农民问题的核心是农民的权益保障问题。论文对成都统筹城乡改革中有关农民权益保障,包括经济权益、社会权益、政治权益的基本情况进行了调研分析,在经验归纳的基础上指出,在坚持中国共产党及其政府作为制度的整体设计者与公共资源的主体供给者前提下,从农民的权益诉求出发,落实并保障农民的权益。  相似文献

依据绩效感知服务质量度量模型(SERVPERF)以旅游者的旅游知觉为标准对旅行社产品进行评价。评价系统将旅行社产品细化并以旅游产品消费过程为基础,以官方机构为主体,运用网络认证码为保障确保结果的真实性。旨在为旅行社产品质量评价、监督提供可行、可靠的网络评价系统。通过评价使旅游信息更加对称,并对旅行社产品质量改进起到督促作用,对实现旅游企业间的良性竞争具有重要的现实意义。  相似文献

文学作品来源于生活现实,不同时期的文学作品从各个不同的侧面记录了当时的社会经济面貌,唐诗作为中国古典文学的瑰宝,是中国古代经济不可忽略的研究对象。以白居易的名篇《卖炭翁》为例,可分析以长安为代表的唐代分工与交换的发展状况、货币制度、财产权和契约制度,并可根据基本的经济规律,推断出古代人民勤劳简朴,却难得温饱的经济学原因。  相似文献

The market as a mind is the implicit premise in any discussion on whether the market is rational or not. Still, its implications, in terms of ontology and epistemology, are hardly understood. In particular, this paper defines the market's version of the mind-body problem and labels it as finance's “hard” problem. Its denial by modern finance causes this dominant paradigm to fail in dealing with reality in general and to produce incomplete investment knowledge in particular. Finally, as part of facing up to this problem, this paper offers a glimpse at a practical approach which may enrich investment research.  相似文献

Objective:

The objective for the research was to evaluate the direct healthcare costs for Crohn’s disease (CD) patients categorized by adherence status.

Methods:

Adult patients with ≥1 claim for infliximab and ≥2 claims for CD who were continuously insured for 12 months before and after their first infliximab infusion (index date) were identified in a 2006–2009 US managed care database. Patients were excluded if they had rheumatoid arthritis claims, received infliximab billed as a pharmacy benefit, or received another biologic drug. Patients were categorized as being either adherent or intermittently adherent to infliximab using a pre-defined algorithm. Total and component direct costs, CD-related costs, rates of surgery, and days of hospitalization were estimated for the 360-day post-index period. Propensity weighted generalized linear models were used to adjust the cost estimates for potential confounding variables.

Results:

The total propensity weighted cost for infliximab adherent patients was $40,425 (95% CI?=?[$38,686, $42,242]), compared to $41,082 (95% CI?=?[$38,163, $44,223]) for the intermittently adherent (p?=?0.71). However, adherent patients had lower total direct medical costs, exclusive of infliximab, that were $13,097 (95% CI?=?[$12,141, $14,127]) compared with $20,068 (95% CI?=?[$17,676, $22,784]) for intermittently adherent patients as a result of substantially lower hospital and outpatient costs (p?Conclusions:

Greater drug-related costs for infliximab adherent patients were offset by lower costs from hospitalization and outpatient visits. These findings indicate that adherent patients have improved clinical outcomes, at a similar aggregate cost, than patients who are only intermittently adherent to therapy.  相似文献

ABSTRACT

Analyzing the participation of Hausa women in religiously influenced nongovernmental organizations (NGOs) devoted to development work provides critical insights into the complex intersection of gender, religion, class, culture, and politics and economics. Based on interviews with leaders and employees of various NGOs, including community-based organizations (CBOs), in Kano, Nigeria, in 2010–11, this in-depth case study provides important examples of how various types of NGOs navigate political pressures when it comes to funding; it recognizes the understudied importance of women's labor contributions in the context of the development apparatus in Africa; it highlights the role of women as progenitors rather than benefactors of economic development; and it illustrates the unique role that faith-based organizations (FBOs) can and do play in terms of reaching certain marginalized segments of the population.  相似文献

如何利用临街样点地价推算区片平均地价及基准地价始终是城镇基准地价评估的一个难点。文章利用赤峰市的实际调查数据,分别采用临街贡献率和面积加权两种方法推算区片平均地价,并采用回归分析方法探讨区片价与临街地价之间的关系,结果证明两种方法所推算的区片平均价是基本一致的,而且区片价与临街地价之间呈“反S”曲线关系。  相似文献

Since Benford’s law is an empirical phenomenon that occurs in a range of data sets, this raises the question as to whether or not the same thing might be true in terms of the Chinese income distribution data. We focus on the first significant digit (FSD) distribution of Chinese micro income data from the 2005 Inter-Census sample, which corresponds to 1% of Chinese population and other micro income data from the China family panel studies (CFPS) and Chinese General Social Survey (CGSS). We use information theoretic-entropy based methods to investigate the degree to which Benford’s FSD law is consistent with the FSD of Chinese income data and our findings suggest consistency between the Chinese FSD income distribution and Benford’s distribution. The close connection between the two distributions has implications for the quality of the sample of Chinese micro data.  相似文献

本文构建了一个两部门DSGE模型,同时考虑了创新扩散的一般规律(“S型扩散”)与企业绿色技术创新扩散的独特作用(节能作用和减排作用)。基于人口老龄化的预测,模拟随着企业绿色技术创新扩散的波动,经济系统所做出的响应。结果表明:经济变量对于企业绿色技术创新扩散的波动呈现出不同的响应路径,其中资本存量的响应具有滞后性;资本报酬率为首的相关经济变量对于正向冲击的响应出现了“翘尾效应”。最后,本文给出了稳定、正向引导市场预期和在资本市场采取预调机制的政策建议。  相似文献
