生态旅游视域下的岷江上游贫困山区生态安全评价

[目的]构建科学合理的评价指标体系,准确评价生态旅游影响下的区域生态安全状况,是推动少数民族山区实现旅游资源环境与区域社会、经济协同发展的前提和基础。[方法]以岷江上游贫困山区为例,应用灰色系统理论与熵值赋权法相结合,基于压力—状态—响应模型,构建生态旅游视域下的区域生态安全评估指标体系,并将评估指数与经济收入状况及贫困人口分布进行空间耦合。[结果](1)区域当前处于较安全水平,生态旅游开发适度;(2)综合评估指数与城镇居民可支配收入增长率、旅游收入对国民经济增长的贡献率呈正相关,且城镇居民在旅游开发中受益与机会较农牧民多;(3)综合评估指数与贫困人口比重呈负相关,与农牧民纯收入增长率没有必然联系。[结论]区域脱贫能够改善当地的生态安全状况,适度生态旅游开发是区域脱贫的有效手段,但应注重扶持农牧民在旅游业中的参与度,增加其旅游收益。     

管理层权力、并购效率与股价崩盘风险

本文聚焦中国A股上市公司,取2007-2016年为主要的窗口期间,通过样本研究,对管理层权力与股价崩盘风险的关系进行实证检验.进一步地,本文以商誉及对应的商誉减值构建并购效率的衡量指标,将其作为调节变量对管理层权力与股价崩盘风险的关系进行深度探讨.通过模型构建、回归与分组统计,本文得到三个方面的结论.第一,管理层权力的增大对股价崩盘风险具有正向推动作用;第二,上市公司高溢价确认商誉后又大额计提减值,会降低并购效率,进而触发股价崩盘风险;第三,并购效率的提高,会使管理层权力与股价崩盘风险正相关的显著性得以抑制.     

Beyond symbolic and substantive: Strategic disclosure of corporate environmental information in China

Under increasing regulatory pressure to disclose environmental impacts, corporate environmental information disclosure (EID) is becoming more prevalent. However, the motives for EID and disclosure approaches (i.e., symbolic or substantive) remain controversial. Using a sample of data for 742 listed manufacturing firms in China across 3 years, we provide evidence to show that the level of EID is significantly positively associated with a firm's advertising intensity and that firms in moderately competitive industries have a higher propensity for adopting an EID‐based differentiated strategy than firms in stronger or weaker competitive industries. We also find that firms that are more sensitive to environmental issues strategically understate their environmental impact when directly facing consumers. Our results suggest that the implementation of corporate EID is strategic and that firms have strong market motives, even under regulatory pressure to demonstrate legitimacy. We discuss this study's contributions to research on EID theory and implications for strategic EID management.     

The heterogeneous relationship between board social ties and corporate environmental responsibility in an emerging economy

Firms in emerging economies are faced with multiple, incompatible institutional forces in their environmental activities. Which of these forces will be dominant and instantiated within an organization is partly determined by the social relationships that a firm maintains with external actors. This paper investigates the relationship between board social ties and the level of environmental responsibility undertaken by firms in China, an emerging economy, by categorizing board social ties into three types in terms of the three isomorphic forces in the institutional field (coercive, normative and mimetic). Drawing on institutional and agency theories, using a sample of listed firms in environmentally sensitive industries, and a generalized least squares regression method, the results provide empirical evidence that ties that are linked to coercive and normative forces (i.e., political organizations and universities) are related to a higher level of environmental responsibility; however, those that are linked to mimetic forces (i.e., industrial peers) have a negative association with environmental responsibility, which is mitigated by CEO power. These findings suggest that the heterogeneous effects of board social ties on environmental responsibilities experienced by firms in a context of environmentalism are at an early stage.

