数字普惠金融的创业效应与收入不平等:数字鸿沟还是数字红利？

数字普惠金融与实体经济之间的关系受到学界广泛关注,但其究竟是普惠的数字红利还是金融领域的数字鸿沟,这是数字普惠金融快速发展中亟需回答的重要理论与现实问题。文章通过匹配宏观统计数据和微观调查数据,实证研究了数字普惠金融的发展对收入不平等的影响,并从创业效应这一渠道进行了机制分析。研究发现：数字普惠金融的发展总体上改善了收入不平等状况,而数字普惠金融的创业效应是影响收入不平等的重要渠道之一。进一步的中介效应分析表明,数字普惠金融的创业效应对收入不平等的影响存在异质性：数字普惠金融通过促进生存型创业从而改善了收入不平等,而数字普惠金融对机会型创业的促进却在一定程度上扩大了收入不平等。文章的研究结论对于理解数字普惠金融发展的正外部性以及如何缓解收入不平等提供了新的视角。     

Making the next move: When does the newness of experience matter in overseas sequential entries of multinational companies?

Traditional internationalization models suggest multinational companies (MNCs) can exploit their accumulative experience to facilitate their sequential entries. However, experience may depreciate over time. Thus, obtaining benefits from prior experience for MNCs is based on two critical premises, i.e., interpreting and applying experience correctly. We argue that there is a need to study the newness dimension of experiential learning. In doing so, we aim to explore to what extent the newness of experience matters in overseas sequential entries for MNCs. Moreover, we expect that the benefits from recent experience in guiding sequential entries are contingent on the extent of context similarity between the most recent entry location and sequential entry location and the outcome expectancy of focal entry. With a sample of 112 Chinese listed firms and 410 observations during the period of 2000–2012, we find that else being equal, the newness of experience of MNCs is positively associated with sequential entry and such a relationship is positively moderated both by context similarity in institutional environment and the outcome expectancy of the focal entry. We also compare the effects of the newness of different types of experience and find that the newness of the most recent experience has a larger influence on sequential entry than location-specific experience and general experience.     

高技术服务业与资源型产业融合对资源型企业两阶段创新效率的影响

基于新技术与新知识的高技术服务业跨界融合是传统企业实现创新资源优化配置、创新研发和商业转化的重要因素。因此，运用熵指数测度全国各省区高技术服务业与资源型产业融合水平，并利用2014—2017年资源型上市公司面板数据检验两大产业融合对资源型企业两阶段创新效率的影响，同时探讨企业吸收能力的调节作用。结果表明：现阶段高技术服务业和资源型产业融合程度不高，但发展态势良好，处于从失调走向协调的转变期；产业融合对资源型企业创新研发效率短期无显著影响，长期存在抑制作用，资源型企业技术能力刚性导致对新技术的排斥，且较大的产业间认知差距削弱了产业间良性互动带来的技术扩散效应；产业融合对创新转化效率呈先抑制、后促进效应，就长期而言，产业融合具有良好的创新转化推动力；资源型企业吸收能力分别在产业融合与滞后一期创新研发效率及滞后三期创新转化效率的关系中起正向、负向调节作用，表明资源型企业吸收能力构建尚不全面。     

转译社会学视野中的传统习俗与环境治理--以闽南春节“禁炮”行动为例

闽南春节燃放鞭炮的传统习俗由来已久,近年来城市社区面临环境污染问题,为解决突出的环境问题,在环境治理的时代背景下,政府出台了禁止在市区燃放鞭炮的规定。而关于"禁炮"的行动,被政府随之开展,也引发了传承传统文化与保护生态环境的矛盾。转译社会学是科学社会学的重要理论,以该视角考察闽南春节"禁炮"的社区协商与环境治理机制,分析作为"禁炮"行动发起人的政府所采取的四个转译策略,探寻相关行动者为有效解决这一矛盾的路径,最终形成一个异质型行动者网络。

The effects of haze pollution on stock performances: evidence from China

Haze pollution has become the most important environmental issue in China in recent years. Using the data of PM_2.5 concentration and stocks of listed companies located in Beijing between 2010 and 2014, this article investigates the effects of haze pollution on stock performances. Empirical results indicate that haze pollution has significant negative effects on stock returns and significant positive effects on stock volatilities, through the channel of investors’ mood. Furthermore, the effects of haze pollution on stock returns emerge gradually and the effects of haze pollution on stock volatilities weaken gradually over time during a trading day.     

多孔结构建筑材料力学性能的有限元分析

多孔材料是一种新兴的材料,制备较易,成本较低。相对于一般连续介质材料而言,多孔材料具有比强度高、比表面积高、相对密度低、重量轻、隔音、隔热等优点。它最大的特点是具有排列规则、大小可调的孔道结构,在建筑材料中也有很多的应用。因此,对非均匀孔洞与均匀孔洞建筑材料力学性能的研究是很重要的课题。论文通过建立非均匀孔洞和均匀孔洞的有限元模型,对比分析两种模型的受力性能,更好地进行多孔建筑材料的推广和使用。     

企业家社会责任行为方式创新对其形象评价的影响机制研究

运用扎根理论探究了企业家创新性社会责任行为的特征及作用机制。基于扎根理论，就企业家微公益行为对其形象评价的影响机制进行了探索性研究。通过深度访谈与二手数据的扎根分析，提出了企业家微公益行为对其形象评价影响的理论框架：企业家微公益行为具有权威性、互动性与多样性，会通过情感和认知两大层面来获取消费者认同感，并影响消费者对企业家微公益行为动机的感知，进而影响其形象评价。该研究是对企业家社会责任理论的有益拓展，同时为希望通过社交网络进行公益活动的企业家提供了实践参考。     

Opportunity recognition and SME performance: the mediating effect of business model innovation

Opportunity recognition is vital for small and medium-sized enterprises (SMEs), but SMEs face challenges in capturing recognized opportunities. Given that opportunity recognition does not automatically lead to higher SME performance and that SMEs need to take appropriate actions to exploit recognized opportunities to achieve better performance, it is imperative to explore the mediators that enable SMEs to translate opportunity recognition into higher performance. This study proposes that business model innovation may be a key conduit through which opportunity recognition affects SME performance. Based on a dataset of 155 SMEs, we find that the positive relationship between opportunity recognition and SME performance is mediated by business model innovation. These findings not only aid SMEs in accomplishing the performance effect of opportunity recognition, but also provide some insights into the implications of business model innovation.     

唐宋里坊制演变及其对当前的启示——国家与社会关系的视角

唐宋之交商品经济的蓬勃发展及其引发的一系列制度变革导致国家和社会关系从"国家凌驾于社会之上"向"国家与社会互动"变迁。里坊既是国家权力在城市的末梢,也是城市居民的基本生活场域,是联结国家和社会关系的纽带。国家和社会关系的重构也导致里坊制的演变,坊墙逐步被废除,里坊的社会控制功能也大大弱化。里坊制的演变又推动了商品经济发展、城市文化繁荣、社会组织发展、市民的空间流动与身份流动,进而进一步促进国家与社会互动。这与我国从计划经济到市场经济转型过程中单位制的演变具有诸多相似之处,并给我们带来以下三点启示:(1)从单位制到街区制对我国当前国家和社会关系调整具有积极作用;(2)单位制的消解是一个长期的过程,有可能出现阶段性反复;(3)围墙是单位制的重要组成部分,其存废预示着单位制的兴衰。
