将“合伙人制”融入“合作制”的一项尝试——基于MGL合作社的案例解读与探讨

当前,合作社异化已成为阻碍合作社进一步发展的痛点,其中"合作制"下社员剩余索取权和控制权的丧失是矛盾核心,因而探求其改进方式对合作社长远发展、实现乡村振兴有重要意义。本文基于效率与公平衡量维度,通过对MGL合作社这一典型案例进行剖析发现,有效的合作社在治理结构和利益分配上具备"合伙人制"特征,并且基本契合不完全契约理论有关能够有效解决契约双方信息不对称以及剩余索取权、控制权被少数社员占有的论述。对此,应充分重视合伙人制在合作社发展中的内在有效性,弱化其是否具有规范的外在形式。     

论人工智能在武装押运行业的应用

武装押运行业是安保行业中重要的细分领域,具有危险性高、准确性高、服务要求高等特点。目前,绝大部分押运安保企业仍然停留在GPS车辆定位、视频监控等基础安防技术的应用上。随着人工智能技术的不断发展,及其在行业应用的不断积累,人工智能势必对武装押运行业的发展产生巨大的影响。本文将对人工智能技术在武装押运行业应用的可行性及意义进行探讨,其中,主要分析了押运路线智能规划、尾箱人脸识别交接、安全驾驶智能识别驾驶员的特征、智能化库房及机器人的应用等方面。     

银行金融机构远程签约法律问题分析及建议

随着信息技术的发展,银行金融机构以远程签约的方式开展各类业务的趋势越来越强烈。银行金融机构作为受到专门监管的金融机构,需要在符合当前监管规则的情况下对远程签约方式进行规范地运用,并关注远程签约方式可能带来的结果验证、信息治理、业务外包以及线上交易文本配套等问题。本文对银行金融机构远程签约可能面临的法律问题进行分析,并针对这些问题提出若干建议。     

投桃何以报李:企业内外部社会责任对管家行为的影响机制研究

当员工感知到企业的善行,即企业善待员工或是积极履行对外部利益相关者的责任,是否会激发员工"舍己为公"的行为倾向,使其为了保护组织长远利益而牺牲个人短期利益呢?本研究依据社会交换和社会认同理论,通过524份有效样本进行实证分析,探讨员工感知的企业社会责任对"舍己为公"的管家行为的作用机制。结果表明,员工感知的内部和外部企业社会责任均正向影响员工的管家行为。责任知觉和道德认同分别在员工感知的内部企业社会责任与管家行为、员工感知的外部企业社会责任与管家行为间起中介作用,且责任知觉和道德认同的中介作用没有显著差异。

How entrepreneurs recognise entrepreneurial opportunity and its gaps: a cognitive theory perspective

ABSTRACT

Previous studies have verified the relationship between entrepreneurial opportunity recognition and performance. However, the influences of a perceived gap between entrepreneurial opportunities before and after launching a new venture have been neglected. This study applied the partial least square method to analyse the entrepreneurial behaviours and performance of 214 Taiwanese new ventures, and adapted the bootstrap re-sampling method for estimating the variables. The empirical results showed that entrepreneurial resource and entrepreneurial alertness significantly influence the perceived opportunity, while the entrepreneurial resource significantly affects the actual opportunity. The results further demonstrated that both the perceived opportunity and actual opportunity considerably influence new venture performance. This study offered a research framework to better understand the cognition path of entrepreneurial opportunity, and suggested the factors affecting the recognition of perceived opportunity by longitudinal method can be further evaluated. To improve performance, entrepreneurs should enrich entrepreneurial resources and allocate them appropriately, and heighten and maintain their alertness to reduce the perceived gap arising from recognising entrepreneurial opportunities.     

Search within or beyond the industrial cluster? The effect of perceived competition and knowledge base tacitness on strategic location choices of external knowledge search

ABSTRACT

From a knowledge-based perspective, this paper highlights the need for a framework linking perceived competition of the industry and firms’ strategic location choices of external knowledge search and examines whether the perceived competition increases the propensity of cluster firms to search more widely from extra-cluster knowledge sources than intra-cluster knowledge sources. Furthermore, we emphasise that cluster firms with varying degrees of tacitness in their knowledge base might respond to such competition differently when conducting external knowledge search activities. Using a sample of 310 cluster firms in the Zhejiang Province of China, we find that the cluster firm would increase the propensity for more geographic boundary-spanning search relative to local search while under the pressure of competition. Moreover, the positive relationship between perceived competition and the propensity towards geographic knowledge search is weaker when the tacitness of the cluster firm’s knowledge base is higher. The findings contribute to the understanding of the relationship between competition and the choice of location strategies in external knowledge search.     

Household responsibility system and China's agricultural Growth revisited: Addressing endogenous institutional change

The rise of the Household Responsibility System has been widely viewed as a significant contribution to China's agricultural growth. However, this empirical conclusion is rested upon a convenient but doubtful presumption that the process of institutional change, also known as decollectivization, is exogenous. We contribute to this literature by explicitly recognizing the endogeneity of institutional changes, and exploit exogenous variations in lagged weather shocks and initial fixed assets for consistent estimation. With improved data on irrigation, mechanization, weather and institutional changes in a provincial panel data during 1970–1987, the results of panel instrumental estimations reveal that the Household Responsibility System had a significantly positive effect on China's agricultural growth, which was larger than indicated by OLS estimates that suffer from adverse selection and attenuation biases.