考虑物流管理专业实践教学的特性,从实践环节、创新与创业、管理机制、教学团队等方面构建了实践教学指标体系,并运用模糊综合评价法进行评价分析。研究结论表明,毕业实习、毕业论文、学科竞赛、创新与创业项目对物流管理专业实践教学的影响较大。     

知识重叠、知识库特性与创新绩效

以往研究着重探讨重叠/非重叠知识在技术并购中的创新效应，然而在测度知识重叠时仅关注到数量属性而忽略了质量评估。因此，构建一个新的理论框架，利用国家知识产权局2008-2018年专利授权数据，分析217家中国机械制造企业352次国内技术并购案例，探索知识库中重叠、非重叠知识数量和质量属性对并购后创新绩效的影响。结果表明，高质量重叠知识对并购后的企业创新绩效具有正向影响，而高质量非重叠知识则有负向影响。同时，探讨知识数量对并购后创新绩效的影响。研究结果强调了知识重叠对企业获取外部知识的重要性，对企业技术并购实践具有借鉴作用。     

美国休耕制度及其对中国耕地休耕制度构建的启示

[目的]对美国休耕制度进行解读,并通过对制度文本的系统梳理和对比分析,为中国休耕制度的构建提供参考坐标。[方法]采用文献分析法和对比分析法。[结果]通过文献解读发现:(1)美国休耕立法经历了初步确立、快速发展和调整完善3个阶段;(2)美国休耕制度的政府补贴具有多元的特性,包括土地租金、成本分摊、技术援助、额外奖励和税收抵扣;(3)美国在实施休耕制度时强调计划与市场结合;(4)美国休耕制度的重心最终落脚于实现有机农业转移。[结论]根据这4项研究发现,中国在构建耕地休耕制度的过程中:首先,应逐次建构以休耕为主要内容的法律法规体系;其次,在结合多方财政系统的基础上,建立多元化、差异化、动态化、奖惩结合的休耕补贴机制;再次,需要计划和市场的有机结合,强化计划安排的同时激励农户自觉参与休耕,主动提升耕地地力;最后,休耕制度重心的落脚点应与有机农业发展的趋势相契合。     

Blockholder Exit Threats and Financial Reporting Quality

Recent theoretical and empirical studies suggest that blockholders (shareholders with ownership ≥ 5 percent) exert governance through the threat of exit. Blockholders have strong incentives to gather private information and sell their shares when managers are perceived to underperform. To prevent blockholders from selling their shares and the firm from suffering a stock price decline, managers align their actions with the interests of shareholders. As a result of the greater manager‐shareholder alignment, managers' actions are more likely to be in shareholders' best interest, and consequently there is less need for managers to manipulate earnings. Consistent with these predictions from economic theory, we find evidence that as exit threat increases, firms have higher financial reporting quality. Theory also predicts that the impact of blockholders' exit threat on financial reporting quality (FRQ) should increase as the manager's wealth is tied more closely to the stock price, and this is what we find. Our study contributes to the research on the impact of shareholders on FRQ and to an emerging literature on the impact of blockholders in financial markets. Blockholders play an important role in managers' reporting outcomes through their actions as informed investors.     

政府创新投入可以促进市场创新投入吗——基于我国内地63所教育部直属高校科技创新数据的实证研究

高校是我国重要的创新研发主体,高校经费主要来源于政府和市场,这两种异质性研发创新投入关系值得关注。选取2005-2018年我国内地63所教育部直属高校科技创新数据,采用面板VAR模型和个体固定效应模型,从动态和静态两个方面对高校科技创新投入中政府创新投入与市场创新投入的关系进行实证检验。结果发现,在高校科技创新活动中,政府创新投入对市场创新投入存在积极影响,这种促进作用存在两期左右的滞后期,且只在短期内显著;从长期看,政府投入对市场投入的促进作用不显著。     

制度理论与高阶理论整合视角下创业制度环境如何影响企业创新绩效

转型经济下企业创新绩效差异不仅来源于创业制度环境,而且受到高层管理者心智模式的影响。为探讨创业制度环境对企业创新绩效的作用机制,对制度理论和高阶理论进行整合,引入创业导向作为中介变量,CEO自恋作为调节变量。运用问卷调查法对北京、吉林、甘肃、重庆、山西和福建等地385家高新技术企业进行实证分析,结果表明：在创业制度环境对企业创新绩效的影响过程中,创业导向起显著中介作用;CEO自恋在创业制度环境与创业导向之间发挥正向调节作用,并正向调节创业导向在创业制度环境与创新绩效之间的中介作用。相关结论丰富了制度理论和高阶理论研究成果,可为企业提升创新绩效提供借鉴。
