县域是完成农民就近城镇化、实现城乡要素跨界配置、促进一二三产融合发展最为基础的空间单元.在一些户籍人口规模大的县域,县城公共服务设施的提标扩面是保障城镇化质量的关键,而教育设施至关重要.通过剖取皖北太和县重点研究,发现该类县城呈现出非常明显的基础教育驱动人口集聚的城镇化景观,现象背后折射出农业转移人口以家庭为单位用时空成本换代际流动的诉求,即该类城镇化的动力机制.农村学生家庭在乡城迁移过程中发生了从"半耕半工"向"半工伴读"的分工模式转变,家庭成员因就近陪读和远距离务工相结合而呈现横跨乡村—本地县城—异地大城市的时空离散.以教育为媒介,上一代在付出巨大时空成本的同时,下一代进行着"城市性"的生活方式、思维模式的社会习得,积累融入社会阶层体系的文化资本,乃至以考学作为通道,实现基于代际之上的城镇化.研究对于具体规划实践中,认识县域城镇化的特征趋势、扩大县城公共服务设施布局中教育资源的供给,提供了更为坚实的实证基础. 相似文献

Drawing upon the research in institutional theory and comparative capitalism, the present study investigates how cross-national differences in the political, business, and economic institutional contexts of the United States, Italy, and Japan are associated with the ways in which companies in each of these countries prioritize and engage in their stakeholder engagement activities (SEAs). Using Porter and Kramer's framework, which classifies corporate social responsibility (CSR) activities as falling into four categories (good citizenship, mitigating harm from value chain, transforming value chain activities, and strategic philanthropy), we investigate how companies in the United States, Japan, and Italy prioritize and engage in these four SEAs. An analysis of data collected from 340 companies across these countries reveals that while companies in each of these three countries undertake the four types of SEAs, the prioritization and prevalence of the four types of SEAs vary from one country to the other, in ways that align with the prevailing institutional contexts of each country. The results contribute to a more nuanced understanding of why and how companies' approaches to CSR differ across countries. From a practitioner's perspective, the findings highlight the cultural specificity of CSR, implying that despite the global nature of CSR, the implementation of CSR needs to be tailored to a country's context. 相似文献

This paper develops a platform‐based influencing factors model which considers value perception, risk prevention measure, non‐default experience, trust and incentive gap, to better examine the impact of platforms on investors’ satisfaction and lending intention based on the Chinese market. The results reveal that the first four factors positively influence the satisfaction of the investors, while the incentive gap has a negative impact, and there is a positive association between investors’ satisfaction and lending intention. Some specific features of China’s online lending market are identified, which provides valuable insights for online lending platforms and the government. 相似文献

In this study, an epsilon-based network data envelopment analysis is employed to construct assessment mechanisms for government performance. Moreover, performance indicators of two dimensions of tax collection efficiency and financial effectiveness are measured. We propose a vector autoregression model in which all economic variables are regarded as dependent variables to address the disadvantages of traditional regression model. The conclusions are as follows: (a) measures of tax collection efficiency deteriorated, whereas those of financial effectiveness improved. (b) In an impulse response analysis of the model, an increase in government-published land values produced significantly increased tax collection efficiency. 相似文献

当前小体积远端射频单元(Remote Radio Unit,RRU)主要是皮站级别的Pico-RRU,其重量和体积仍然难以满足掌上型的要求。为此,采用高集成度的AD9361芯片来实现长期演进(Long Term Evolution,LTE)宽带收发信机功能,配合时钟同步模块、放大器模块和控制接口电路等一起构建低成本的掌上型RRU。主要解决了基于AD9516的时钟同步、低相位噪声设计和高灵敏度接收机设计三个技术难点,成功实现了掌上型、高性能、低成本的设计目标。整个RRU样机尺寸为18 cm×10 cm×2 cm,质量约500 g,量产成本千元以内。测试表明,该RRU下行误差向量幅度(Error Vector Magnitude,EVM)小于3%,优于3GPP要求的8%;10 MHz带宽时上行接收机灵敏度优于3GPP要求的-93.5 dBm。 相似文献

This paper investigates convergence patterns among China's provinces using GDP data for the period 1952–97. We analyze convergence behaviour on the basis of Markov chains proposed by Quah (1993 ) and the generalized entropy decomposition proposed by Shorrocks (1980, 1984 ). Both sets of results show similar evidence of convergence within the pre‐defined geo‐economic sub‐regions, but no evidence is found of convergence between the sub‐regions. This finding has important policy implications for regional economic development in China. JEL classification: C33, E20, O47. 相似文献

随着知识经济时代的到来,人力资源会计变得日益重要,其中人力资源价值确认与计量居于其核心地位,但是,由于人力资源本身的复杂性、不确定性,至今没有形成一种统一的人力资源会计价值计量模式.本文试图从西方经济学要素需求理论角度来构建一种人力资源会计价值计量模式,以求在理论上就其可计量性做一下初步探讨. 相似文献

我国入境旅游发展现状、趋势预测及策略分析 总被引:5,自引:0,他引:5
通过对1997—2006年我国旅游服务贸易出口国际市场占有率指数、旅游服务贸易竞争优势指数和显示性比较优势指数的比较,可以看出我国旅游服务贸易国际竞争力尚不强。结合1978—2007我国历年入境旅游人次和外汇收入数据,通过建立时间序列模型,可以对未来五年我国入境旅游发展趋势进行预测。建议根据我国入境旅游消费结构特征,采用从宏观上实行差异化引导等策略。 相似文献
