湖北省耕地利用集约度评价及分析

本文对影响耕地集约利用的因素进行了分析,确定了耕地集约利用的评价指标及权重,对湖北省1998年～2005年的耕地集约水平进行计算。研究表明,湖北省近年耕地利用集约度总体呈下降趋势;各市县的耕地集约利用水平较均衡,区域差异不明显,仅有十堰和神农架林区因退耕还林面积较大,且耕地种植条件较差,集约水平较低;并分析湖北省耕地利用集约度下降的原因,给出相关建议。     

乡村生态旅游促进新型城镇化的实证分析--以西安市长安区为例

在生态资源富集又邻近大城市的乡村地区发展乡村生态旅游,能够有效地促进新型城镇化、助推新型旅游小城镇的形成。文章在界定核心概念并进行理论机理分析的基础上,以西安市长安区为例,对其2002—2014年间乡村生态旅游与新型城镇化之间的关系进行实证检验,结果表明：二者确实存在高度的正相关关系,且前者是后者的重要原因。因此,应采取有力措施发展这些地区的乡村生态旅游：第一,进一步加大政府对乡村地区基础设施的投资,彻底实现城乡公共产品供给的均等化;第二,引导民间资金、技术、管理等有序合理、规模适度地投入乡村生态旅游业;第三,务必加强乡村生态旅游业发展过程中的环境监管等。     

Do‐no‐harm versus do‐good social responsibility: Attributional thinking and the liability of foreignness

Research summary: The efforts of multinational corporations to be socially responsible do not always engender positive evaluations from overseas stakeholders. Drawing on attribution theory, we argue that two heuristics guide stakeholders in evaluating firms' social performance: foreignness and the valence of firms' social responsibility. We provide evidence from a field study of secondary stakeholders and an experimental study involving 129 non‐governmental organizations. Consistent with attribution theory, the liability of foreignness is minimized when firms engage in “do‐good” social responsibility (focused on proactive engagement creating positive externalities) but is substantial when firms engage in “do‐no‐harm” social responsibility (focused on attenuating negative externalities). In online supporting information, Appendix S1, we demonstrate that these evaluations have consequences for whether stakeholders subsequently cooperate, or sow conflict, with firms. Managerial summary: There is no guarantee that efforts to be socially responsible will improve multinational corporations' relations with overseas stakeholders, such as customers, governments, and activists. In a field study and an experiment, we unpack when foreign firms suffer from harsh stakeholder evaluations. Foreign firms especially suffer from harsh evaluations when they conduct “do‐no‐harm” CSR rather than “do‐good” CSR. Stakeholders attribute the motive for foreign firms' do‐no‐harm CSR to managerial interests and shareholder pressures, perceiving a wedge between managers and owners (who may be unmotivated to reduce the negative impacts of their business activities) and local stakeholders (who bear the social costs). A practical implication is that foreign firms gain more from highlighting do‐good rather than do‐(no)‐harm CSR initiatives. Copyright © 2015 John Wiley & Sons, Ltd.     

Bankruptcy Prediction for Chinese Firms： Comparing Data Mining Tools With Logit Analysis

China＇s capital market is different from that of the US in economic, political, and socio-cultural ways. China＇s dynamic and fast growing economy for the past decade entails some structural changes and weaknesses and as a consequence, there are some business failures. We propose bankruptcy prediction models using Chinese firm data via several data mining tools and traditional logit analysis. We used Chinese firm data one year prior to bankruptcy and our results suggest that the financial variables developed by Altman （1968） and Ohlson （1980） perform reasonably well in determining business failures of Chinese firms, but the overall prediction rate is low compared with those of the US or other countries＇ studies. The reasons for this low prediction rate may be structural weaknesses resulting from China＇s fast growth and immature capital market.
