地理标志农产品产业化的减贫增收效应——基于山西省110个县的实证分析

[目的]已有研究只注意到了地理标志产品的减贫增收效应,却并没有说明地理标志产品减贫增收效应的条件。文章旨在分析地理标志产品促进农村发展的条件和路径。[方法]在理论上分析了地理标志产品促进农村发展的两条主要路径,并使用山西省110个县的县级数据和计量模型,采用OLS和加权OLS回归方法,分析了地理标志农产品及产业聚集度对农民人均收入和农业人均生产总值的影响。[结果]拥有地理标志农产品是县级层面地方政府的自然优势,但只有形成一定的集聚程度并达到产业化才能形成区域竞争优势,并对当地的农民收入有减贫增收效应。[结论]认为地理标志产品的减贫增收主要有两条路径,首先,区域竞争优势对与该农业产业相关的经济资源有很强的集聚效应,加快了当地农业产业集群的形成,为实现产业化经营提供了一个新的"高位平台",从而促进农村减贫的进程;另外,推动当地农业的品牌化发展是地理标志提高农民收入促进农村减贫的另一条重要途径。     

广西加工贸易发展的比较优势研究

随着经济全球化进程的加快,国际分工不断发展,国际化生产日益扩张,加工贸易成为国际贸易的重要方式.广西可以充分利用东盟自由贸易区的建立、西部大开发战略的实施等机遇,发展加工贸易,促进广西经济的增长.本文从广西加工贸易发展的区位优势、资源优势和政策优势等方面阐述了广西加工贸易发展的比较优势,为广西利用上述的优势发展加工贸易提供了理论支持.     

企业行为对地理标志林产品品牌竞争力的影响

基于结构方程模型,从企业行为角度(即企业的管理制度、组织协调和营销活动3个方面)对地理标志林产品品牌竞争力的影响因素进行实证研究。结果表明:管理制度、组织协调、营销活动等企业行为与提升地理标志林产品品牌竞争力具有显著正相关关系;就中介作用而言,品牌传播力在组织协调与品牌竞争力之间起完全中介作用,而管理制度、营销活动与品牌竞争力之间起部分中介作用。因此,针对企业层面提出企业应不断完善内部管理制度、重点管理地理标志林产品的质量、充分发挥企业组织的协调功能、及时优化企业林产品市场营销策划、积累地理标志林产品品牌传播力等建议。     

Local Heroes,Regional Champions or Global Mandates? Empirical Evidence on the Dynamics of German MNC Subsidiary Roles in Central Europe

SUMMARY

In this paper we analyze the influence of a subsidiary's external environment, of its task and of its mode of ownership and its mode of market entry on the development of its role for the case of German subsidiaries in Central Europe. We define a subsidiary's role as a three-dimensional construct, consisting of a subsidiary's tasks, its value chain activities and its respective geographical scope. Drawing on a sample of 99 subsidiaries from the Czech Republic, Hungary, and Poland, we find that a subsidiary's host country, its tasks and its mode of market entry influence the development of its role. We find no evidence for the influence of subsidiary's mode of ownership. Especially, “geographical market proximity seeking”-subsidiaries seem to follow a different path of development than subsidiaries where this task is of minor importance as they tend to perform a smaller number of value chain activities and tend to expand these value chain activities with regard to their geographical scope more incrementally.     

医用非晶硒X射线探测器的发展趋势

本文介绍了非晶硒x射线探测器的原理及其在医学成像上的应用，非晶硒材料相对于x射线荧光材料的优势成就了其在x射线探测器中的发展，如具有较高的空间分别率，小的暗电流等。对比了它和针枉状碘化铯x射线探测器的性质及MTF值，指出目前非晶硒在分辨率要求较高的场合，特别是乳腺x射线成像系统中的不可替代性。但是，新近发展的新型碘化铯x射线探测器克服了针柱状碘化铯低分辨的缺点，得到了较高的MTF值，和非晶硒相差无几甚至可超过它，如能继续解决其成像面积问题，该类型的探测器有望在乳腺x射线成像系统中取代非晶硒探测器。     

从社交网络到地理网络——基于南京市高校新浪微博用户的分析

面对网络时代下人类信息传递和社交方式的革命性突破,文章以南京市高校师生的新浪微博用户作为抽样源群体,但在研究思路上又不局限于该师生样本,而是以各样本为原点来分别串联、圈定和分析其跨区域的网络社交关系;继而以"社交网络+地理网络"作为贯穿性主题词和关键指标,按"总体把握"和"师生比较"两个层面展开高校的网络社交特征与时空规律探讨,进而通过"社交关系+社交频率"组合形成的网络关联度对其地理网络进行分析,并与"南京总体微博用户"的地理网络特征和规律的相关研究成果(同样以南京市为基点)进行比较,得出高校社交网络在空间规模上聚集度高、等级差异明显,在关联强度上局限性大、不均衡性强等差异性特征,并剖析得出高校社交网络机制形成的地域植根性、社会经济发展差异性,以及高校群体特有的教育资源(学术前沿)空间分布、群体自身特殊性等动因。     

Does ‘New Regionalism Theory’ Explain the Complementary Role of Foreign Direct Investment and Trade Activity in the Central and Eastern European Region? The Case of Bulgaria

In this paper we attempt to contribute to the ongoing debate about new and old regionalism. First, we focus on the presentation of regional initiatives in the Central & East European (CEE) region and on specific motives behind Foreign Direct Investment (FDI) and trade expansion in CEE countries. Then, through empirical research and the analysis of regional initiatives we found that FDI and trade are complementary to each other, while FDI is a characteristic of new regionalism signifying deeper integration. On the other hand, geographical proximity still plays an important role in trade and investment suggesting that elements from both old and new regionalism are apparent in the CEE region. Only a small number of advanced countries participate in a few regional initiatives. However, membership in regional initiatives - if isolated - does not directly and/or simultaneously imply deep integration (new regionalism).     

Does Accessibility to Higher Education Matter? Choice Behaviour of High School Graduates in the Netherlands

Abstract

This paper identifies pivotal factors behind individual decision making in the transition from high school to post-secondary education in the Netherlands. We apply a multinomial logit framework to individual data and accommodate two types of effects that have not received much attention in the literature. First, we analyse the impact of geographical accessibility of the higher education system. Second, we allow the individual observations to be correlated within schools, in effect accounting for localized social interactions. Our results confirm the paramount influence of the student's track record and talent. The results, however, also show that geographical proximity significantly increases the probability of high school leavers continuing their education at a university or professional college.

有为政府与有效市场：基于基础设施建设对审计市场发展影响的视角

基于新结构经济学理论,以2001—2019年中国A股上市公司为具体研究对象,探讨了基础设施建设对审计市场结构和审计质量的影响。研究发现,基础设施的不断完善削弱了地理距离因素对会计师事务所选择的影响,改善了中国早期审计市场低集中度的特征。与之相对应,事务所与审计客户之间的空间距离逐年增大,事务所的客户覆盖城市(省份)数量逐年增多。基础设施建设的外溢效应还表现在能够显著提高审计质量,改善资本市场信息环境。作为对审计质量提高的应对,上市公司采取了更加隐蔽的盈余管理方式。
