基于扎根理论的农业物流生态圈协同影响因素分析

农业物流生态圈作为一种先进的发展模式,可通过各子系统的相互协作达到双赢,解决传统农业发展面临的产业联动性差、技术水平低下、运营模式落后等问题,推动农业供给侧结构性改革。而考虑到农业物流生态圈涉及主体众多,其协同受多种因素共同作用,需要构建农业物流生态圈协同影响因素框架,以为农业物流生态圈协同研究提供指标体系。基于扎根理论这一质性研究方法,利用Nvivo11.0软件对访谈文本及相关文献资料进行深度分析,得到112个初始概念,进而由初始概念概括出39个范畴,提炼出15个副范畴,最终归纳出协同环境、协同机制、协同能力、协同意愿、扰动因素五个主范畴,形成农业物流生态圈协同影响因素框架。在这个框架中,协同环境可定义为外驱因素,协同机制、协同能力可定义为内驱因素,协同意愿可定义为中介因素,且各因素并非直接对农业物流生态圈产生影响,而是主要通过三条路径进行,其一是外驱因素→中介因素→农业物流生态圈协同,其二是内驱因素→中介因素→农业物流生态圈协同,其三是扰动因素对内驱因素和外驱因素进行调节。     

Tests of Normality of Functional Data

The paper is concerned with testing normality in samples of curves and error curves estimated from functional regression models. We propose a general paradigm based on the application of multivariate normality tests to vectors of functional principal components scores. We examine finite sample performance of a number of such tests and select the best performing tests. We apply them to several extensively used functional data sets and determine which can be treated as normal, possibly after a suitable transformation. We also offer practical guidance on software implementations of all tests we study and develop large sample justification for tests based on sample skewness and kurtosis of functional principal component scores.     

The performance of performance appraisal systems: understanding the linkage between appraisal structure and appraisal discrimination complaints

Abstract

Employee perceptions of the fairness of performance evaluations are critical to the success of any appraisal system. Research on performance management includes extensive studies on how bias emerges in the appraisal process. Despite this, there is no empirical evidence linking formal discrimination complaint filings – a key measure of bias - and performance appraisals. To close this gap, we conduct an empirical analysis using information on appraisal systems and discrimination complaints from the US federal government. Our findings suggest that agencies with better-designed appraisal systems will experience higher appraisal-related discrimination complaints, contrary to expectations. In particular, an expansion of training and voice opportunities are associated with an increase in appraisal discrimination complaints, while increased differentiation between performers is not consistently associated with complaints. For managers struggling with performance management, it may be better to spend time on improving performance-focused interpersonal communication rather than redesigning appraisal systems.     

新零售视角下贵州农资物流配送模式研究

农业是国民经济的基础,而农业生产资料的支持是农业发展的基础。在“三农”问题愈发重要的今天,农业生产资料的配送问题也随之显得十分重要。贵州省农村物流发展缓慢,传统的农资配送过程中存在着配送环节过多、配送成本过高、企业获得利润过少的问题,同时也造成了农民生产成本过高、收入低的现象。文章在分析了贵州省农资物流供应链发展现状、存在问题以及问题产生的原因基础之上,提出了“新零售”视角下建立贵州农资配送新模式。

黑龙江省农业旅游资源分布及其价值分析

[目的]对黑龙江省农业旅游资源分布及其价值进行分析和评价,以期为黑龙江省农业旅游的可持续发展提供参考和借鉴。[方法]文章对黑龙江省农业旅游资源进行分类型论述,采用层次分析法(AHP)建立黑龙江省农业旅游资源价值评价体系,根据农业旅游经营者和管理者对指标的打分值与指标权重值加权计算各类型农业资源价值指数并分析资源价值。[结果](1)根据农业资源分布、地理环境、气候天象、人文特色,将黑龙江省农业旅游资源划分为地文农业旅游区、水文农业旅游区、气候天象农业旅游区、生物生态农业旅游区、人文农业旅游区5个区域,各区域各有特色,差异性明显。(2)根据各区域资源价值指数分析看出,气候天象农业旅游区的资源价值最大,其次是地文农业旅游区,然后是水文农业旅游区和生物生态农业旅游区,人文农业旅游区的资源价值最小。[结论]黑龙江省农业旅游资源非常丰富,能够形成一个相对完整的农业旅游资源体系,具有较强的可持续发展潜力。在黑龙江省农业旅游的五大发展区域中,气候天象农业旅游区和地文农业旅游区的旅游资源价值较大。黑龙江省可以持续开发建设这一类农业旅游项目,并根据季节性与地理环境特征着力打造冰雪农业旅游。     

农机补贴的收入分配效应：效率、公平，抑或兼而有之*

农机补贴是具有门槛效应的效率增益政策，通常效率与公平如鱼和熊掌不可兼得。本文通过理论模型分析了农机补贴对农业生产及农村劳动力转移的影响；并通过工具变量法和中介变量法研究了农机补贴的收入分配效应及其作用机制。研究发现，农机补贴显著降低了农户收入的基尼系数，提高了收入分配公平性；其作用机制是农机补贴提升了农业生产效率，促进了农村劳动力转移，提高了打工收入，尤其是相对贫困农户，溢出效应对冲了门槛效应，使得农机补贴的收入分配效应兼具了效率和公平。     

The impact of reverse logistics process coordination on third party relationship quality: A moderated mediation model for multichannel retailers in the fashion industry

Multichannel retailing is a widely adopted strategy in the fashion industry. Companies in this industry find it a source of competitive advantage to invest in reverse logistics infrastructure. However, limited empirical studies investigate the enablers of the relationship quality between the retailers and their reverse logistics service providers. This study quantifies the impact of reverse logistics process coordination between retailers and logistics service providers on relationship quality. Moreover, it tests the mediating role of reverse logistics service quality and the moderating role of conflict frequency in this relationship. Data were collected through a survey using a purposive sample of 241 retail store managers from the fashion retail industry of Pakistan. For this purpose, a self-administered questionnaire was developed using a five-point Likert Scale to gauge the responses. Conditional process analysis was used to evaluate the moderated mediation model. The findings showed a significant positive impact of reverse logistics process coordination on the relationship quality with a logistics service provider, a significant positive mediation effect of reverse logistics service quality, and a significant moderation effect of conflict frequency on the indirect relationship. However, conflict frequency, contrary to the hypothesis in the study, strengthened the indirect relationship. Furthermore, the moderation effect of conflict frequency on the direct relationship was insignificant. This study will help managers better understand the best practices leading to effective management of reverse logistics processes, particularly product returns.
