基于组合评价法的混流生产系统运行绩效评价

在目前集装箱制造行业转型升级的背景下，以某集装箱制造公司的特箱生产系统为例，构建混流生产系统运行绩效的评价指标体系，运用组合评价法对运行绩效进行评价。借鉴平衡计分卡的分析思路，对特箱生产系统的生产管理给出了相关的决策建议。此研究成果对其他制造型混流生产系统具有实际的指导意义。     

经济增长与不平等对我国农村脱贫时间的影响

选择FGT贫困指数和脱贫时间指数，利用世界银行公布的我国农村贫困线和收入分配分组数据。对比分析了1981年-2005年以来的农村贫困变化趋势。研究发现，农村贫困状况虽然总体上呈缓解趋势，但在脱贫时间指数的构成中，由于不平等所延长的脱贫时间，无论从绝对量还是相对量上都明显提高，这说明收入分配的恶化已经成为反贫困的严重障碍，这种变化趋势值得高度关注。     

南京市休闲农业空间差异及其社会经济影响因素分析

[目的]休闲农业在促进产业融合、带动过农业、农村发展方面发挥着重要作用,分析其空间分布特征及其社会经济影响因素,为休闲农业的健康可持续发展提供一定参考。[方法]文章以南京市为例,通过文献查阅法了解南京市休闲农业的资料、相关研究成果,结合实地调查法确保南京市休闲农业景点的真实性,采用空间结构分析法分析休闲农业空间分布差异,相关分析法分析其影响因素。[结果]南京市6个区的最临近指数均小于1,空间分布呈凝聚型,其中浦口区的分布密度最大,为0.035个/千km~2。休闲农业分布与地区GDP、农业产值、旅游发展水平显著相关,与产业结构、城镇和农村居民消费水平相关,但不显著,说明目前南京市第一、二、三产业融合有待进一步加强,休闲农业产品仍有提升空间。[结论]南京市休闲农业发展受社会经济发展的影响,因此需要基于休闲农业资源,差异化发展,同时协调发展休闲农业服务供应链,促进产业融合,完善休闲农业相关政策,耦合侧供给改革共同发展。     

The contribution of Western fast food to fast-growing body mass in China

The westernization of Asian countries has led to the rapid expansion of Western-style fast-food restaurants, which are believed to be fueling an unprecedented rise in body mass in these countries. This study tests this belief using longitudinal data from China. Exploiting the opening of a Western-style fast-food restaurant in a particular community, we conduct a transition analysis to make a more convincing causal interpretation than the standard cross-sectional or fixed-effects approach. Considering several measures of fatness, we find no robust evidence of Western fast food having a substantial effect overall, but there is some indication of effect heterogeneity.     

江苏旅游业发展效率及对策研究——基于超效率DEA和Malmquist指数分析

文章利用超效率DEA模型和Malmqulst指数模型分别测算了江苏13市2001-2012年旅游业发展的静态效率与动态效率。结果显示:江苏旅游业静态效率保持先降后升的态势,从2001年的0.848下降到2006年的0.611,后又上升到2012年的0.824,12年间效率均值为0.726。各市旅游业效率存在显著的地区差异,且呈现逐步扩大的趋势。江苏旅游业动态效率(TFP)年均变化值-0.6%,增长主要来源于技术进步而不是规模效率的作用。在以上研究的基础上,提出提升江苏旅游业效率的对策,为旅游业持续、高效、健康发展提供理论参考。

Analyzing the welfare‐improving potential of land in the former homelands of South Africa

This article contributes to the debate on the role of land in reducing poverty in rural South Africa. It uses the year of arrival in the former homelands as an instrument for land access and size. This identification strategy is based on the fact that African households were forcibly relocated to the homelands during the apartheid. Due to increasing population pressure, later arrivals were less likely to be assigned land. The results show that land has a large positive effect on household welfare. Because the homelands are relatively disadvantaged areas, these results provide a lower bound for the positive effects of land on household welfare.     

基于动态面板数据模型分析FDI的环境效应

外商直接投资在对中国经济增长起到积极推动作用的同时,我们也不可忽视其可能会对我国环境造成的影响。文章通过构建环境污染综合指数,并且以东中西部为三个横截面建立动态面板数据模型来分析外商直接投资对各个地区环境的影响。结果显示,外商直接投资和东部中部地区的环境污染指数之间有正相关关系,和西部地区的环境污染指数之间是一个负相关关系。     

南京江北新区新型城镇化发展质量评价与提升路径

文章构建了由31项指标组成的新型城镇化综合发展质量评价指标体系,运用AHP层次分析法和熵值法,选择19个国家级新区中2018年经济总量排名前十的新区进行定量对比分析,并结合民生幸福建设群众满意度问卷调查分析,对南京江北新区新型城镇化发展质量进行综合评价。研究表明:(1)南京江北新区新型城镇化整体发展处于中上游水平,与发达新区相比存在一定差距,产业结构亟需优化;(2)发展增长方式、资源利用率、环境保护类指标明显落后;(3)科教文卫、居民生活等指标具有比较优势。文章最后提出新型城镇化提升路径为加快生态环境和公共服务建设,积极提升科教和生态示范效应,做大做强主导产业,促进城乡特色均衡发展和推进以人为核心的新型城镇化。     

Bank competition,concentration and financial stability in the Turkish banking industry

This paper analyzes the impact of competition and concentration on bank stability in the Turkish banking industry over the period 2002–2012. The Boone indicator and the efficiency-adjusted Lerner index are used as proxies for competition, while the non-performing loans (NPL) ratio and Z-scores are used as proxies for bank stability. The main results indicate that competition is negatively related to the NPL ratio but positively related to the Z-score. The results further indicate that greater concentration has a positive impact on the NPL and a negative impact on the Z-score. We also use a quadratic term of the competition measures to capture a possible non-linear relationship between competition and stability. The results show that the coefficient of the quadratic term is negative for the NPL model and positive for the Z-score model. Overall, our findings provide support for the competition-fragility view.
