股权金融市场、增长方式选择与平衡增长：传统与新兴部门视角*

为探究股权金融市场对增长方式选择和平衡增长的影响，本文基于传统与新兴部门的差异，构建动态理论模型并利用“Simulink”技术进行数值模拟分析。理论分析发现股权金融市场效率对平衡增长具有增长效应且存在门槛条件，效率高于门槛值时股权金融市场发展将提高平衡增长率和创新贡献率。总体上，发展股权金融市场将促进我国平衡增长和增长方式转变，但东、西部地区存在差异，发展股权市场可以加快东部地区创新型增长而对西部地区没有显著作用。     

英国城乡规划体系及农村规划管理的经验与启示

[目的]对英国城乡规划体系及农村规划管理的发展历程、基本经验和主要特点进行归纳总结,分析其对我国当前加强农业与农村规划管理、推进城乡统筹发展、促进新型城镇化建设的启示和借鉴意义。[方法]基于赴英国进行城乡规划体系及农村规划管理与保护方面的实地考察、培训以及相关文献的综述分析。[结果]英国城乡规划体系建立缘于其解决城镇化发展过程所产生的"大城市病"问题,其发展经历了多次修改和调整,目前形成了"区域空间战略"和"地方发展框架"两级规划结构;英国的城乡规划体系十分注重对农村地区和小城镇的规划管理和保护,形成了一系列重要规则和制度。[结论]英国在城镇化发展过程中,完整地保存了传统乡村的历史建筑、风土文化和景观环境,值得充分学习和借鉴。当前,在统筹城乡发展和推进新型城镇化建设过程中,应充分发挥规划的引导作用和社会公众的参与作用,高度重视对农业与农村的保护和规划管理,同时要注重基于中国国情的再创新。     

家庭承包地“三权”分置的制度逻辑探究 ——基于制度需求与供给的视角

研究目的:阐明"三权"分置的制度逻辑,为制度供给的增量调整提供一种思路。研究方法:文献分析法、政策文本分析法。研究结果:当下农民、新型农业经营者出现新的制度诉求,既有土地承包经权营制度不足以满足该需求。承包地制度供给创新要做实承包权,辨明"三权"分置下经营权所处的位置。土地经营权的权利塑造过程应坚持物债二分法,实现物权法、合同法双重法制途径的并重。研究结论:承包地"三权"分置本质上是理论创新问题,辨清"三权"分置的制度逻辑,仍需以实践需求为出发点,新的制度供给是一个增量调整与立法跟进问题。对经营权性质的探讨有必要融入物债二分逻辑,对于短期限的土地经营权,应按照契约自由原则,实行意思主义,权利类型、权利内容经双方自由创设,对长期存续的土地经营权可实现物权化,实行物权法定主义,按照法定规格与程序流转。     

关于加快农田水利供给侧改革的几点思考

我国灌溉面积位居世界第一,主要矛盾由总量不足转变为结构性矛盾,深入推进供给侧结构性改革提上议程。针对存在的主要结构性矛盾,研究提出系统解决方案,即调整结构、去除库存、提升品质、降低成本、补齐短板。调整结构重点是严格落实"以水定地",着力以水资源、水生态、水环境承载能力倒逼灌溉面积调整;去除库存重点是依法实施"僵尸"工程降等报废,及时办理注销登记;提升品质重点是大力发展高效节水灌溉,提升灌溉服务质量;降低成本重点是深化国有灌区管理体制改革,创新"最后一公里"管理模式;补齐短板重点是坚持统分结合、重点在统的原则推进农田水利产权改革,深化农业水价综合改革,建立准确补贴机制。     

System of crop intensification for more productive,resource-conserving,climate-resilient,and sustainable agriculture: experience with diverse crops in varying agroecologies

With continually increasing demand for food accompanied by the constraints of climate change and the availability and quality of soil and water, the world’s farmers are challenged to produce more food per hectare with less water, and with fewer agrochemical inputs if possible. The ideas and methods of the system of rice intensification which is improving irrigated rice production are now being extended/adapted to many other crops: wheat, maize, finger millet, sugarcane, tef, mustard, legumes, vegetables, and even spices. Promoting better root growth and enhancing the soil’s fertility with organic materials are being found effective means for raising the yields of many crop plants with less water, less fertilizer, reduced seeds, fewer agrochemicals, and greater climate resilience. In this article, we review what is becoming known about various farmer-centred innovations for agroecological crop management that can contribute to agricultural sustainability. These changes represent the emerging system of crop intensification, which is being increasingly applied in Asian, African, and Latin American countries. More research will be needed to verify the efficacy and impact of these innovations and to clarify their conditions and limits. But as no negative effects for human or environmental health have been identified, making these agronomic options more widely known should prompt more investigation and, to the extent justified by results, utilization of these methodologies.     

