政府质量、市场化程度与现金—现金流敏感性——来自后金融危机时期的经验证据

在中国式经济增长进程中,政府作为"幕后推手"日益引发各界关注。政府的质量取决于政府所提出的制度安排,而企业行为是对政府所制定的制度的反应。本文以2009—2011年我国上市公司经验数据为样本,检验政府质量、市场化程度与现金—现金流敏感性间的关系。实证结果发现,随着政府质量的提升,企业运用内部现金流积累现金的倾向减弱,表现为现金—现金流敏感性降低。同时发现,这种变化在不同市场化程度地区的企业中会呈现不同的特征。具体而言,伴随政府质量的提升,市场化程度较低地区的企业受惠于制度环境的优化,其现金—现金流敏感性显著降低,而市场化程度较高地区的企业这一变化并不明显。本文为解释地方政府推出制度优化经济环境的微观机制提供了经验证据。     

Which commercial partners are important for the most recently admitted EU countries?

This paper describes the degree of trade integration inside the European Union (EU) after the fifth enlargement in 2004. To achieve this goal, we build a database of information on trade flows between the new EU countries (EU‐10) and 180 commercial partners in six different sectors from 1999 to 2011. Using the standard gravity model and estimating a difference‐in‐differences specification, we analyze how joining the EU affected the intensity and direction of the EU‐10's trade flows. Our results show that though trade exchanges between the EU‐10 and EU‐15 intensified after 2004, the impact of integration was much more significant to the EU‐10 group.     

How knowledge flow affects Korean ICT manufacturing firm performance: a focus on open innovation strategy

The paper presents an integrated viewpoint of technological innovation strategy by considering both the firm and industry levels. Further, we provide a new open innovation framework by adopting a knowledge flow perspective using patent citation information. Finally, we consider a firm’s outbound open innovation performance using cites per patent information together with financial performance to look at both the practical and the potential effects of technological innovation strategy. Through these analyses, this study examines determinants of open technology innovation activity in the information and communication technology manufacturing industry in Korea and draws managerial and policy implications for effective industry promotion and improvement of technology innovation capability.     

Political travel constraint: The role of Chinese popular nationalism

This study extends the leisure constraint model by examining the role that popular nationalism has in Chinese outbound travel. Using a case study approach based on the 2012 Diaoyu/Senkaku Island Incident between China and Japan, the study demonstrates how Chinese popular nationalism has the potential to shape the geopolitical environment of all outbound Chinese tourism. The study proposes a new model that can be used to illustrate how popular nationalism may affect bilateral tourism in other settings. Findings of this study offer important insights for both scholars and practitioners contributing to the understanding of the impact of Chinese popular nationalism on bilateral tourism flows.     

A network approach to modeling the multi-echelon spare-part inventory system with backorders and interval-valued demand

A multi-echelon inventory system implies the existence of a hierarchy of stocking locations, and the dependence and interaction between them. We consider a multi-echelon, spare-part inventory management problem with outsourcing and backordering. The problem is characterized by deterministic repair time/cost, and supply and demand that lie within prescribed intervals and that vary over time. The objective is to minimize the total inventory and transportation costs. We develop a network model for problem analysis and present a network flow algorithm for solving the problem. We prove that the Wagner-Whitin property, known for the lot-sizing problem, can be extended to the spare-part inventory management problem under study.     

国际资本流动对我国就业影响的均衡分析

文章通过建立一个劳动力市场与资本市场的均衡模型,对国际资本不流动与国际资本不完全自由流动两种情况下的分析表明,国际资本流动加剧了国内劳动力市场的就业风险,并且国际资本流动对就业水平影响与本国资本市场的开放度有关,增加开放度有利于提高本国的就业水平.我国应在采取有效措施减小国内劳动者就业波动的同时,逐渐提高资本市场的开放度.     

一种一维距离像的识别算法

随着高分辨率雷达的发展,一维距离像识别已成为雷达目标识别的重要方法之一.为了消除一维距离像的平移,将一维距离像变换到频域,提取其频谱信息作为识别特征,并依据Fisher判据,将高维特征空间数据降到一维空间,提高了算法的实时性.仿真结果表明这是一种方便有效的识别方法.     

风景名胜区国内客源市场动态分析及其意义——以南京钟山风景区为例

随着旅游业的发展,旅游行业的风景名胜区,要通过实地考察和问卷调查等方法,对风景名胜区国内旅游者的构成现状、旅游流强度、空间分布进行动态分析,这样才能为开拓客源市场、调控旅游超载、旅游客流预测等提供建设性意见。     

家庭净收益视角下的农村劳动力转移决策研究

“个体流动”和“家庭转移”是两种不同的劳动力转移形式,而稳定性的人口转移应该是“家庭转移”。追求家庭净收益最大化是“个体流动”或“家庭转移”的直接动因。农户的转移过程可分为初始阶段(流动前阶段)、个体流动阶段和家庭转移阶段,分析各个阶段家庭净收益影响因素,“个体流动”是增加农民收入的有效途径,而较高的城市生存成本是制约“家庭转移”的根本因素。     

旅游流在区域内聚:从自组织到组织--区域旅游研究的一个理论框架

首次提出并研究"旅游流的区域内聚"现象.根据系统的自组织与组织原理,以江浙沪地区为例,研究在旅游流的区域自组织演化中所形成的旅游中心城市,并研究以这些旅游中心城市作为节点而形成的区域空间结构和基于这种区域形态的区域旅游空间组织.
