经济制度安排、国际贸易与经济增长影响机理的经验研究

本文分析了经济制度安排和贸易流量之间的相互关系及其对该国经济增长以及影响经济增长的其他因素的影响。在九个经济制度安排变量中对一国贸易流量影响作用最大的经济制度安排变量是该国的贸易政策,对一国高技术产品出口影响最大的经济制度安排变量是该国的产权保护程度。从对影响经济增长的渠道分析发现,在所有的经济制度安排变量中,一国产权的保护程度对该国经济增长的影响作用最大;同时产权保护的程度和政府干预对技术进步和人力资本的影响最为显著。     

The impact of data snooping on the testing of technical analysis: An empirical study of Asian stock markets

The primary aim of this study is to investigate the validity and predictability of technical analysis in eight Asian equity markets. We employ the bootstrap tests of White (2000) and Hansen (2005) to determine whether any superior trading rule is found to exist amongst the ‘universe’ of technical trading rules identified by Sullivan et al. (1999). We use these powerful bootstrap tests to ascertain the profitability of technical analysis, along with two institutional adjustments for non-synchronous trading and transaction costs. The empirical results indicate that these three elements, data snooping, non-synchronous trading and transaction costs, have significant impact on the overall performance of technical analysis; indeed, the results for these eight Asian stock markets support the efficient market hypothesis, demonstrating that the generation of economic profits through the use of technical analysis is extremely unlikely with these particular markets.     

Behavioral intentions of public transit passengers—The roles of service quality,perceived value,satisfaction and involvement

Understanding the behavioral intentions of public transit passengers is important, because customer loyalty is seen as a prime determinant of long-term financial performance. This study highlights such behavioral intentions and explores the relationships between passenger behavioral intentions and the various factors that affect them. Apart from the factors recognized by past studies, such as service quality, perceived value, and satisfaction, this study addresses the importance of the involvement of public transit services in passenger behavioral intentions. By using passenger survey data from the Kaohsiung Mass Rapid Transit (KMRT), a newly operating public transit system in Taiwan, we apply the structural equation modeling technique to analyze the conceptualized relationship model. The findings reveal that all causal relationships are statistically significant. Managerial implications are discussed.     

节约型园林的研究和采取的技术措施

近年来,由于观念上和认识上的偏差,使得园林绿化建设中存在着注重视觉形象而忽略环境效益的现象。因此,当前提出建设节约型园林绿化的口号,不仅十分必要,而且非常及时。     

F320-3DH钻机摩擦鼓的改制修复

F320-3DH钻机是70年代中后期从罗马尼亚进口的6000m大型石油钻机,大量使用了气胎式离合器。常因摩擦鼓与摩擦片的频繁摩擦,产生过热而导致摩擦鼓钢圈发生裂纹,严重时裂纹布满整个表面,有的裂纹穿透钢圈,有的甚至穿透至法兰联接筋板,造成摩擦鼓报废。摩擦鼓有几种不同规格,因装配位置不同,其内部筋板的联接结构方式也各不相同,互换性差或根     

中国各省市区种养业灰水足迹分析与评价

目的 深入挖掘第二次全国污染源普查成果，科学评价与分析各地区农业源水污染排放现状与环境压力，将有助于区域污染物减排与政策制定。方法 文章拟核算2017年中国31个省（市、区，不含港澳台）种养业的灰水足迹，构建评价指标体系，选取熵值法和理想点法作为综合评价方法，系统性评价与分析种养业水污染物排放量与产量、产值的协同关系，表征水污染物排放对区域地表水的环境压力。结果 （1）2017年全国种植业和畜禽养殖业灰水足迹分别为4 898亿m³和6 841亿m³，分别呈现“南高北低”和“东高西低”的地理分布特征。（2）畜禽养殖业水污染物排放带来的水环境压力大于种植业，尤其是黄淮海地区。（3）在种植业中，江苏和海南的灰水足迹综合评价结果相对较低；在畜禽养殖业中，河北、西藏、天津和宁夏相对较低。结论 建议种养业未来以减排增效为核心发展目标，海南优化肥料施用结构与方式、黄淮海地区调控种养业生产规模与方式、长江中下游地区拦截稻田退水污染。该文从水环境保护角度为中国种养业绿色发展提供政策建议。     

Schumpeterian Growth with Gradual Product Obsolescence

The model in this article captures several important aspects of the real world: gradual obsolescence of goods in the form of gradually declining net profit derived from each product until it is phased out, expanding variety of goods over time, and both dynamic and static internal increasing returns to scale of production. To eliminate the scale effect, Jones's specification that gives rise to a semiendogenous rate of innovation is adopted. The most interesting finding of the article is that, when the research duplication effect is small (large) relative to the intertemporal knowledge spillover effect in R and D, the decentralized market delivers insufficient (excessive) obsolescence and allocates too little (much) labor to R and D, while a small subsidy (tax) to innovation is welfare-improving. All these results hold because the positive knowledge spillover externality overwhelms (is overwhelmed by) the negative research duplication externality.     

基于个体特征和组织因素的员工离职原因分析

以某铁路局部分员工为研究对象,从个体特征和组织因素两方面对员工离职原因进行分析。研究发现,铁路运输企业员工离职倾向相对较强,但不同员工原因各异,对工作环境、工作愉悦性、保障性保健因素和职业发展前景、工作挑战性、自主性和报酬公平性等激励因素的关注程度也不同,需要针对不同员工采取不同的稳定人才策略,以达到留住企业需要人才的目的。     

Innovation capacity comparison of China's information technology industrial clusters: The case of Shanghai, Kunshan, Shenzhen and Dongguan

The aim of this paper is twofold: first, to explore the effects of industrial cluster on innovation capacity, and second, to study the impact of external resources on firms' innovation capacity especially under Chinese regional economic policy. This is a critical subject that lacks sufficient analysis. Through years of investment and effort, several IT industrial clusters have developed in China with Shanghai, Kunshan, Shenzhen and Dongguan the better-known examples. These IT industrial clusters were chosen for an empirical study on the disparities in China's innovation capacity. All of the innovation capacity determinants at these four IT industrial clusters were different. It was confirmed that the regional dimension of Chinese economic policy affects firms' innovation capacity in the industrial cluster. The results also show whether the regional policy differences will moderate the cluster effect on innovation.     

Board Gender Diversity,Auditor Fees,and Auditor Choice

We examine whether the presence of female directors and female audit committee members affect audit quality in terms of audit effort and auditor choice by using observations from a sample of U.S. firms, spanning the years 2001–2011. We find, after controlling for endogeneity and other board, firm, and industry characteristics, that firms with gender‐diverse boards (audit committees) pay 6 percent (8 percent) higher audit fees and are 6 percent (7 percent) more likely to choose specialist auditors compared to all‐male boards (audit committees). Our findings suggest that boards (audit committees) with female directors (members) are likely to demand higher audit quality, ceteris paribus.
