Total Factor Productivity Assessment of Tourism Industry: Evidence from China

This paper adopts the Malmquist Index and panel data model to measure and test the spatial–temporal evolutionary characteristics and the factors that affect total factor productivity of China's tourism industry from 2001 to 2009. The results show the following: there is a trend of growth in the total factor productivity of China's tourism industry, and technological progress is the dominant factor that affects total factor productivity changes, which indicates that the growth pattern of China's tourism industry has changed from a pattern driven by input factors to a pattern driven by technology; the spatial pattern of the total factor productivity of China's tourism industry has changed from a spatial pattern dominated by provinces with a low productivity to a spatial pattern dominated by provinces with a high productivity; the total factor productivity of China's tourism industry is mainly affected by the levels of economic and service industry development.     

Company–Nonprofit Partnerships,Negative Spillover,and Response Strategies

This study explored whether, in the context of a company–nonprofit partnership, there are negative spillover effects when a crisis strikes a partner organization and what effective response strategies to such a crisis would be for the principal organization. We conducted an online experiment (N = 445) with a 2 (duration of partnership: long-term vs. short-term) × 4 (response strategy: denial, ending partnership, continuing partnership, vs. no response) between-subject design, with two no-crisis control groups. The results confirmed the existence of negative spillover effects; when respondents were exposed to crisis information about a partner organization, their attitude toward the principal organization became less favorable. We found that, regardless of the partnership’s duration, announcing a decision about the partnership—either ending the partnership or continuing the partnership—was not effective in restoring the principal organization’s image. Denial strategies, however, significantly improved the image of the principal organization, up to its precrisis level. We discuss the practical and theoretical implications.     

蛇纹石尾矿浸出液中金属的萃取分离

采用溶剂萃取法对蛇纹石尾矿酸性浸出液中的金属进行了萃取分离的研究。采用2-乙基己基膦酸单2-乙基己基酯(P507)萃取剂萃取浸出液中的Fe(Ⅲ)、Al(Ⅲ)和Ca(Ⅱ),使其与Ni(Ⅱ)、Mg(Ⅱ)分离,考察了P507浓度、皂化率、浸取液酸度及反萃剂浓度对各金属离子分离的影响,获得了最佳实验条件。之后用环烷酸提取Ni(Ⅱ),使其与Mg(Ⅱ)分离,考察了环烷酸萃取剂浓度、萃取级数、萃取时间及反萃剂浓度、相比和反萃级数对镍提取分离的影响。结果表明在适宜的萃取条件下可实现各金属之间的分离提纯,为蛇纹石尾矿的再利用提供了一条途径。

Foreign Entry and Firm Advertising Intensity: Evidence from China

This paper investigates the determinants of advertising intensity at the firm level by focusing on the role of foreign entry. In a monopolistically competitive market with heterogeneous firms, we show that foreign entry affects the expected advertising intensity of domestic firms through its impact on the cost of resources, brand image, and productivity spillovers and its impact on firms’ exit behaviour. Then, using comprehensive firm-level data from China’s manufacturing sector between 2005 and 2007, we test this hypothesis and find that foreign entry significantly affects advertising intensity.

Social media affordances in entry‐level employees’ socialization: employee agency in the management of their professional impressions and vulnerability during early stages of socialization

This study examined how entry‐level employees interacted with social media during three stages of organizational socialization. They navigated between four different media affordances (persistence, editability, visibility, and association) while experiencing them as both enabling and constraining in different socialization stages. Qualitative interview data analysis revealed during anticipatory socialization, job applicants realized visibility and persistence in relation to institutional and individualized socialization. During encounter, new employees managed personal and professional life boundaries carefully against the association and visibility affordances. Although some participants used both public and enterprise social media for obtaining job‐related information and understanding coworkers and company culture, during metamorphosis, most interviewees adopted passive information seeking strategies and experienced a paradoxical tension between the enabling and constraining affordances of social media. Findings are discussed with regards to employees’ exertion of agency in managing their professional impressions and coping with high levels of uncertainty and vulnerability during early stages of socialization.     

基于PSM-DID模型的政策对试点企业经营绩效的影响评价研究——以供应链创新与应用试点政策为例

近年来,我国政府积极推进供应链领域政策的制定与发布,如何更好地评估既有政策带来的绩效成为政府进一步完善供应链相关政策的关键。本文选取商务部“供应链创新与应用试点”政策(商建函[2018]142号)作为研究对象,并构建双重差分倾向得分匹配(PSM-DID)模型,将试点企业经营绩效中的盈利能力指标ROA作为被解释变量,利用Stata15.0对2015~2019年5年间覆盖3494家样本企业的面板数据,共15278个样本进行处理计算,以此对该政策实施对试点企业经营绩效的影响效果进行评价。结果表明:2018年开始实施的供应链创新与应用试点政策,对试点企业的经营绩效ROA有着显著的正向促进作用。此外,企业规模、企业的资产负债率、托宾Q值和企业固定资产投资比率都对ROA有显著影响。其中企业规模和托宾Q值对ROA有正向影响,资产负债率和固定资产投资比率对ROA有负向影响。
