智慧城市建设对城市科技创新能力的影响

基于2008—2018年中国212个地级市面板数据,构建双重差分模型，评估智慧城市建设对城市科技创新能力的政策影响效应，并对城市异质性进行拓展分析。结果显示，智慧城市政策能够显著提高区域科技创新能力，且城市科技创新基础越好，政策效应越突出。据此提出智慧城市建设应从优化科技创新投入结构、共建协同创新平台、完善成果转化机制、优化创新空间布局等多个维度协力打造科技创新生态，整体提升科技创新实力。     

基于两次平衡计算的南昌市耕作层土壤剥离再利用空间配置研究

研究目的:探讨耕作层土壤剥离再利用空间配置思路与方法,并以南昌市为例进行实证研究,为相关工作提供借鉴。研究方法:提出基于线性规划及OD成本矩阵方法的两次平衡计算的耕作层土壤剥离再利用土方空间配置思路。首先,确定剥离、覆土优先度并结合供求关系划定供需圈,在供需圈内部进行第一次调配平衡;其次,对于内部不能平衡的供需圈,进行第二次跨圈调配平衡,达到缩短运输距离,控制成本目的。研究结果:(1)南昌市耕作层剥离量能够满足覆土数量与质量的需求;(2)空间配置结果共划定18个供需圈,供需圈内土方调配加权平均运输距离为6 682 m,小于期望值10 km,满足项目实施要求;(3)共有15个供需圈存在土方量不平衡问题,跨圈调配的距离平均为72 071 m,满足短距离运输的要求。研究结论:以耕作层土壤剥离、覆土优先度及供求关系为基础划定供需圈,基于线性规划及OD成本矩阵的两次平衡计算的空间配置思路与方法,可以优化运输距离,减少运输成本,提高项目实施效益。本文提出的空间配置思路可以为耕作层剥离再利用工程的顺利实施提供理论与方法借鉴。     

国家创新型城市对属地创新能力影响效应评估——政策动态过程与政企互动视角

选取2003-2016年城市数据样本，基于国家创新型城市分批次确立的特性，采用渐进双重差分模型、固定效应双重差分模型和处理效用双重差分模型，研究国家创新型城市对属地创新能力的整体效应、长期动态效应和批次效应。结合城市创新微观主体构成特性，分析属地国家创新型企业政策及企业类型异质性对属地创新能力的影响。结果显示：国家创新城市对属地创新能力提升在长短期均起到正向促进作用，且越早确立的城市对属地创新能力提升的作用效果越显著；国家创新型企业政策对城市创新能力提升起到正向调节作用，且企业集团作用大于上市公司和一般企业。最后，提出创新型城市建设相关政策建议。     

Brand and quality effects on introduction of store brand products

This paper considers a supply chain with a single manufacturer selling a national brand product via a single retailer. The retailer has the option to introduce a product under his own brand into the market with the same functionality as the national brand product. We simultaneously consider the consumer bases of the national brand and store brand along with consumers' willingness to pay for quality and the supply chain control (centralized vs. decentralized). By analyzing the game-theoretic models, we offer managerial insights about the influences of brands' consumer bases on the quality and pricing decisions of the retailer, and on the manufacturer's willingness-to-collaborate when the retailer introduces the store brand product. We find that, although it is usually easier for the retailer to introduce a product under a store brand with a large consumer base, doing so with manufacturers of well established national brands can be difficult, when the retailer often has to greatly mark down his store brand product's quality and price. We also find that a store brand product with a small consumer base shall be launched only when the supply chain is switched to a centralized control and when the manufacturer's national brand has a large consumer base. These important findings offer guidance to both national brand manufacturers and retail store managers regarding the launch of store brand products.     

National cultural effects on leverage decisions: Evidence from emerging-market ADRs

We examine leverage decisions in the context of national culture over the 1996–2010 period. Cultural characteristics can explain capital structure decisions from emerging-markets cross-listings. The results show that firms from countries with high Individualism and Indulgence employ more debt. Firms located in countries with high Power Distance, Masculinity, Uncertainty Avoidance, and Long-term Orientation are less leveraged. Additionally, Exchange-traded and capital-raising ADRs are more likely to be from countries with weaker corporate governance. Univariate tests show that capital-raising ADRs employ less debt relative to non-capital-raising ADRs, and notably, in the post-cross-listing period. Interestingly, the home country's cultural characteristics of capital-raising and exchange-traded ADRs exert less influence on their capital structure decisions. Our findings suggest that there is a value discount associated with increased firm leverage. Our insights have practical implications for portfolio managers attempting to enter emerging markets through the use of ADRs. Moreover, investors can evaluate the often neglected effect of cultural values into firm performance.     

Potential Spatial Labor and Human Capital Mobility in China: Evidence from College Admissions Under the National College Entrance Examination System

Abstract:

Higher education in China plays an important role in promoting labor and human capital mobility. In this paper, I empirically address the issue of regional disparities, college admissions under the National College Entrance Examination (CEE) system, and potential interregional labor and human capital mobility in China. The results show that examinees from western provinces have a strong preference for coastal universities, compared with examinees from central provinces. College admissions in China then seem to have a stronger effect on potential labor and human capital movement from the western to the coastal regions than from the central to the coastal regions.

基于相关与偏相关分析的城市居民休闲度假市场开发研究——以南京为例

我国旅游业正向休闲度假型转变。运用相关分析与偏相关分析方法,以南京为例探析城市居民休闲度假旅游需求。研究发现偏爱休闲度假的居民由于地位与收入的不同在旅游资源喜好、旅游活动偏好、购买行为、信息来源渠道、出游方式等方面与一般居民有着明显差异。因此,休闲旅游目标市场的定位应在高学历、中高收入阶层,旅游资源的开发应优先考虑湖泊水滨、森林山地,产品开发应注意项目与资源的耦合且促销渠道应以网络为主,兼顾传统媒介。
