战略性新兴产业上市公司动态创新效率测度及其影响因素研究——基于两阶段DSBM模型与Tobit模型

以873家战略性新兴产业上市公司为研究对象,采用产出导向的DSBM模型测算两阶段整体和不同细分产业的动态创新效率。基于微观企业层面,分别以营业收入增长额、营业收入、营业收入增长率作为技术成果转化阶段的创新产出指标,测算并比较对应的创新效率。结果表明,以营业收入增长额作为创新产出更加符合实际情况,不同细分产业的创新效率存在异质性。进一步运用Tobit模型分析影响企业创新效率的因素发现,在技术研发阶段,企业规模、资产收益率、研发强度、劳动者素质、企业性质对创新效率具有正向影响,研发人员、研发资金、企业年龄、政府补贴对创新效率存在负向影响;在成果转化阶段,发明专利授权数、企业规模、资产收益率、研发强度、劳动者素质对创新效率具有正向影响,员工总数、研发支出、企业年龄、政府补贴、企业类型对创新效率存在负向影响。在创新驱动发展战略实施背景下,结论可为测度战略性新兴产业上市公司动态创新效率提供指导,为提高战略性新兴产业上市公司创新效率提供决策参考。     

要素市场扭曲抑制了绿色创新效率提升吗——高技术产业集聚的调节效应

中共十九大报告指出,要素市场化配置是经济体制改革的重点。利用2003—2019年中国省际面板数据,采用面板固定效应模型和门槛回归方法,实证研究要素市场扭曲、绿色创新效率与高技术产业集聚之间的关系。结果表明,要素市场扭曲会阻碍绿色创新效率提升,高技术产业集聚能够显著促进绿色创新效率提升,并削弱要素市场扭曲对绿色创新效率提升的抑制作用。门槛效应表明,在高技术产业集聚程度较高的情况下,要素市场扭曲对绿色创新效率的抑制作用会被扭转。以上结果均表现出显著的区域异质性。     

企业开放式创新生态系统种群共生关系与演化机理研究

创新生态系统已成为学术界研究热点。已有文献主要聚焦创新生态或开放式创新,将两者结合探讨其演化机理的研究较少。基于国内外开放式创新相关研究,结合种群生态学理论,构建开放式创新生态系统演化模型,并运用MATLAB仿真对企业开放式创新生态系统的演化规律进行深入挖掘。结果表明：企业开放式创新生态系统演化过程包括初创期、成长期和成熟期3个阶段,且演化的4个序参量呈现如下态势：生态网络规模在3个阶段呈现逐步上升趋势,在成熟期达到最大值;生态网络密度在3个阶段呈现缓慢增长的S型趋势;生态网络平均聚类系数在初创期和成熟期增长缓慢,在成长期增长迅速;核心企业在3个阶段均占据优势生态位,并在成熟期达到最高位。     

中国式分权、转移支付与居民收入不平等

本文首先采用基尼系数对我国城乡、城镇和农村居民收入不平等程度进行重新测度,然后以政府转移支付为门限变量建立面板门限回归模型,对财政收支分权与居民收入不平等之间关系进行实证检验,结果发现:一是财政收入分权与收入不平等显著负相关,财政支出分权与收入不平等显著正相关;二是财政收支分权对不同类型收入不平等的作用效果存在较大差异.其中,无论是财政收入分权抑或支出分权对收入不平等的政策效应大小依次是城镇居民＞农村居民＞总体居民;三是政府转移支付在不同区制对居民收入不平等的影响呈现显著地非线性特征.即从相对较低的第一区制跨入较高的第二区制时,转移支付对居民收入不平等的影响由负转变为正.本文以上研究结论不仅对于全面构建央地新型政府间财政关系,还可以为促进公平收入分配提供理论依据与决策参考.     

