市场和政府:扩大内需的约束条件

七次降息未能扭转通货紧缩现象,其原因在于以间接融资为主的金融市场,利率机制自发调节存在 失灵的区域,而宏观调控缺乏运作的基础,也存在盲目性。应加快利率市场化进程,促进金融市场直接融 资的迅速发展,才能有效实现币值稳定和经济增长。     

粮食安全与农业结构调整水平的协整分析*——以广东省为例

[目的]实现我国粮食安全与农业结构调整之间(即粮食增产和农民增收)关系的协调,较长时间以来是学界、政界关注的重要议题,但定量分析两者之间内在依存关系的研究一直欠缺。[方法]文章采用协整分析及Granger因果关系检验方法,以广东为例,对我国粮食安全(用粮食总产量来衡量)与农业结构调整水平之间的协整性及因果关系进行了研究。[结果]广东粮食总产量与反映农业结构调整水平的3个指标之间均存在长期均衡关系,且农作物播种面积中粮食作物面积对广东粮食总产量影响最大,每下降1%,粮食总产量下降0. 659 548%。短期内,反映农业结构调整水平的3个指标对广东粮食总产量的影响均存在波动,但由短期偏离拉向长期均衡的牵动作用均较弱。Granger因果关系检验表明农业在国民经济中的比重、农作物播种面积中粮食作物面积早期对广东粮食总产量产生单向影响,但影响程度相对较弱。[结论]提出应从农业结构调整以外的因素着手提高我国粮食安全水平,并通过调整农业区域结构去缓解我国粮食供求市场的结构性矛盾。     

湘南农业结构调整与优化的政策建设探讨

农业结构调整与优化是我国21世纪农业发展战略的必然选择,但须有强力政策支持体系。因此,必须对农业结构调整与优化政策进行准确定位,并建立与之相适应的政策目标和措施体系。作为具有相对区域优势和特殊地位的湘南农业,还应该有自己的区域政策。     

现阶段中国私营企业劳资关系调整研究

改革开放以来,我国私营经济迅速发展,为国民经济的增长做出了巨大贡献。但是,伴随私营经济的增长,私营企业劳资关系的负面影响日益明显。特别是近年来,我国私营企业的劳资纠纷频频发生,甚至出现了严重摧残民工身心的山西黑砖窑虐待工人事件。在这种背景下,调整劳资关系,提高工人的地位和待遇,成为贯彻落实科学发展观、构建社会主义和谐社会的重要任务。因此,本文以我国私营企业劳资关系为研究对象,对现阶段我国私营企业劳资关系进行了系统的研究。     

Work experiences,work adjustment and psychological well-being of expatriate employees in Hong Kong

This study replicated and extended research on expatriate work adjustment by examining the antecedents of work adjustment and its outcomes in terms of psychological well-being. Data were obtained from a nationally heterogeneous sample (N = 184) of expatriate employees in Hong Kong using a structured questionnaire. Results of regression analysis revealed role conflict to be significantly negatively related to work adjustment, while role discretion, co-worker support and work-method ambiguity (clarity) were significantly positively related to work adjustment. Of the three hypothesized outcomes, work adjustment was significantly positively related only to job satisfaction but not to quality of life and marital adjustment. Though not the focus of this study, interaction adjustment was found to be significantly positively related to quality of life. Limitations of the study and implications of the findings are discussed.     

Variations in human resource management in Asian countries: MNC home-country and host-country effects

This paper investigates the determinants of HRM strategy in a random sample of firms operating in Korea and Taiwan. Both indigenous and foreign-owned firms are studied. HRM strategy is measured in terms of the company's reliance on high-performance, versus more traditional, HRM policies and practices in several different areas, including staffing, employee influence, employee rewards and employee autonomy. Independent variables include the firm's country or region of origin (USA, Japan, Europe, Korea or Taiwan), the host country (Korea or Taiwan) and the internal culture of the firm, as measured by upper management's perception that human resources constitute a significant source of value for the organization. Pronounced differences are found across countries of origin and between the two host countries. Managerial values and various organizational characteristics that serve as control variables are also found to impact on HRM strategy.

Firm heterogeneity, productivity and spatially bounded knowledge externalities

In this paper, we argue that conceptually disentangling the ‘context versus composition’ aspects of regional growth is a multilevel issue. By applying multilevel models (also called random-effects models), we show (1) the importance of considering firm-specific characteristics simultaneously with region-specific characteristics, as we find that a large part of what is traditionally assigned to the impact of the region should be assigned to firm-specific characteristics and (2) that existing single-level methodologies can be problematic, as they are vulnerable to the charge of estimating significance levels that are too liberally assigned and promote exaggerations. This is illustrated empirically by showing that single-level approaches would lead to the conclusion that innovation spillovers are highly significant in a setting of Dutch urban growth differentials, while multilevel analyses shows less liberally assigned significance levels. We conclude that multilevel-effect models better fit research questions that combine firm and spatial characteristics simultaneously, especially because they allow firm-specific characteristics to be differently linked to their regional contexts.     

基于ARM的电压移相实验教学平台设计

本文介绍了基于ARM微处理器实现数字式电压移相与幅值调节功能,采用RAM环形队列实现电压信号波形在0～360度范围内移相,且在移相过程中保持电压波形频率不改变;并可以对移相器输出的电压幅值进行调节,输出一定的功率。该设备可以在高校继电保护及微机型继电保护实验教学中作为实验教学平台应用。
