工会承诺、组织承诺和员工绩效——被企业所有制类型跨层次调节的中介模型

基于我国工会维稳与维权的双重角色,要发挥工会预防劳资矛盾激化的功能,并履行集体劳动争议代表的责任,需要研究工人是否对工会有承诺,以及这种承诺与组织承诺和员工绩效的关系。鉴于不同所有制企业工会的差异,文章基于角色理论、认知理论和交换理论,针对员工的工会承诺、组织承诺和绩效之间的关系展开研究,研究中使用了32家企业共709个员工样本的嵌套数据建立了不同所有制企业跨层次被调节的中介模型进行假设验证。研究结果表明：工会承诺正向影响组织承诺,组织承诺在工会承诺和员工绩效关系中起中介作用,并且该中介作用在公有制企业中较强,在非公有制企业中较弱。文章最后对实证分析部分进行了讨论,并指出未来研究方向。     

Estimating a Local Food Waste Baseline

ABSTRACT

This article estimates the amounts of food that is discarded, diverted, and landfilled in Minnesota by comparing and applying approaches and statistics from selected national, regional, and local studies. Our preferred estimates suggest 2.1 million tons of food is discarded in Minnesota, of which 60% is diverted through recovery and recycling efforts. The remaining 834 thousand tons are landfilled. This landfilled amount, considered as “food waste,” is smaller than the 1.3 million tons calculated using the ReFED (2016) methods, but its estimated distribution across the food supply chain is similar. Residential losses account for the largest proportion of food waste landfilled (43%). The processing and manufacturing stage discards the largest proportion of food (36%), but generates the smallest amount landfilled because of a high diversion factor. The range of estimates obtained from various methods highlights the complexities in choosing appropriate assumptions, factors, and datasets when calculating food waste baseline amounts.     

地方政府债务对工业资本配置效率的非线性影响效应——基于动态面板平滑转换回归PSTR模型的检验

经济新常态下,提高工业资本等要素配置效率是实现经济向高质量增长转变的必然要求。本文在政府主导、投资驱动的工业发展模式下,结合地方债务压力和金融发展差异门限变量,在非线性框架下运用动态面板平滑转换回归模型实证检验地方债务规模与工业资本配置效率的渐进演变关系。研究发现,适度的地方债务规模有助于提高资本配置效率,但随着债务压力增加,举债对资本配置的正效应逐步减弱并产生负效应。究其原因,适度举债能补齐工业基础设施短板,压低土地成本,对工业发展产生杠杆效应,从而提高资本配置效率;但过度举债推升财政风险,占用信贷资源并强化企业融资约束,造成资本配置低效率。此外,研究发现,地方信贷规模提升,能缓解举债的融资约束,促进工业行业间的资本流动;而工业金融深化程度提高,能增强市场竞争机制在要素配置中的作用,缓解举债造成投资错配,从而增强资本配置效率。以上分析结果表明,地方政府举债应更理性、适度、规范。     

基于干扰矩阵的高密WLAN场景下集中式功率控制

针对高密无线局域网（WLAN）场景中系统干扰严重导致吞吐量降低的问题,提出了一种集中式动态发射功率控制算法（CDTPC）。接入控制器（AC）依据接入点（AP）定时上报的信道扫描报告和邻居报告建立干扰矩阵,通过分析干扰矩阵确定干扰源AP集和覆盖漏洞AP集,并对干扰源AP和覆盖漏洞AP进行动态功率控制,在保障覆盖的情况下减小WLAN系统内干扰、提高网络整体吞吐量。仿真表明：在高密WLAN场景中,使用CDTPC算法进行功率控制前后各AP吞吐对量均有所提高,系统整体吞吐量提高了41.5%.     

论中国地方保护主义的特点和效应

地方保护主义在产品市场和资金市场上有不同的形式和特点,具有产业针对性和地区针对性。不同地区的保护程度、保护手段和保护方式也不一样。从短期和局部来看,地方保护主义是有一定益处的,但从长期和全局来看,它会导致效率的降低、分配的不公平乃至整个国家经济的衰败和没落。     

我国农民转移就业的空间区位选择

我国富余农业劳动力转移的途径,主要表现为就地转移和异地转移。鉴于过去30年我国八成以上的农民转移到城市不仅没有带来城乡居民收入差别的缩小。反而导致城乡差别明显扩大。孕育了难以转型的农民工特殊社会群体,今后应当把转移农民就业渠道的重点放在发展乡镇企业,壮大县域经济上,即实行农民的就地转移。     

Environmental Multi‐dimensionality and Staff Localization in Multinational Enterprises: The Case of Korean Firms

The person–environment fit theory posits that the term “environment” can be defined at different levels. This study delineates two environmental dimensions (strategic and organizational) and empirically examines the potential moderating effects of two strategic factors (intra‐ and inter‐regional diversification) on the relationship between two organizational factors (subsidiary ownership and host‐country experience) and MNE subsidiary staffing composition. The results indicate that strategic and organizational dimensions have impacts on subsidiary staffing composition. This study also finds that the interaction effects between strategic and organizational factors are significant only when there is congruence between demands from different environmental dimensions.     

The Role of Ownership in Managing Interfirm Opportunism: A Dyadic Study

We extend research on transaction cost theory that shows that vertical integration enables firms to protect their investments in exchange relationships better than market mechanisms. However, extant research finds ownership to exacerbate, rather than limit, exchange partner opportunism. Hence, the purpose of this study is to investigate conditions under which ownership can be effective for constraining an exchange partner's opportunism. Using matched dyadic data for 296 hotel brands, we conduct multi-level hierarchical linear modeling and identify conditions under which common ownership limits hotel opportunism. Findings indicate that ownership can limit hotel opportunism when brand headquarters can easily monitor the hotel's activities.     

The Effects of Public Venture Capital Investments on Corporate Governance: Evidence From IPO Firms in Emerging Markets

This study examines the impact of public venture capital (hereafter PVC) investments on corporate governance of initial public offering (hereafter IPO) firms in emerging markets. Using data collected from Taiwan PVC investments during 1996–2005, we analyse three corporate governance features in IPO firms: earnings management, board characteristics, and excess control by controlling shareholders. We find that PVC‐backed firms use fewer accounting accruals in their IPO financial statements than non‐PVC‐backed firms. This result suggests that PVC‐backed IPO firms engage in less earnings management than non‐PVC‐backed IPO firms. We also find PVC‐backed firms tend to set up their boards with fewer non‐independent directors and supervisors at IPO. This result indicates that PVC‐backed IPO firms have better board structures than non‐PVC‐backed IPO firms. Finally, we find that controlling shareholders are less likely to exert excess control in PVC‐backed firms than in non‐PVC‐backed firms. Overall, our results indicate that PVC investments add value to new IPO firms not only in financing their capital needs but also in creating better corporate governance structures in emerging markets.     

Intercorporate Ownership,Taxes, and Corporate Payout Choices*

This paper examines whether corporate payout choices (dividends or share repurchases) are associated with intercorporate ownership in a firm. Using the System for Electronic Document Analysis and Retrieval (SEDAR) and the Inter‐Corporate Ownership (ICO) database from Statistics Canada, I find that intercorporate ownership is positively associated with a firm’s propensity to pay dividends and negatively associated with a firm’s propensity to repurchase shares. The findings are robust to the endogeneity of intercorporate ownership and the inclusion of various control variables such as firm size, risk, liquidity, growth, and profitability.