Understanding the intention to use mobile shopping applications and its influence on price sensitivity

This study employs an extended technology acceptance model (TAM) and the theory of diffusion of innovations (DOI) to understand the intention to use mobile commerce applications for shopping purposes. The variables—perceived enjoyment, perceived risk and personal innovativeness—were added to the original model. The price sensitivity criterion was predicted using the variables—perceived risk, personal innovativeness, satisfaction and the intention to use. An online questionnaire was circulated nationwide through email to verified e-commerce users and a sample of 675 respondents was taken for analysis through structural equation modeling approach. Gender, experience and frequency of using mobile shopping applications were used as moderators for all relationships. Findings of this study reveal that personal innovativeness and perceived risk play a major role in deciding the intention to use mobile shopping applications. Users who are highly innovative and with a higher intention to use mobile shopping applications are less sensitive to price. Various managerial implications including applications to differential pricing, improving adoption pace and segmenting consumers to design marketing strategies are discussed.     

Climate Change,Crop Selection and Agricultural Revenue in Ghana: A Structural Ricardian Analysis

We apply a Structural Ricardian Model (SRM) to farm‐level data from Ghana for seven principal food crops in order to model the factors which influence farmers' decisions about which food crops to grow and the revenue conditional on these choices. Our application of the SRM incorporates a flexible functional form to allow for the possibility that the effects of temperature and rainfall may not be linearly separable. We use this model as a basis for simulations of the effects of climate change. These simulations suggest that extreme climate change will lead to a significant reduction in the average net revenue per hectare from maize, which accounts for over half of current food production. Across a range of climate change scenarios, there is also substantial substitution of maize for heat‐tolerant millet, and a reduction in the cultivation of other crops. Under most of the climate change scenarios that we consider, these results imply a substantial reduction in the aggregate value of agricultural production, since millet is the lowest‐value crop.     

产权稳定性对农户农田基本建设投资行为的影响

研究目的:从产权稳定性的角度研究其对农户农田基本建设投资行为的影响。研究方法:基于全国8省地块层面的调查数据进行计量经济分析。研究结果:产权稳定性对农户农田基本建设投资行为有显著影响,产权稳定性越低,农户进行农田基本建设投资行为的可能性越小。Logit模型估计结果显示,与没有使用凭证的地块相比,农户在有使用凭证的地块上进行农田基本建设投资的概率将提高2.54个百分点;村级农地调整每增加1次,农户进行农田基本建设投资的概率将下降1.70个百分点。这是因为,地块缺少使用凭证和农地的频繁调整提高了农地政策变化的不可预期性,导致农地产权在法律和事实上变得不稳定,进而抑制农户对农田进行基本建设投资。研究结论:为提高农户农田进行基本建设投资的积极性,应确保农地确权政策落实,深化农地产权制度改革,提高农民产权主观认知,全面增强农地产权稳定性。     

Total quality management, market orientation and hotel performance: The moderating effects of external environmental factors

With the market competition of hotel industry being heated, it is critical that hotels have a breadth of resource and more flexible forms to meet the needs of a changing marketplace. In the past, the relation of total quality management (TQM), market orientation, and performance are equivocal. These mixed results may be due to some factors or not to include the environmental factors. This study adopts the Input-Processing-Output (IPO) concept model to construct all variables research model. The research surveyed samples of 588 and used Structural Equation Model and discriminate analysis for analysis and testing. The results show that TQM positively affects hotel performance. Market orientation positively affects hotel performance. Market orientation has the mediating effect between TQM and hotel performance. External environment factors truly play a moderator between TQM, market orientation and hotel performance, especially when external environment factors greater changes are going to help to build relationship with customer, to enhance hotel performance and further to gain chance of hotel's survival.     

The effect of environmentally friendly perceptions on festival visitors’ decision-making process using an extended model of goal-directed behavior

This study examined the effect of environmentally friendly perceptions on the behavioral intention of visitors at the Boryeong Mud Festival in South Korea. The results of the on-site survey (N = 400) reveal that three environmentally friendly perceptions formed positive and significant causal relationships with the constructs in the extended model of goal-directed behavior (EMGB). Attitude, subjective norm, and positive anticipated emotion affected desire, which, in turn, influenced the behavioral intention. Three elements, volitional, non-volitional, and emotional aspects, were proven to be crucial in comprehending the perceptions and behaviors of the nature-based festival attendees. The findings of this study will shed light on a better understanding of the decision-making processes of festival visitors when environmental issues are incorporated.
