“倒挂型”土地利用总体规划的耕地保护效果评价

研究目的:揭示"倒挂型"土地利用总体规划与耕地保护效果之间的关系,以期为国土空间规划的编制提供参考。研究方法:倾向值匹配法。研究结果:(1)耕地"倒挂型"规划对耕地面积净变化的影响具有统计显著性,2006—2008年,耕保指标"倒挂型"规划使耕地面积净变化量平均减少2.270万hm2;(2)2010—2016年,耕保指标"倒挂型"规划使耕地面积净变化量平均减少0.496万hm2;(3)建设用地"倒挂型"规划对耕地面积净变化量并无显著影响。研究结论:在省级政府耕地保护责任目标考核的制度环境下,耕地"倒挂型"规划对地方政府形成一定压力,促使各级政府采取措施加以应对,从而使得"倒挂型"规划在一定程度上降低了耕地净减少量。

Nested identities as cognitive drivers of strategy

Research Summary: Organizations face tensions to conform to industry norms for legitimacy yet differentiate for competitive advantage when implementing strategies. We suggest this tension is due to and resolved through organizations’ cognitive negotiations of multiple levels of identity. Through an inductive study in the recreational vehicle industry, we find that organizations concurrently draw on identities at the organizational, industry, and strategic group levels to formulate and enact specific competitive actions. Specifically, we find that organizational identity relates to decisions on product offerings; industry identity relates to downstream strategy; and strategic group identity relates to upstream strategy, firm boundaries, and expansion mode. Our findings highlight the importance of strategic group identity and inform a grounded model describing how organizations draw upon different levels of identity to influence strategy. Managerial Summary: Many managers experience tensions of differentiating their firms’ competitive actions from rivals, while conforming with industry norms and practices. In this article, we argue that a manager can navigate these tensions by understanding their firm, strategic group, and industry identities and how these identities interrelate. Through a qualitative case study of the U.S. recreational vehicle industry, we show that each level of identity influences different competitive actions, with firm identity connected to product offerings, industry identity related to managing downstream distribution, and strategic group identity related to firm boundary and acquisition strategies. Overall, strategic group identity is the most critical for managers as this level filters how they view competitors and provides the rules of competition.     

Bandwagon and leapfrog effects in Internet implementation

This paper underscores the critical relationship between innovation adoption and innovation implementation, particularly how two contrasting effects—bandwagon and leapfrog—relate to organizational Internet diffusion. Bandwagon effects, adopting a technology due to fad and fashion, accelerate adoption but often lead to ineffective technology implementation. Leapfrog effects, however, attenuate adoption and often lead to effective technology use relative to early adopters. Drawing on and combining related Malaysian hospitality studies, this paper illustrates these two effects and extends the literature by showing that early, and late, adoption can relate positively to successful Internet implementation. In addition, the findings complement and question literature suggesting that business websites evolve through predictable linear patterns, and that adopter categories differ in innovation implementation styles.     

How middle managers manage the political environment to achieve market goals: Insights from China's state‐owned enterprises

Research summary: Although the middle management literature has identified various bridging roles performed by middle managers in the market environment, it is relatively vague about whether and how they manage the political environment to achieve market‐related goals. In an inductive field study of four large state‐owned enterprises based in mainland Communist China, operational middle managers were found to take an active role in dealing with political actors to achieve market efficiency in their local environments, performing two distinct bridging strategies. Our field study suggests that middle managers are better equipped than their bosses (top executives) as well as their subordinates (frontline employees) to perform the bridging function between competing market and political imperatives in various local settings. Managerial summary: For firms that operate in diverse geographies, it is challenging for a handful of top executives to deal with numerous political actors. This burden could be shared with operational middle managers, who play a bridging role by drawing on their operational knowledge and local networks. Our research on middle managers who work under the scrutiny of political actors in China found that they bridge market and political ideology by conveying common features that seem legitimate to both. They also bridge market goals and political actors with personal affect. Compared to top executives and frontline employees, middle managers have unique advantages in performing these bridging functions. Firms can enhance their strategy execution ability by training middle managers in dealing with political actors in diverse contexts. Copyright © 2016 John Wiley & Sons, Ltd.

Consumer sorting and hedonic valuation of wine attributes: exploiting data from a field experiment

This article uses a novel experimental approach to measure consumer willingness to pay (WTP) for wine attributes. We invited customers of a local supermarket who had selected a bottle of wine to purchase to participate in a valuation experiment. Integrating their original wine choice into the experiment, each participant evaluated six alternative wines, generating a rich set of data on willingness to pay and consumer characteristics. The data from the experiment allow us to compare standard shelf price‐based wine attribute valuation estimates with estimates using WTP data and an increasing amount of information about individual consumers. The full model employs individual fixed effects to estimate WTP parameters without bias from consumer sorting or supply side influences. Our WTP estimates for wine attributes differ markedly from previous attribute value estimates. Consumers in our sample display clear and stable preferences for wine varieties, but less clear preferences for appellations. Our results suggest caution is needed in using market prices to estimate parameters of the consumer valuation function for product attributes.
