Programs to improve water quality do not improve all water bodies equally. Evaluation of the benefits of such programs must account for where improvements occur and the relative magnitude of improvements that occur in different places. This study uses a choice experiment survey to explore how the value to a household of a surface water quality improvement varies as a function of (i) the distance between the household and the affected streams and rivers, (ii) the degree to which the quality of the water has been improved, (iii) how many stream and river miles have been improved, and (iv) the sizes of the affected streams and rivers. Results show evidence that value declines with distance in an approximately linear way, weak evidence that large rivers are worth more than small rivers, and no evidence that willingness-to-pay is nonlinear in either the degree of water quality improvement or the number of stream miles improved. These results indicate that it may be defensible in applied work to value small, spatially-explicit water quality improvement projects independently and then sum over projects. 相似文献

This paper examines the phenomenon of the “Solow paradox” in China using the Annual Survey of Industrial Production database and the China Customs Records dataset from 1998 to 2007. We find that China likely fell into the Solow paradox in the period 1998–2002, but the total factor productivity of information and communication technology (ICT) enterprises has achieved rapid growth since 2003. Accession to the World Trade Organization is the key reason for China to overcome the Solow paradox, that is, input tariff reduction significantly promoted the productivity of ICT firms. A series of validity and robustness checks confirmed the results. Mechanism analysis shows that input liberalization promotes the productivity of ICT firms through optimizing factor structure, importing more and high-quality inputs, and increasing research and development investment. The conclusions provide strong empirical evidence for developing countries to overcome the Solow paradox through trade liberalization. 相似文献

Many experts agree that more agricultural investment is needed in the global South to improve local food security and reduce poverty. However, there is a lack of consensus about the types of investment needed to achieve these goals. This paper contributes to the literature on large agricultural investments and corresponding business models by inventorying and analysing such investments in Kenya’s Nanyuki area. We identify four clusters of business models that differ primarily by type of production and other distinct determinants, namely: demand from markets; access to land; land tenure regime and colonial history; actors involved; biophysical context; labour availability; and governance of the value chain via private standards. The study results shed light on the factors that help or hinder implementation of large agricultural investments and shape their impacts in the context of African land use systems. The way land is accessed represents one of the most-decisive factors determining the risks and opportunities associated with such projects. We find that most investments in the Nanyuki area occur on land bought or leased from private owners. 相似文献

Our study investigates how coopetition strategies can influence hotels’ competitive intelligence (CI) practices to achieve a stronger competitive advantage. In-depth interviews were conducted with 39 hoteliers from 22 hotel groups in Hong Kong. Participating hotels employed different kinds of CI activities, though they were unaware of this concept. In particular, internal customer intelligence was added to integrated intelligence to better describe CI in the service sector. Still, investing in CI can be expensive and time-consuming since it requires hoteliers to align all insights from their respective intelligence pools toward building a holistic understanding of the results. We propose coopetition as a strategic approach allowing hotels to construct collective actions around CI without losing individual competitiveness. Actual coopetition in CI was only found between sister properties. Hence, we propose a coopetition model in which hotels can collaborate and compete in CI at an inter-organizational level via focusing on sharing open-source information and knowledge. 相似文献

人工收集和整理2012—2018年在中国市场上映的首轮院线电影信息数据,构建电影需求的嵌套logit回归模型,以新冠肺炎疫情为准自然实验,来量化突发公共事件对电影行业复产复工的影响。结果显示:第一,关于上映时间选择,在恢复营业后,如果所有因为疫情尚未上映的电影选择顺延上映能有效避免过度竞争的局面。第二,关于上映节奏控制,控制好未定档电影的上映节奏,保持适当的竞争能促进经济效益提升。其中,从11月份开始以每周两部的频率上映未定档电影的经济效益最佳。第三,关于上映方式选择,与线下播放相比,疫情期间选择线上播放能及时收回成本并有利于经济收益最大化的实现。研究结论为电影行业制定复产复工策略提供依据,为未来应对突发公共卫生事件提供参考。 相似文献

Online-to-offline (O2O) has become a rapidly growing e-commerce model worldwide, but the factors influencing consumers' purchase decision-making have not been examined well. After exploring the working mechanism of the O2O model, we extract eleven indexes of consumers' overall evaluation in the O2O model with Crawlzilla and R techniques. Social network analysis (SNA) is adopted to build social networks reflecting consumers' overall evaluation in the O2O model. Based on the modified social network and the extracted subgraph, this study (N = 768) reveals consumers' overall evaluation behavior patterns in the O2O model by calculating network density, central potential, edge betweenness. The results show that shoppers overall evaluate the eleven indexes, especially perceived product quality, online product price, promotion intensity, business reputation, and product brand, which reflects the significant associations between the indexes. Among all the eleven evaluation indexes, perceived product quality, online product price, and business reputation dominate consumers’ decision-making behavior. When making purchase decisions, consumers not only overall consider online product price, perceived product quality, and business reputation but also balance perceived product quality, business reputation, and promotion intensity. Finally, we make some suggestions on marketing strategy for e-commerce companies. 相似文献
