构建一体化国家战略体系和能力是新时代实施军民融合战略的重要目标,军民科技协同创新则是实现该目标的必然选择。基于扎根理论建立军民科技协同创新影响因素体系,通过分析影响因素间的交互关系构建系统动力学模型。根据模型对案例进行仿真分析,考察单因素作用、多因素协同作用、多因素非协同作用条件下协同创新水平变化情况。从军民科技协同创新内涵、结构、功能实现3个层面揭示要素融合机制。据此,为国家军民深度融合提供相应政策建议。  相似文献

基于经验学习理论,探究创业失败经验如何通过创业失败学习影响创业者连续创业意愿,以及市场动荡性的调节作用。对176位有失败经历的创业者进行问卷调查,结果表明:创业失败经验对创业失败学习和连续创业意愿均有显著正向影响;创业失败学习在创业失败经验与连续创业意愿关系间起中介作用;市场动荡性负向调节创业失败学习与连续创业意愿的关系,即市场动荡性越高,创业失败学习与连续创业意愿间的关系越弱。研究结论对于拓展创业失败经验与连续创业意愿研究、帮助创业者从失败中复原,以及激励连续创业具有重要理论价值和实践意义。  相似文献

[目的]通过深入研究黄土丘陵区贫困人口生计资本对生计活动的影响,为解决农村贫困问题,提升农户生计资本存量、实现区域可持续生计发展提供科学依据。[方法]文章以甘肃省榆中县为例,基于对榆中县农户的调查数据,采用熵值法分析了东北部山区、中部川区和西南部山区贫困人口的生计资本状况和生计活动方式,并对其生计活动进行评价。[结果]从农户的生计资本组合来看,榆中县整体自然资本和人力资本相对物质资本、金融资本、社会资本3类资本较为富裕,尤其在西南部山区和东北部山区3类资本缺乏型农户比例较高。中部川区各乡镇人口的总体生计资本状况较好,总指数最高,而西南部山区次之、东北部山区最低,两者生计资本状况总体匮乏。农户的生计活动主要以种植、养殖和外出打工为主,生计活动多样性程度偏低; 中部川区人口的生计活动多样性指数最高,西南部山区次之、东北部山区最低,且整体受教育程度偏低,加之物质资本、金融资本、社会资本缺乏进一步限制了当地农户的生计多样性。[结论](1)针对不同生计资本水平和生计活动多样性程度偏低的贫困地区,需要进一步发挥民族文化产业扶贫优势,开启地域产业扶贫新模式,打造地域无公害特色农业产业品牌,提高农户物质资本边际贡献; (2)发展小额信贷金融服务,改善农户金融资本存量,预防村际农户金融资本二元极化; (3)实施免费教育培训技能学习,打造教育培训脱贫示范村,提高人力资本存量,缓解贫困人口生计压力等提高经济发展水平的扶贫政策措施。  相似文献

[目的]通过引入社会互动变量改进目标导向行为理论框架,探讨生猪规模养殖户对环保饲料的支付意愿及其影响因素,为完善畜禽养殖污染防治政策提供参考借鉴。[方法]以湖北省生猪规模养殖户为研究对象,应用Heckman两阶段模型,研究规模养殖户对环保饲料的支付意愿。[结果]大多数规模养殖户(8134%)愿意采用环保饲料,且平均意愿支付水平为每头生猪饲料成本的669%(4680元/头)。社会互动中的干群互动、同行互动均能显著提升规模养殖户对环保饲料的支付意愿,但同时同行互动不利于其意愿支付水平的提升。进一步的异质性分析表明,在环保饲料支付意愿决策上,社会互动较少的规模养殖户更容易受到制度规范的约束,而社会互动较多的规模养殖户则更易受到感知养殖热情的影响。[结论]政府部门应加大生态环保宣传力度,并借助多种方式推动规模养殖户进行社会互动; 同时可依据社会互动程度的不同,分别制定相应措施以促进规模养殖户对环保饲料支付意愿的提升。  相似文献

This study is among the first to investigate the impact of message, source, and receiver characteristics on user attitudes toward Yelp reviews, with the subsequent impact of these attitudinal evaluations on review persuasiveness. Specifically, it examines the roles of review valence (positive/negative) and sidedness (one-sided/two-sided), as well as perceived similarity with the reviewer, on user perceptions of helpfulness, trustworthiness, and credibility of the review. The study also tests moderating effects of perceived source similarity and user regulatory focus on the relationships among message characteristics, attitudinal variables, and purchase intentions. Our results disconfirm the negativity bias reported in previous studies and indicate that positive reviews are perceived as more trustworthy, credible, and helpful than negative or two-sided reviews. Review helpfulness and credibility, in turn, positively impacts its persuasiveness, with regulatory focus playing a complex nuanced role in the persuasiveness – behavioral intentions relationship. Based on the findings, future research avenues and managerial implications are proposed.  相似文献

This paper examines the selective trading of available-for-sale (AFS) securities by U.S. banks after the implementation of fair value accounting under Statement of Financial Accounting Standards No. 115, Accounting Standards Codification Topic 320. Our findings suggest firms still engage in earnings management through selective selling of AFS securities despite the mandatory disclosure of unrealized security holding gains and losses in their financial statements. Such activities do not appear to be driven by the lack of reliability of the fair value measure. Instead, the degree of earnings management varies significantly with the reporting format of unrealized AFS security holding gains and losses. We find evidence of earnings management among banks that choose to report unrealized holding gains and losses in the statement of shareholders’ equity. By contrast, we find no such evidence among banks disclosing unrealized holding gains and losses in the income statement.  相似文献

In the face of state-led land grabs, enterprising Chinese peasants have started a revolution in the ambiguous and insecure rural tenure system by developing an extralegal property system known as the small property right (SPR). Using the SPR, peasants are able to capitalize on their property through the sale of houses built on collectively owned land. Little is known, however, about the specific process behind the development of the SPR by the peasants, or how this extralegal property system functions in terms of securing the use and transfer of property without the backing of law. This article aims to clarify the situation through the lenses of the Endogenous Nature of Institutions and Relational Contract Theory, aiming to understand the socially constructed, endogenous and relational nature of the property rights that make SPR functional. Based on an ethnographic investigation of Beijing's largest SPR housing settlement, we show how enterprising peasants develop long-term relational contracts with urban households for the provision of housing services, secured on the basis of the common interests and symbiosis of the two parties and a reputation system that serves to deter defaults. The discretionary treatment of SPR housing by local states serves as a further motivation for the village and the informal homeowners to preserve a stable property arrangement, with such a specific institutional setting being an exemplar of China's pragmatic state entrepreneurialism.  相似文献

Abstract

As an important component of organizational human resource slack (HR slack), the slack of research-and-development (R&D) professionals has been studied by several authors. However, it remains unclear whether and how this small component of general HR slack, i.e. the slack of research-and-development professionals (RHR slack), may affect overall firm performance in an emerging economy without much R&D tradition or pro-R&D institutions. Based on two organizational theories, i.e. institutional theory and the resource-based view of the firm (RBV), we propose competing hypotheses on the relationship between RHR slack and firms’ accounting performance. We also examine whether the relationship between RHR slack and firm performance should be linear or curvilinear. Finally, we also test the relationship between RHR slack and other dimensions of firm performance. Several interesting findings have been obtained. For instance, neither the perspective based on institutional theory nor that based on RBV can fully predict all types of RHR slack-performance relationships, be these relationships linear or curvilinear.  相似文献
