. Hierarchical regression analyses showed that hope had a significant incremental relationship to well-being and that the negative effects of parenting stress fell below statistical significance. These findings provide preliminary support for hope as a coping resource social workers can target when working with parents in the prevention of child maltreatment. 相似文献

This article adopts a processual and relational approach to study food remembrance and investigates how different ways of appropriating food reveal the politics of identities in Hong Kong. It examines how food memories reveal relationships between the past and the present, reflect epochal transformation, and mark changing identities of various groups of people through new ways of appropriations. It takes the case study of pancai, a special banquet food for the villagers in the New Territories of Hong Kong, to examine the relationships between food and identities. This article investigates how pancai is remembered, popularized, and reinvented with different variations and embodies shifting meanings for the New Territories inhabitants as well as other Hong Kong people in changing socioeconomic and political environments. Pancai has been imbued with multiple layers of significance, involving linkages between local and national, emigration and Chineseness, urbanization and rural heritage, as well as decolonization and identity politics. As identities are by nature negotiable, situational, and fluidic, pancai's multiple layers of meanings correspond to different levels of identities—identities of the New Territories inhabitants, the rest of the Hong Kong people, and the mainland Chinese. 相似文献

Research findings on comorbidity and pathological gambling are non–existent in Chinese communities. The objectives of this study were to: (a) determine the prevalence of comorbid mood and adjustment disorders among pathological gamblers seeking treatment in Hong Kong; (b) compare demographic profiles and clinical features in pathological gamblers with and without comorbid mood and adjustment disorders; and (c) explore the association and temporal relationship between pathological gambling and comorbid mood and adjustment disorders. Assessment instruments included demographic data, BSI, SCID-I, ASI and LIFE-RIFT. Results showed that about two-thirds (63.7%; n = 128) of 201 participants reported lifetime comorbid psychiatric disorders. Most common comorbid disorders were mood disorders (29.4%; n = 59) and adjustment disorders (20.9%; n = 42). Pathological gamblers with comorbid mood or adjustment disorders showed more severe levels of psychopathology, impairment in psychosocial functioning and gambling problems. This study is important because it is the first scientific comorbidity study among pathological gamblers in a Chinese context. 相似文献

Research by Barley, Meyer and Gash (1988) showed that the publication of Peters and Waterman's In Search of Excellence (1982) coincided with culture becoming a popular and acceptable topic for organization theorists. This helped establish the dominance of a conception of culture that proffered an instrumental view of the relation between managerial practice and management knowledge, Barley, Meyer and Gash (1988) suggested. They saw this as a relatively recent occurrence. While we do not deny the possibility of the instrumental relation as depicted in Barley, Meyer and Gash (1988), we do not concur with their judgement that the study of culture is a relatively novel interruption of previously more academic concerns. On the contrary, we suggest that, while the relationship between practice and knowledge is borne out by a genealogical analysis of culture, the time period for such analysis should be drawn both more widely and more deeply to be an adequate test of Barley, Meyer and Gash's (1988) hypotheses. We argue that the relationship postulated in the hypothesis supported by their research - that academic research on culture has increasingly been prejudiced by instrumental concerns that developed in the lead up to, and in the wake of, the 'excellence' studies - defies social science traditions. We show this by enlarging the canvass of culture. The purposeful use of organizational culture as a management tool returns culture to those origins revealed by genealogical analysis that uncovers its etymology and sociology. 相似文献

This paper contains our reflections about our experiences in employing a capacity building model for training social workers to conduct community development work in rural China. Unlike the conventional approach to social work practicum, our approach advocates an educational practice of capacity building; not only for local people and learners, but for educators as well. It stresses that the educator should assume a non‐expert role in relating to his/her students so that the students will do the same with local people. We challenge the concept of the social work educator as an expert because it gives a teacher the power and authority to dominate students, which disempowers students during the learning process. In the same vein, we challenge the desire of social work students to become experts in rural development, which in turn disempowers local people from taking charge of the future direction of their lives in rural China. The capacity building approach subscribes to a critical pedagogy that calls for a re‐invention of self by challenging tradition and culture, and by developing academic knowledge, the habit of inquiry and critical curiosity about society, power, inequality, and social change. 相似文献
