家族企业究竟是促进创新还是阻碍创新?——争论与整合

在学术界一直存在一个争论:家族涉入是促进了企业创新还是阻碍了企业创新?厘清上述争论的产生原因和影响因素,有助于解释家族企业创新研究的争论和拓展家族企业创新研究的视野。本文对近年来相关文献进行了系统地梳理,归纳出家族企业创新三个领域的研究成果:家族企业创新投入、家族企业创新产出、家族企业创新的影响因素(内部家族因素和外部环境因素),分析家族企业创新争论产生的原因,并针对现有研究存在的不足,对未来的研究提出展望。本文提出通过构建权变理论整合家族企业创新争论的研究方向,有助于丰富家族企业创新的理论研究。     

基于模糊评价法的小微文化企业孵化集聚环境研究——以上海为例

研究构建了10个因子指标、若干解释指标构成的评价体系。利用模糊评价法,以上海百余家小微文化企业为对象,考察研究企业孵化集聚环境。结果显示,宏观层面,上海的优势体现在规范高效的政府管理、国家战略支撑下的有利政策等方面,市场、人才、金融环境等原本应有的城市优势,却可能受到国有、外资企业的挤压,反被放大为小微企业的弱势。微观层面,小微文化企业孵化集聚生态尚未建立。     

A New Approach to Measuring a Multidimensional Productivity Index: An Application for 60 Selected Countries

This study aims to develop a productivity index which takes into account the multidimensional characteristics of productivities. Our multidimensional productivity index (MPI) not only measures individual productivities of economic resources but also evaluate productivity enhancing general capacities of economy. Individual productivity indices such as labor productivity are limited because they do not consider the factors, such as the globalization of economies and the market and institutional variables, that could have profound impacts on productivity. The multidimensional Productivity Index (MPI) is measured for 60 countries including 23 OECD countries and 10 Asian countries. Our methodology employs the concept of technical efficiency that allows us to measure the extent to which institutional and market factors contribute to the economic performance. Our findings indicate that standard productivity measures such as labor productivity may overestimate the overall productivity differences across the economies.     

Attitude toward business environment of auditing,corporate governance and balance between auditing and marketing

The aim of this study was to evaluate the attitude of Iranian auditors toward balance between auditing and marketing with respect to two important components of audit process such as business environment of auditing and corporate governance. The analysis is based on survey data from 257 respondents. To achieve the research aims, we specified four hypotheses based on social theories. The results of this study show that the auditors having positive attitude toward marketing and those who consider it as significant are able, to a large extent, balance spent time for inherent auditing tasks and marketing activities. In addition, the results show that an increase by a unit for the attitude toward business environment results in 0.489 unit increase in attitude toward balance of time spent on marketing and auditing activities, of which 0.396 is direct impact and 0.093 is indirect impact.     

A tool for analysing the interdependence of indoor environmental quality and reported symptoms of the hospitals’ personnel

The working environment and the working conditions can influence the well-being of hospital employees and consequently their performance at work. The present questionnaire-based study (737 valid questionnaires) developed and evaluated a quantitative structural equation model (SEM) that examines the interdependence between the indoor environmental quality (IEQ), the working conditions, the atopic constituents and the reported health complains of employees in three Greek hospitals. The results of the SEM reveal that IEQ could partially explain the employees’ symptoms in the hospitals. The working conditions proved to be a key factor in the relationship between IEQ and symptoms. Multi-group analysis has shown that this interdependence is affected by the building characteristics, by the gender, the smoking habits and the specialty of each participant, but not by their age.     

Optimal execution with uncertain order fills in Almgren–Chriss framework

The classical price impact model of Almgren and Chriss is extended to incorporate the uncertainty of order fills. The extended model can be recast as alternatives to uncertain impact models and stochastic liquidity models. Optimal strategies are determined by maximizing the expected final profit and loss (P&L) and various P&L-risk tradeoffs including utility maximization. Closed form expressions for optimal strategies are obtained in linear cases. The results suggest a type of adaptive volume weighted average price, adaptive percentage of volume and adaptive Almgren–Chriss strategies. VWAP and classical Almgren–Chriss strategies are recovered as limiting cases with a different characteristic time scale of liquidation for the latter.     

A GPS data-based analysis of built environment influences on bicyclist route preferences

This study examines the effects of built environment features, including factors of land use and road network, on bicyclists' route preferences using the data from the city of Seattle. The bicycle routes are identified using a GPS dataset collected from a smartphone application named “CycleTracks.” The route choice set is generated using the labeling route approach, and the cost functions of route alternatives are based on principal component analyses. Then, two mixed logit models, focusing on random parameters and alternative-specific coefficients, respectively, are estimated to examine bicyclists' route choice. The major findings of this study are as follows: (1) the bicycle route choice involves the joint consideration of convenience, safety, and leisure; (2) most bicyclists prefer to cycle on shorter, flat, and well-planned bicycle facilities with slow road traffic; (3) some bicyclists prefer routes surrounded by mixed land use; (4) some bicyclists favor routes which are planted with street trees or installed with street lights; and (5) some bicyclists prefer routes along with city features. This analysis provides valuable insights into how well-planned land use and road network can facilitate efficient, safe, and enjoyable bicycling.     

海域"双评价"的实践与应用——以温州为例

"双评价"(资源环境承载能力评价和国土空间开发适宜性评价)作为构建国土空间基本战略格局的科学基础尚未延伸至海洋层面。海域"双评价"作为沿海地区国土空间规划工作的重要内容,存在理论缺失、技术方法不完善等问题。文章以海域功能理论为基础,从人类海洋活动出发,探索海域"双评价"的实践方案,建立"双评价"到海域利用优化的科学逻辑,指出基于"双评价"的海域利用冲突识别是海洋空间规划的关键。以温州市海域为例,基于本底资源从空间、渔业、环境和生态四方面进行单要素承载力测算,以此获得海域综合承载力作为监测预警的标志。选择渔业用海和建设用海两类典型用海进行适宜性分析,确定海洋空间利用的最优布局,判断海域利用空间冲突。结果表明:温州市沿海区县的海洋承载能力差异较大,资源环境分化严重,龙湾区与洞头区渔业资源开发超载;乐清市与龙湾区的海洋环境超载。渔业用海适宜面积占比较低且分布于远海地带。不适宜区域集中于瓯江、飞云江、鳌江三江入海口岸海域。建设用海适宜区域集中于近岸海域,远海区域距离城镇与交通较远,自然条件中水深较深,成本较高。苍南县和平阳县海域利用冲突较少,用海布局合理。乐清市、龙湾区与洞头区存在显著冲突。"双评价"的实践与应用是指导沿海地区海洋经济发展与海洋资源保护的关键,能够综合识别海洋利用的冲突,有助于沿海地区海洋空间规划。     

全球数字贸易规则博弈态势与焦点

社区公园是老年人户外活动的主要场所。研究社区 公园空间与老年人户外活动行为的关系,对于满足老年人活 动需求、应对人口老龄化问题具有重要意义。以南京市郑和 公园为研究对象,在实地测绘的基础上,定义公园空间的类 型,并分析各类空间的构成特征。选取公园中5个样本空间进 行观测,从时间和空间2个维度分析老年人公园活动的行为特 征。针对占公园活动人数绝大多数的8种活动,运用数据分析 和ArcGIS技术对行为与空间的关联性进行分析,结合访谈和 Nvivo质性分析发现,空间的尺度、围合性与开敞性、是否受 干扰、景观质量、庇护性是老年人活动空间选择的主要动因; 座椅、遮阴要素、大面积铺装、照明设施、置物设施等则是老 年人需要的空间要素。
