四川秦巴山区矿产资源绿色开发策略研究

四川秦巴山区矿产资源种类丰富,矿产资源的开发利用已成为经济发展的支柱产业之一,但矿业生产过程中产生了严重的矿山环境地质问题。在分析了研究区矿产资源现状的基础上,总结了四川秦巴山区油气开发和固体矿产开发中产生的环境问题,结合国内外矿产资源开发利用实例研究,提出了四川秦巴山区矿产资源的绿色循环开发策略与建议:完整的矿山环境法规是矿产资源绿色开发的根本保障;完善的规划和严格的环境评价是矿产资源可持续开发的第一要务;推进矿山相关科学技术创新是提高矿产开发利用率、矿山生态环境治理的唯一途径,最终使得四川秦巴山区矿业在促进经济腾飞的同时实现绿色可持续发展。     

京津冀协同发展下保定市建设用地对二三产业贡献的区域差异研究

作为京津冀核心城市之一,保定市土地供给与经济需求矛盾尤为突出。本文运用扩展后的柯布—道格拉斯生产(C-D)模型,测度2004-2013年保定市22个县(市)建设用地供给对二三产业的贡献,以期为保定市及各县建设用地科学管理提供依据。研究表明:2004-2013年保定市建设用地对二三产业的贡献值为12.69%,高于劳动力5.40%,低于固定资本78.47%;22个县市建设用地投入对二三产业发展贡献区域差异明显,这种差异主要受经济水平、区位条件、产业结构和资源条件等因素的影响。结论:保定市相关部门应因地制宜制定差异性建设用地供给指标,最大限度发挥有限土地资源产出水平,缓解土地供需矛盾。     

The Success Factors of Food Events: The Case Study of Umbrian Extra Virgin Olive Oil

Gastronomic events are an important part of the “Made in Italy” and a vital tool for rural development. The aim of the study is to identify the complexity of the factors that determine the success of a food event. The authors, after state-of-the-art analysis of the event marketing, formulate the hypothesis of a causal model and form a data collection during the “open oil mills” in the Umbria region. Through in-depth interviews the participants were asked to express themselves about the importance and interest attributed to some aspects directly related to the theme of the event, and finally to indicate the degree of satisfaction and the likelihood of some of their future behavior. Statistical analysis based on structural equation models allowed the authors to highlight which aspects are significant in order to confirm the assumptions made. Results provide guidance for management decisions and organization of food and wine.     

中国竹藤类产品出口潜力研究——基于引力模型的实证分析

基于引力模型,运用2007~2014年8年间中国对24个竹藤类产品贸易伙伴国的面板数据进行实证分析,结果表明:APEC的有关贸易安排对中国竹藤类产品贸易流量的影响较大,美国、日本、澳大利亚等APEC成员国是中国排名前3位的竹藤类产品进口国;贸易潜力测算结果显示中国对这3个国家均存在贸易不足,竹藤类产品贸易还有很大潜力可挖。基于此,提出应进一步加强中国与APEC成员国之间的合作交流,积极推进中国对美国、日本、澳大利亚等APEC成员国竹藤类产品出口向多样化和高质量化的方向发展,尽量选择与中国要素禀赋差异小的国家开展竹藤类产品的贸易等建议。     

The influence of entrepreneur’s personal characteristics on MSEs growth through innovation

Research in the separate areas of innovation and growth has considerably intensified in recent years. However, little scholarly attention has been paid to the entrepreneurs’ personal characteristics that might explain the growth of micro and small enterprises (MSEs) through innovation. This study examines the key entrepreneurs’ personal characteristics affecting micro and small enterprises (MSEs) upgrading, defined here as substantial growth through innovation. Six major determining types of entrepreneurs’ characteristics were identified from the innovation and the growth literature: education, work experience, gender, motivations, nationality and age. The empirical results which are based on t-tests of the differences between upgraders and non-upgraders, the linear probability model and the logit model, all suggest that work experience and motivations are cornerstones in the likelihood that an MSE will upgrade. The policy implications of this study on promoting MSEs upgrading are also discussed.     

BOT模式运作下乡村生态旅游项目的发展路径研究——以重庆市为例

乡村生态旅游是农业和旅游业发展相结合的产业,其作为农村经济发展的重要引擎,已然成为解决"三农"问题的重要渠道。重庆位于我国西南地区,农业历史悠久,旅游资源发达,乡村生态旅游发展已经初现规模。但由于重庆整体经济水平在全国处于中游,加上城市基础设施投入占去政府财政支出的大部分,因此发展乡村生态旅游项目面临资金短缺和管理不善的困境。BOT模式是私营企业参与基础设施建设,向社会提供公共服务的一种方式,在我国又被称为"特许经营权",是指政府将"特许经营权"下放给私营企业,允许其参与建设和运营公共设施项目,并通过经营和管理获得利润回报的一种营销运作模式。BOT形式适用于我国当前乡村生态旅游项目的开发和发展,对改善乡村旅游项目资金不足问题及提高项目管理水平具有明显的促进作用。但BOT模式也存在诸如规划风险、道德风险和圈地风险等现实问题,需要从政府和企业等2个角度分别采取有效措施,包括加强立法工作、加大政府监管力度和制定严格的BOT协议等。     

Financial functional analysis: a conceptual framework for understanding the changing financial system

The financial system is currently undergoing a revolution brought about by e-finance, digital convergence, new market entrants and government-encouraged competition. New market entrants such as Apple, Alibaba, Facebook and Google come from industries such as IT, retail, social media and telecoms, and, therefore, do not fit comfortably within traditional financial institutional structures. A functional perspective might provide more practical insights into this revolution; however, the functional perspective has had a limited impact. This paper will investigate the benefits and limitations of financial functional analysis; probe the underpinning principles of sociology’s structural functional analysis; revisit Merton and Bodie’s (1995) six core financial functions in relation to new entrants in the financial landscape; and, finally, argue that in the new financial environment, functional analysis provides a more coherent and explanatory framework of the financial system for students and practitioners alike.     

Balancing the risk of ‘Lazearian’ interrupters and the benefits of educational and social peers: tracing parental preferences for class-size reduction

Using Danish survey data from a choice experiment, parental preferences for class-size reduction are estimated. While parents with children in large classes are willing to pay for class-size reduction, parents with children in small classes are reluctant and even express negative utility for further class-size reduction. We interpret this as parents balancing the risk of ‘Lazearian’ interrupters and the benefits of educational and social peers when forming their preferences for class size.     

我国城乡低保标准现状评估研究

我国城乡低保标准现状如何，为社会各界广泛关注。有人认为目前的城乡低保标准偏高，有人认为目前的城乡低保标准偏低，存在一定争议。对各省份2010年到2012年的城乡低保标准进行量化分析表明，我国城乡最低生活保障标准的替代率呈总体上升趋势，大致在合理区间；但城乡之间、地区之间的差距较大，不平衡问题突出，形势不容乐观。     

Tradable water saving certificates to improve urban water use efficiency: an ex‐ante evaluation in a French case study

This paper proposes a system of tradable Water Saving Certificates to improve the efficiency of water allocation between Drinking Water Utilities at river basin level. A market institutional set‐up, inspired from recent policy developments in the energy sector, is proposed. An original analytical price‐endogenous model is developed to simulate trade intensity, equilibrium price and efficiency gains in this urban water market. The economic model is implemented in a French case study using mathematical programming. It is used for conducting an ex‐ante evaluation of trade possibilities and efficiency gains, considering different spatial restrictions aimed at controlling environmental externalities. Our modelling exercise provides evidence of the benefits of the proposed Water Saving Certificate scheme.
