我国行政审批制度改革的力场分析与突破策略

行政审批是政府对市场和社会资源进行配置的前置性管理手段。为了与社会主义市场经济体制相匹配,我国在行政审批改革中设立了减少审批项目、规范审批行为、实现制度创新和推进依法行政的改革目标。但根据力场分析理论,在行政审批制度改革过程中由于对相关主体利益的重新分配造成改革力场中存在驱动力和制约力。通过研究改革中决策者、执行者、受规制者和消费者的利益取向,可以获知驱动力和制约力的强弱,并推算出制度变迁的方向。为了使行政审批制度改革能够顺利推行,还需进一步分析制约力存在的方式并寻求相应的突破策略。     

农业创业情境下商业模式设计的影响机制研究——基于模糊集定性比较分析

农业创业者如何通过整合与管理资源与能力，设计新颖型商业模式创造更多价值，是实现乡村振兴战略的关键措施。文章基于资源编排、商业模式理论，以央视《致富经》栏目40个案例为样本，运用模糊集定性比较分析（fsQCA）方法，剖析资源编排、机会能力、创业学习所构成的前因变量组态对农业创业活动中商业模式设计的影响机制。研究发现，资源编排在农业创业活动中发挥不可或缺的关键作用；相较于资源结构化和资源捆绑，资源利用在新颖型商业模式设计中的作用更为突出；机会能力须与资源编排共同作用，方可实现新颖型商业模式设计；在资源编排作用缺乏时，创业学习的发挥有助于新颖型商业模式设计的形成。研究成果诠释了农业创业情境下资源编排、机会能力与创业学习对商业模式设计的影响机制，为开展农业创业活动提供指导。     

玉林市存贷比运行特征、存在问题及对策建议——基于桂东四市比较

存贷款比例是银行业金融机构经营管理的重要指标之一,存贷比例过低不利于地方经济的发展。广西玉林市自2000年以来,存贷差逐年扩大,存贷比长期在低位徘徊,2013年存贷比在广西全区排最后一名。本文通过桂东四市（玉林市、梧州市、贺州市、贵港市）经济金融主要指标对比,分析玉林市银行业金融机构存贷比运行特征,揭示造成玉林市低存贷比的原因,提出提高存贷比的相关措施以及科学合理看待存贷比的建议。     

央行货币政策报告文本信息、宏观经济与股票市场

本文利用金融情感词典和文本分析技术,分析中国人民银行货币政策执行报告的文本情绪、文本相似度和文本可读性等多维文本信息,刻画央行货币政策执行报告的文本特征,探究货币政策报告的文本信息与宏观经济和股票市场的关系。实证研究发现,货币政策报告的文本情绪的改善会引起显著为正的股票市场价格反应,报告文本相似度的增加会引起股票市场波动性的显著降低,报告可读性对公布后股票市场的波动性影响不显著。货币政策报告文本情绪还与诸多宏观经济指标显著相关。进一步研究发现,引起股票市场显著反应的是报告文本情绪中反映货币政策指引的部分,而反映宏观经济历史状态的部分对股票市场的影响不显著。本文从文本大数据分析角度证明了我国央行沟通的有效性,对国内央行沟通相关研究形成了有益补充。

Relationship between city size and firm productivity – A new interpretation using the Chinese experience

This paper contributes to the literature on the relationship between city size and firm productivity by focusing on agglomeration, selection (market competition), and sorting (presence of firms with diverse productivity) effects using Chinese firm-level data for 1998–2013. Contrary to the existing literature, our parametric regression estimates from nearly two million firms show that when the selection effect is controlled, productivity advantage in big cities is reversed. This outcome is explained through a quantile regression showing the existence of left-sided sorting (inefficient firms sort themselves to larger cities) in big cities which is not captured in existing empirical literature. We further find that (1) left-sided sorting is stronger in exporters than non-exporters; (2) is also generated mainly in enterprises with high asset-liability ratios; and (3) selection has a positive effect on firm productivity, suggesting that market competition is key in an explanation of the rapid growth of big cities in China.

目的了解某院药品不良反应(ADR)的发生特点及规律,为临床安全用药提供参考。方法对合肥市第二人民医院2016年至2018年上报的ADR报告进行回顾性分析。结果1864例ADR中,66~89岁患者所占比例最高(768例,占41.20%);女性患者984例,略多于男性(880例);静脉给药引发的ADR最多,占81.33%;发生ADR的药品主要为抗菌药品,其次为抗肿瘤药和中药制剂;ADR主要累及消化系统、皮肤及附件;ADR类型主要为一般ADR,导致严重的ADR主要是抗肿瘤药;ADR转归情况以痊愈和好转为主,两者占94.31%。结论老年患者更易发生ADR;抗菌药、抗肿瘤药等ADR发生率较高;所有剂型中注射剂型ADR发生率最高;消化系统、皮肤及附件损害最为常见。     

研发市场界定的适用困境及应对策略

研发市场是经营者在特定产品和技术竞争中形成的市场范围。由于研发活动的不确定性，反垄断执法机关在界定研发市场时难以准确厘定市场边界，更深层次的原因在于维持竞争与激励研发的关系尚不明晰。研发竞争中的垄断行为难以通过相关市场界定的方式判断其违法性，需要结合具体案情和市场条件，动态分析涉案行为是否损害产品或技术研发竞争。

The effects of tourism on HSR: Spanish empirical evidence derived from a multi-criteria corridor selection methodology

The exorbitant cost of new High-Speed Rail (HSR) lines requires a selection methodology to define which HSR corridors within a network should be built first, and the most suitable evaluation tool appears to be the multi-criteria approach. In any corridor-ranking methodology, and especially in countries with high tourism attractiveness, tourism impacts on HSR should be considered as a variable.In addition to economic geography and destination choice models, the current literature on tourism demand is dominated by econometric models using a single-equation time-series based approach. However little research has been done so far on methodologies to rank HSR corridors taking into account the tourism variable. In 2014, a ranking methodology developed by Todorovich and Hagler was validated using the current Spanish HSR network. Twelve variables were used to create an index to assign scores to the city pairs, but tourism was not included as a variable. The findings showed the consistency of the model for ranking pairs mainly in the top O–D relations; however the tool failed to discriminate clearly between secondary groups of corridors.The aim of this paper is to assess empirically the positive effect of tourism on HSR and to enhance the abovementioned ranking tool with a tourism database. The new methodology is tested by application to 1176 city pairs in Spain, and the results clearly show that the implementation of a tourism variable helps discriminate between secondary groups of corridors and offers a more effective approach for determining the implications of tourism on HSR.
