长三角城市群新型城镇化与生态效率耦合协调及驱动因素研究

随着我国迈入高质量发展阶段,城市可持续发展的一个重要难题就是城镇化与生态保护的协调问题。以长三角地区作为研究区域,利用熵权法和非期望产出SBM模型定量测度2005—2018年新型城镇化水平和生态效率;借助耦合协调模型,测度二者的时空格局及相对发展状态;通过构建Tobit模型,研究长三角地区新型城镇化与生态效率耦合的驱动因素。结果表明:(1)从综合发展水平来看,长三角地区新型城镇化、生态效率均呈上升趋势,但两个子系统之间发展不平衡;(2)从协调发展水平来看,长三角地区新型城镇化与生态效率的耦合协调度均值在0.38~0.72之间,整体处于上升趋势,经历了“拮抗—磨合—协调”三个阶段,且空间分异特征显著;研究阶段前期,发展水平多为新型城镇化超前,后期发展比例趋向均衡。(3)从驱动因素来看,资源聚集能力、经济发展水平、区域创新环境、社会促进能力对耦合协调度产生显著的积极影响,工业化水平及对外开放程度则对耦合协调度产生显著的负向影响,且地区间的驱动因素差异较为显著。

全球化背景下的湛江市域发展战略研究

全球化加速发展，对区域发展产生了深远影响，也引起了湛江市周边区域环境发生着变化，环北部湾经济圈的崛起、“大珠三角”和“泛珠三角”的建设、中国一东盟自由贸易区的建成以及西部大开发战略的实施。文章以此为背景，分析了湛江市的区域地位(包括区位条件、区域优势和区域地位)，对湛江市域发展战略进行了思考，提出战略目标和重点，主要在培育产业集群、构建区域创新系统、建立区域协调机制以及实施点轴带动的不平衡发展战略。     

THE EMERGENCE OF FREELANCER COOPERATIVES IN SOUTH KOREA

This paper examines freelancer cooperatives that have recently emerged in South Korea. In particular, it investigates the reasons why freelancers have established cooperatives and what conditions are required for freelancer cooperatives to increase their work. A review of the extant literature on the manner in which freelancers have to organize, as well as case studies regarding freelancer cooperatives, shows that freelancer cooperatives have emerged in order to reduce members' job uncertainty and to reduce time variance of projects assigned to a freelancer. Based on an analysis of freelancers’ organizational characteristics relative to entrepreneur cooperatives and worker cooperatives, we propose that the freelancer cooperatives are a hybrid between entrepreneur cooperatives and worker cooperatives. This paper also proposes the conditions required for development of freelancer cooperatives and suggests how those are distinguished from traditional entrepreneur cooperatives.     

小微企业资金约束供应链中的协调融资——基于核心企业的功能价值视角

小微企业资金流瓶颈带来的供应链短板效应不仅成为制约其自身创新发展的桎梏,而且威胁到所在供应链的稳定性和竞争力。根据供应链中核心企业在协助小微企业解决资金约束问题过程中发挥的协调功能,提出了供应链融资协调模式,并对协调模式解决小微企业融资问题的作用机理进行了分析。针对协调模式运作中可能存在的权力配置和运作效率问题,进一步从共同财产权、信息共享和利润分配等方面探讨了使协调模式良性运作的机制设计。     

当前我国国内横向税收竞争的实证分析

目前我国理论研究的不足阻碍了对现实生活中各类税收竞争问题的有效治理。为此,着眼于我国国内横向税收竞争的实践,对其进行总结和归类,剖析其背后的体制与制度原因,评价其经济效应,并由此提出促进我国国内横向税收有序发展的政策措施是必要的。     

The Coordination Role of Stress Tests in Bank Risk‐Taking

We examine whether stress tests distort banks' risk‐taking decisions. We study a model in which a regulator may choose to rescue banks in the event of concurrent bank failures. Our analysis reveals a novel coordination role of stress tests. Disclosure of stress‐test results informs banks of the failure likelihood of other banks, which can reduce welfare by facilitating banks' coordination in risk‐taking. However, conducting stress tests also enables the regulator to more effectively intervene banks, coordinating them preemptively into taking lower risks. We find that, if the regulator has a strong incentive to bail out, stress tests improve welfare, whereas if the regulator's incentive to bail out is weak, stress tests impair welfare.     

我国金融机构的组织规模、空间分布与效率改进

金融机构的组织规模和网点分布密切相关,规模扩张通常意味着分支机构网点的空间扩张.金融业是关系密集型行业,关系在不同的金融产品和服务中的重要性是不一样的,其经营的经济规模也是不一样的.个人保险类金融产品关系性最低,其经营也最接近普通消费品的营销原则;公司类产品最具有关系性,其经营最依赖于银企双方的关系.金融产品和服务中关系型的经济规模较小,非关系型的经济规模较大.金融机构经营领域是不同关系类型的金融产品和服务的业务集合,这很容易使金融机构过度膨胀.通过机构专业化、组织集团化和配送一体化可以改变这一特征并提高金融机构运营效率.     

Policy instruments for curbing CO2 emissions: The case of the Netherlands

Taxes may seem to be the most attractive instrument for curbing the emissions of carbon dioxide. This paper, however, argues that environmental taxes involve a number of serious complications — especially in an open economy riddled with market imperfections like the Netherlands. Therefore, a wide-ranging policy mix is called for. As far as households and sheltered sectors are concerned, regulation can continue to play a major role. Within the context of unilateral policies aimed at exposed sectors, the combination of subsidies and voluntary agreements may be more cost effective than the tax instrument.This paper was prepared for a conference on Energy Taxation in Europe organized by the Stichting voor Economisch Onderzoek (SEO) and held on December 13, 1991 in Amsterdam, the Netherlands. The author would like to thank Sijbren Cnossen, Jarig van Sinderen and one anonymous referee for helpful comments on an earlier draft.     

绿色普惠金融与乡村振兴耦合能否助推经济发展？

基于2011—2020年中国30个省（自治区、直辖市）的相关面板数据,利用耦合协调度和空间回归模型,分析绿色普惠金融与乡村振兴耦合协调发展水平并进一步探讨其对经济的助推作用。结果表明：绿色普惠金融与乡村振兴之间存在耦合协调机制;无论在经济空间还是地理空间中,某一地区的耦合协调度均可以促进本地及周边地区经济增长;在东、中、西部区域中,耦合协调度的经济效应具备空间外溢性和地区异质性。基于此,提出在全国范围内整体提升耦合协调度、在不同区域内立足区域实际进行精准施策的建议。