Applying the counseling-learning approach to a tourism-related massive open online course

ABSTRACT

This study discusses how to apply counseling-learning (CL) principles to a particular e-learning solution for teaching a tourism-related subject via a massive open online course (MOOC). Several effective caring patterns in achieving learning-related goals and being part of a community according to the CL principles are presented and discussed using the MOOC “eTourism: Communication Perspectives” as a case study. The study underlines how the MOOC platform can act as a place for contents enjoinment and active learning. Moreover, the active role of social media for increasing the engagement of learners in the proposed activities and for developing a sense of the community is identified. In particular, Facebook and Twitter can act as places for community building and informal social interactions among learners that last beyond the completion of the course, which in turn can be a valid aid for continuing the relationships among instructors/learners and learners/learners, and for reaching new ones.

Engines of Growth in China: The Limits of Informal Institutions

Abstract:

Since the 1978 reforms, China has experienced rapid economic and social development. GDP growth has been in the double digits on average yearly, creating the fastest sustained economic growth recorded by a major economy in history. Not only did this transform the economy and society at large, China reached important milestones in terms of reducing poverty and creating prosperity in a short period of time. This article uses the conceptual framework of new institutional economics to examine China’s economic growth and how growth has been achieved largely by ‘informal institutions’ that are grounded in culture, customs, and private interactions that emerge spontaneously. The trajectory by which these informal institutions left their imprint on China’s complex economic landscape and how they can constrain future economic growth are also of central importance. After examining decentralization and risk management practices, property rights, and the legal system, we emphasize the importance of creating formal institutions necessary for long-term growth, most importantly innovation. Preliminary evidence shows total factor productivity is tapering off which may reflect the constraints of China’s institutional environment. This ought to be reversed if China is to enjoy long-term sustained growth.     

GIS-based fuzzy multi-criteria approach for optimal site selection of fire stations in Istanbul,Turkey

Fire stations play a central role in protection and response activities as part of emergency management services in cases of fire incidences. With the rising urban populations and city expansions, the demand for more fire services resultantly increases. It then becomes critical to effectively plan the location of emergency facilities to adequately service the population and ensure the protection of lives and infrastructure. This study, therefore proposes the use of the fuzzy extension of the Multi-Criteria Decision-Making (MCDM) method of Analytical Hierarchical Process (AHP), hence called fuzzy AHP, integrated with Geographic Information Systems (GIS) approach to optimally site new fire stations for the case of Istanbul region. This proposed fuzzy approach simulates the subjective expert judgements for the preferences of the six criteria assessed for fire station suitability mapping and thereby accounted for the uncertainty of crisp comparison values via triangular fuzzy numbers (TFNs). The criteria weights evaluated from this procedure were used in a weighted overlay analysis of the reclassified criteria map layers in ArcGIS to generate a fire station suitability map. These resultant fuzzy AHP criteria weights were validated using another MCDM technique, called Best-Worst Method (BWM) and found to be comparable and consistent. The criteria that had the strongest influence on the selection of sites for fire stations were identified to be: the density of hazardous material facilities (DHM), a high population density (HPD) and proximity to main roads (PMR) with associated weights of 33.3%, 24.4% and 15.2%, respectively. Based on a thorough assessment within the areas represented by class values ranging from 3 to 5 on the suitability map, a total of 34 new fire station sites were selected complementing the existing 121 fire stations. Further, a prioritization analysis from low, medium to high, was performed to plan the phases for the construction of new fire stations in view of competing budgetary needs and resource constraints. The methodology to achieve this was proposed and modelled for enhancing the decision-making process in urban fire station site selection studies.     

Dynamic efficiency evaluation of Italian judicial system using DEA based Malmquist productivity indexes

The aim of this study is the empirical analysis of the Italian judicial system, measuring its efficiency and productivity. For this purpose, in details, the Data Envelopment Analysis (DEA) and Malmquist indexes were used, since they are recognized by the current literature as successful techniques to evaluate the performance of decision making units, namely the courts of law in our field of application.The statistical data on the administration of justice in Italy, as reported in Dossier n. 11 May 2013, Senate Research Services, Research Office on Institutional Issues, Justice and Culture, XVII legislature, shows that the efficiency crisis of justice in Italy began in the 1970s of the last century, aggravating during the ‘80s, and reaching its most critical moment during the 1990s. Several studies emphasize the relevance of the effects of inefficiency upon the judicial system on the credit and financial markets.The present analysis, using data that covers a wide time span and is disaggregated at district level, has set the goal of measuring the efficiency of the individual Italian judicial offices while assessing the progress of productivity in its components, by the means of technological progress and scale efficiency. The efficiency analysis that was carried out transcends the aspect of judicial taxation, considering how the passage of time has impacted on judicial efficiency.Considering the judges and judicial administration employed, in the new, pending and finished cases during the years ranging from 2011 to 2016, the results highlighted a distinct heterogeneity among courts, depending on their geographical location. The five-year period that was considered, included the years in which the judicial geographical distribution reform entered into force, so to better comprehend how this complex reform influenced the recovery of efficiency of the judicial offices. Furthermore, by breaking down the index into change in efficiency and change in technology, this work offers a further glimpse into judiciary organization. The application of combined DEA method and Malmquist indexes for evaluating court efficiency in a large time frame showed very interesting and useful results, relevant for judicial administration.
