Revisiting the cooperation–competition paradox: A configurational approach to short- and long-term coopetition performance in business networks

Cooperation and competition are often viewed as incompatible, antagonistic forces, thus are operationalized as two extremes on a continuum. However, they can coexist and even enable each other, thus may be operationalized as orthogonal constructs. We address this contradictory phenomenon by developing a more granular view of the cooperation–competition paradox. Building on interdisciplinary research, we develop a three-dimensional model of relational space (fairness–opportunism, sharing–control, and engagement–rivalry), providing a novel tool with which to investigate the paradoxical interplay between cooperation and competition through eight operationalizable configurations. Using fuzzy-set qualitative comparative analysis (fsQCA), we test our model by assessing how different configurations of interfirm relationships influence the short- and long-term success of a sample of 217 firms. Our findings show that only two of the eight possible relational configurations are associated with firm success, one in both the long and short term, and the other in the short term only.     

金融结构对产业结构影响的时变特征研究——基于SUR和TVPSS模型的实证检验

金融结构与产业结构的关系一直是学术界的研究热点.文章利用中国1998—2017年的年度数据,构建似不相关回归模型从金融结构规模、效率及深化的角度分析金融结构对产业结构合理化和高级化的影响,建立时变参数状态空间模型描绘了金融结构对产业结构合理化和高级化的动态冲击.实证分析结果表明:金融结构规模提高产业结构合理化水平,促进了产业结构高级化;金融结构效率提高产业结构合理化水平,抑制了产业结构高级化;金融结构深化降低产业结构合理化水平,促进了产业结构高级化.金融结构规模、金融结构效率及金融结构深化对产业结构合理化和高级化的冲击均呈现出时变特征;金融结构对产业结构合理化的影响滞后于其对产业结构高级化的影响.金融结构对产业结构的冲击波幅呈现出前期波动大、后期较为平缓的状态,部分金融结构变量对产业结构的动态冲击呈现出"长尾"现象.当前的中国金融结构已经不适合当前的产业结构,需调整金融结构,以提升产业结构合理化水平和高级化水平.     

德国保护地体系评述与借鉴

德国保护地体系是沿袭历史逐步形成的。首先论述了德国保护地体系的法律基础,并对11类德国保护地的定义、现状和管理事权进行了解释。继而对德国保护地体系进行归纳总结:各类保护地由《联邦自然保护法》统筹、分级管理,以自然保护为核心目标;各类保护地地界交织现象广泛存在,从而实现更广泛的连接;关注文化与自然的融合,强调文化景观管理;各类保护地倾向不同功能,平衡保护与利用并合理发展可持续旅游;法治巩固本土特色的保护地。最后对我国的保护地体系进行相关思考:法定保护地须纳入国土空间规划;包容自然与文化景观的保护地可与"自然公园"相得益彰;对保护地的利用及管理需要通过统一规划实现。     

地理空间视域下斯达尔夫人与刘师培南北文学论比较研究

尽管斯达尔夫人和刘师培分处东西方历史发展的不同时期,但是斯达尔夫人的欧洲南北文学论与刘师培的中国古代南北文学不同论具有重要的比较诗学研究价值。斯达尔夫人的欧洲南北文学论和刘师培的中国古代南北文学不同论基于各自不同的理论背景和历史背景都引入了地理空间视域,其比较诗学研究的理论内涵主要包括三个方面：一是地理空间视域引入的不同理论背景、历史背景、理论内涵;二是地理空间视域下语言维度研究进路的异同;三是吊诡的倒转性：北方浪漫主义、南方古典主义与北方古典现实主义精神、南方浪漫主义精神。     

湖南民族地区生态文明建设的国土空间规划应对

加强生态文明建设是破解湖南民族地区发展滞后、提高其生态环境系统治理和保护水平的关键举措。结合湖南民族地区生态文明建设的总体情况,分析了湖南民族地区的人口分布、自然地理、经济发展和民俗文化等特征,提出了基于“两山”理念的湖南民族地区国土空间规划重点,即：加强空间联动,优化民族地区空间布局;创新扶贫方式,构建民族地区特色产业体系;提高资源利用效率,加大民族地区生态补偿力度。同时,提出了湖南民族地区国土空间规划路径：加强“三生空间”管控,转变依靠资源型致富的传统思维;创新生态治理方式,构建产业体系;注重生态系统整体保护,有效提升空间治理水平。     

The reinvention of the Promised Land: utopian space and time in Soviet Jewish exodus literature

The Jewish underground movement in the Soviet Union in the second half of the 1960s produced literature that became a part of the counterculture of Soviet dissent. For the first time in decades, Russian Jews identified, to a significant degree, as people of the galut (Jewish Diaspora). The battle for the return to Israel and the new Jewish renaissance in the intellectual sphere of the unofficial led to the emergence of new topographical concepts, which were inspired primarily by the Jewish cultural tradition. In fact, the exodus texts written in the 1960s–1980s represented a new, late Soviet shaping of Zionist prose. They relate to the symbol of the Promised Land as a fundamental projection of aspirations. Late Soviet Zionist texts share the traditional Jewish vision of Israel as an imagined topos of the original homeland that is both retrospective (with reference to the biblical promise of the land and the seizure of Canaan) and prospective (return and redemption). The Exodus story contained in Sefer Shemot becomes a leading poetic, philosophical and at times religiously charged metaphor of liberation and reunification. The re-strengthened collective memory of tradition required biblical symbols to be imbued with new semiotic power.

This paper will show that the historical dimension of the events dealt with in the literature often has strong mystical and mythological traits and displays messianic-apocalyptic hopes of salvation. However, alternative literary space and time models represented in the aliyah literature hereby betray their rootedness in the teleology of the communist regime. The powerful Israel utopia reflects both the eschatological time of the Soviet empire and its phantasms of paradise on earth. Late Soviet Zionism and totalitarian discourse are shown to be two space-time utopias.     

Maximizing Probability Bounds Under Moment-Matching Restrictions

The problem of characterizing a distribution by its moments dates to work by Chebyshev in the mid-nineteenth century. There are clear (and close) connections with characteristic functions, moment spaces, quadrature, and other very classical mathematical pursuits. Lindsay and Basak posed the specific question of how far from normality could a distribution be if it matches k normal moments. They provided a bound on the maximal difference in cdfs, and implied that these bounds were attained. It will be shown here that in fact the bound is not attained if the number of even moments matched is odd. An explicit solution is developed as a symmetric distribution with a finite number of mass points when the number of even moments matched is even, and this bound for the even case is shown to hold as an explicit limit for the subsequent odd case. As Lindsay noted, the discrepancies can be sizable even for a moderate number of matched moments. Some comments on implications are proffered.
