新疆农业生产结构历史与现状实证分析

农业结构,也称农业产业结构,是指一定地域（国家、地区）的农业各产业部门内部的组成及其相互之间的比例关系。广义农业结构指种植业、牧业、林业和渔业比例和相互关系。狭义农业结构指种植业内部包括谷物、棉花、油料、蔬菜、水果等属于现行我国统计制度中的各项种植业类别。新疆农业结构发展趋势形成以下特点：农作物种植面积逐年增加;粮食播种面积逐年下降;棉花产业成为支柱产业;林果业发展前景广阔等。     

Employee acceptance of digital monitoring systems while working from home

Digitalisation and COVID-19 led to an expansion of remote work arrangements, raising the question of whether and how employers should monitor remote workplaces. However, before the implementation of monitoring methods, it is important to consider employees' acceptance of this approach. Therefore, we contribute to current research on electronic performance monitoring by empirically investigating employees' evaluations of performance monitoring at home. This paper presents an analysis of how certain monitoring technologies for work-from-home arrangements are perceived as undesirable and whether other job aspects can compensate for these unattractive monitoring components. Using an experimental factorial survey design, German employees evaluated remote work arrangements with randomly varying characteristics. We show that respondents accept a certain degree of monitoring at home but increasingly reject monitoring systems as they become more invasive. However, in some cases, the negative impact of monitoring at home can be mitigated by certain incentives, such as money or the purpose of monitoring.     

刑事证据制度的权力伦理成本

刑事证据是案件事实的载体。现代刑事证据制度体现了国家权力意志,而使其呈现权力本质以及伦理性需求的制度性特征。从国家权力伦理的视角看,刑事证据制度需注意国家权力伦理成本。     

FDI引进与中国区域制度变迁的互动机制研究——来自中国各地区的经验证据

对我国各区域2004年和2008年8个制度因素指标的实证比较分析发现,我国东、中、西部地区制度变迁呈梯度递减趋势,西部地区制度变迁严重滞后;对我国各地区8个制度因素2001—2003年当期、滞后一期、滞后二期24个因子与FDI引进关系进行的计量经济检验表明,FDI在我国三大区域的聚集与制度因素呈显著的相关性;利用1984—2008年数据对制度因素与FDI的因果关系检验表明,制度变迁与FDI的引进存在双向因果关系。根据实证研究结论,各地区在FDI的引进中要重视制度软环境的建设,尤其是西部地区应主动进行强制性制度变迁,通过制度环境的改善吸引FDI流入,进而以FDI来带动西部地区的制度演进,最终形成制度变迁和FDI相互促进、相互推动的良性循环,以此缩小地区差距,实现区域经济的协调和均衡发展。

House Money Effects in Public Good Experiments

Are decisions in economics experiments distorted because the money subjects risk comes from the experimenter rather than their own pockets? There is some evidence that people receiving small, one time “windfall gains” have a higher marginal propensity to consume them, and when doing so, exhibit greater risk-seeking behaviour. This has been found in individual decision making experiments when anticipated wealth effects have been controlled, and labelled the “house money effect.” In public good experiments, house money effects could be driving the high levels of voluntary contributions commonly observed. This possibility is tested by comparing VCM contribution rates when subjects supply their own endowments with those when endowments are provided, while holding constant the distribution of promised earnings. No evidence of house money effects is found, suggesting that use of “free” initial money endowments does not distort subsequent contributions in VCM environments.     

区域农业项目投资评价方法研究

文章根据农业项目投资的特征性,充分考虑农业区域的优势所在,在借鉴和总结前人研究成果的基础上,用D-S证据推理的原理和模糊数学的理论来研究区域农业项目的投资评价。这种方法避免了以往凭主观臆断来选择项目的麻木性,减少了不必要的损失,使农业项目的投资决策更为科学合理。
