This paper contributes to the literature on the relationship between city size and firm productivity by focusing on agglomeration, selection (market competition), and sorting (presence of firms with diverse productivity) effects using Chinese firm-level data for 1998–2013. Contrary to the existing literature, our parametric regression estimates from nearly two million firms show that when the selection effect is controlled, productivity advantage in big cities is reversed. This outcome is explained through a quantile regression showing the existence of left-sided sorting (inefficient firms sort themselves to larger cities) in big cities which is not captured in existing empirical literature. We further find that (1) left-sided sorting is stronger in exporters than non-exporters; (2) is also generated mainly in enterprises with high asset-liability ratios; and (3) selection has a positive effect on firm productivity, suggesting that market competition is key in an explanation of the rapid growth of big cities in China.  相似文献

科研经费间接成本是对高校开展科研活动的成本补偿,随着《政府会计制度》的实施,高校在会计核算模式、财务报告编制方面都发生了重大的变化,新制度为高校成本核算提供了制度保障。本文阐述了科研经费间接成本的构成及研究现状,梳理了从资源归集、作业中心成本计算及科研项目成本分摊的整个核算流程。根据资源消耗的不同特点,运用作业成本法和权重比例法的理论和方法,科学地对科研经费间接成本进行分类和分摊,构建了比较完整地高校科研经费间接成本核算模型。同时提出了与模型运用相配套的建议:制定具体行业的间接成本核算规定,规范间接成本的核算;构建并完善高校成本管理系统并加强财务人员的培养;根据高校自身特点,制定科研经费间接成本核算体系。  相似文献

ABSTRACT

A number of services within society are designed to improve the well-being of its members and transform lives. Some services focus on the protection and support of vulnerable members of society, for example, those suffering the effects of drug use, mental health conditions, violence or poverty. Clients of such social services may also come from minority or marginalised cultural backgrounds. Typically, social services aim to reduce disparities and enhance individual and population well-being. A major challenge for social policy-makers and social service providers is to establish and maintain constructive engagement between the social services and those they are intended to serve. Some of these vulnerable clients are deemed ‘hard-to-reach’ (HTR) by policy-makers and service providers. Yet, the transformation of lives requires the involvement of the focal actor (client) and their service or activity system, as well as the engagement of other actors, such as the social worker embedded in their service or activity system. This paper aims to further unpack a novel approach, called integrative transformative service framework. This contribution extends its conceptualisation which fuses mainly three different approaches, namely Transformative Service Research (TSR), (Cultural-Historical) Activity Theory (CHAT) and (Regulatory) Engagement Theory (RET).  相似文献

Objective To quantify the burden of osteoporosis and examine the interplay between osteoporosis and various comorbidities as it relates to patient outcomes.

Methods Data from the 2011 Japan National Health and Wellness Survey (NHWS; n?=?30 000), an internet health survey fielded to a nationally representative sample of the Japanese population were used. Only women between the ages of 50–90 years were included in the analyses (n?=?6950).

Results Compared with matched controls (n?=?404), patients with osteoporosis (n?=?404) had lower MCS scores (48.94 vs 51.63), PCS scores (45.57 vs 49.12) (all p?<?0.05). The presence of osteoporosis was associated with worse patient outcomes among those with hypertension, high cholesterol, and insomnia, among other conditions.

Conclusions The results suggest a significant quality-of-life and economic burden for patients with osteoporosis in Japan. Moreover, in a complex co-morbid environment, the presence of osteoporosis contributes more to patient outcomes than other chronic conditions.  相似文献

Current knowledge about the relationship between transport disadvantage and activity space size is limited to urban areas, and as a result, very little is known about this link in a rural context. In addition, although research has identified transport disadvantaged groups based on their size of activity space, these studies have, however, not empirically explained such differences and the result is often a poor identification of the problems facing disadvantaged groups. Research has shown that transport disadvantage varies over time. The static nature of analysis using the activity space concept in previous research studies has lacked the ability to identify transport disadvantage in time. Activity space is a dynamic concept; and therefore possesses a great potential in capturing temporal variations in behaviour and access opportunities. This research derives measures of the size and fullness of activity spaces for 157 individuals for weekdays, weekends, and for a week using weekly activity-travel diary data from three case study areas located in rural Northern Ireland. Four focus groups were also conducted in order to triangulate quantitative findings and to explain the differences between different socio-spatial groups. The findings of this research show that despite having a smaller sized activity space, individuals were not disadvantaged because they were able to access their required activities locally. Car-ownership was found to be an important life line in rural areas. Temporal disaggregation of the data reveals that this is true only on weekends due to a lack of public transport services. In addition, despite activity spaces being at a similar size, the fullness of activity spaces of low-income individuals was found to be significantly lower compared to their high-income counterparts. Focus group data shows that financial constraint, poor connections both between public transport services and between transport routes and opportunities forced individuals to participate in activities located along the main transport corridors.  相似文献

Abstract

This study examines how substitutes are selected for a fly‐angling and camping recreation activity. Results show that although people choose substitutes similar to their intended activity, the degree of similarity between substitute and original is unrelated to perceived quality of substitute. Also, both the quality of a substitute and the number of available substitutes are inversely related to the importance of an activity's attributes. The lack of a relationship between activity/substitute similarity and quality of the substitute poses problems for application of the substitutability concept.  相似文献

Abstract

Traditional cost accounting systems have been replaced in recent years in the manufacturing sector by Activity Based Costing (ABC) systems. In spite of this trend in manufacturing, ABC systems have made few inroads in the services and hospitality sector, particularly in the restaurant industry. In this study, restaurant controllers in the United States were surveyed to identify their knowledge about, and use of, ABC systems. The results show that the use of ABC in the restaurant industry is almost non-existent for a variety of reasons. However, restaurants may be an ideal setting for the application of ABC tools due to the inherent characteristics of the industry.  相似文献
