我国区域产业转移的协调效应及发展趋势

我国自近代工业产生以来总共经历了四次较大规模的区域产业转移,呈现了特有的规律特征。作为区域资源配置的重要载体,我国区域产业转移对区域经济发展既有正面的积极效应,也有负面的消极影响。在新一轮国际产业转移和我国区域产业结构调整的推动下,以及一系列区域发展战略的实施,大规模的区域产业转移正在酝酿之中,未来的区域产业转移规模越来越大,层次越来越高,呈现新的发展趋势。     

基于变邻域搜索算法的物流配送系统集成优化研究

本文针对物流配送系统集成优化问题,考虑取货和送货两种业务的配送情形下仓库和车辆的容量上限约束,构建包括仓库的开放成本、配送成本以及容量溢出成本的非线性混合整数优化模型,设计变邻域搜索启发式算法对模型进行求解。算法通过泰森多边形确定位置上的初始订单分配,再通过扫描半径及消费者数据结构标识实现邻域搜索,改进算法对解决方案进行迭代更新,完成优化求解。最后通过对辽宁宅急送取／送一体化物流配送案例进行数值分析,验证算法可行性和有效性。     

处于后配额时代的中国纺织业

纺织品配额的取消对中国纺织业的发展既是机遇又是挑战,配额取消后,阻碍贸易的因素仍然存在,如美、欧盟的设限及反倾销。此外我国纺织企业本身存在很多不足,如出口现状仍是靠数量和低价取胜,品牌不具国际性等。我国纺织业若能借此良机,改变经营方式,提高品质,最终实现由中国制造向中国品牌的转变,才能自如参与“后配额时代”的全球竞争。     

How Network Strategies and Institutional Transitions Evolve in Asia

This article contributes to the literature on network strategies and institutional transitions in emerging economies in Asia by identifying a realistic, intermediate phase between the early and late phases of institutional transitions suggested by Peng (2003). Focusing on the intermediate phase, we advance two arguments based on network strength and network content. First, in terms of network strength, we leverage earlier insights that networks can be classified as strong ties and weak ties. Consequently, we suggest that as institutional transitions unfold, strong-tie-based networks, instead of being phased out, are being transformed into weak-ties-based networks. Second, from a network content standpoint, we argue that the various scale and scope of institutional transitions shape the content of different networks which focus on business-to-government (B2G) ties and business-to-business (B2B) relationships. Our propositions delineate how different transitions of political and legal institutions affect the evolution of B2G and B2B networks. Overall, we suggest that networks not only differ in strength but also in content, and that their evolution is driven by the impact of different dimensions of institutional transitions governing B2G and B2B relationships.

Peng (Ph.D., University of Washington) is a professor of global strategy at the University of Texas at Dallas, where he holds the university's first ever Provost's Distinguished Research Professorship. He was formerly an associate professor at the Fisher College of Business, The Ohio State University. He is the author of nearly 40 scholarly articles and three books, including, most recently, Global Strategy (2006). He has served on the editorial boards of AMJ, AMR, JIBS, and SMJ, and acted as a guest editor for JIBS and JMS. He is the first elected officer of the Global Strategy Interest Group at the Strategic Management Society. This is his fifth contribution to APJM. Jessie Qi Zhou is a Ph.D. candidate in international business at the Fisher College of Business, The Ohio State University. Her research interest includes strategy in emerging economies, network strategy, and organizational learning. Her main theoretical interest is institutional theory, with a focus on how institutional distance affects MNE strategies. The comparative analysis of firms' strategic choices across countries in response to different institutional environments is also of particular interest to her. Her work has been presented at the Academy of Management and Academy of International Business conferences.     

狼兽舍土壤源热泵系统运行特性研究

由于动物兽舍洞口为敞开式,围护结构保温性能较差,导致动物兽舍耗热量大,兽舍温度低,为达到兽舍需求的温度,并减少常规能源消耗,文章以狼兽舍为例,通过DeST软件对狼兽舍热负荷进行模拟分析,根据提出的峰值热负荷标准值以及土壤热物性参数计算打井深度及数量。利用TRNSYS软件分别模拟地源热泵系统在井间距5,6,7 m时的系统运行情况和土壤温度变化,结果表明当井间距为5 m和6 m时,土壤温度较低,无法满足系统长时间运行,当井间距为7 m时,土壤温度稳定在14.5℃,源测回水最低温度为6.03℃,供回水温差为4℃左右,系统运行效果最佳。因此对于狼兽舍土壤源热泵系统,满足供热需求的最佳井间距为7 m,井深为100 m,打井数量为20。研究结果为解决兽舍耗热量大,温度低等问题提供了解决方案,应用前景广阔。     

宜毕高速公路K3段震后边坡滑坡应急处置研究

为了有效控制震后山体滑坡、崩塌现象的蔓延,保证高速公路建设及运营安全,以震后宜毕高速公路K3段为研究对象,开展震后应急勘察工作,采取注浆、排水和反压等手段对边坡滑坡进行位移和沉降监测。利用Geostudio中的Slope/W模块分析加固后的滑坡稳定性,计算边坡的屈服加速度,提出根据预应力锚索进行加固的治理方案。结果表明,滑坡在地下水和地震的共同作用下产生,土体薄层状结构及岩层顺倾均加剧了滑坡形成,尽管地震作用对边坡整体稳定性有较大影响,但实施的应急处置措施遏制了滑坡的进一步变形,经过计算,边坡加固处理后屈服加速度为0.07g,安全系数为1.3,符合相关规范要求。可见,边坡滑坡体位移在震后初期得到了有效控制,治理措施有效提高了该边坡的稳定性。处置方案对类似高速公路的建设与维护具有借鉴意义。     

管理者盈利预测、过度自信与市场效应

管理者盈利预测在金融市场中具有重要的经济地位,我们选择了沪深两市2006-2009年的管理者盈利预测数据对管理者盈利预测与管理者过度自信、市场效应之间的关系进行了检验,与Hilary和Hsu的研究结论不同,我们发现:(1)管理者当前的盈利预测准确性会受到历史盈利预测准确性的影响,管理者在经历了较多的准确盈利预测之后会变得过度自信;(2)管理者在盈利预测上的过度自信会导致当前盈利预测的准确性降低;(3)管理者历史盈利预测的准确性并不会对市场造成明显影响,投资者和分析师在当前管理者盈利预测信息发布之后所做出的反应与管理者盈利预测历史准确的次数无显著的相关关系。本文的研究不仅丰富了国内有关盈利预测研究的相关文献,而且对提高我国资本市场上管理者盈利预测的准确性,加强市场参与者对上市公司信息披露的使用效率,进而提升投资决策具有重要的启示作用,同时对于我国监管机构完善信息披露制度具有重要政策意义。     

经济责任审计产生的动因和权力监督特征研究

理解经济责任审计产生动因是研究经济责任审计理论和推动实践发展的重要影响因素。文章从国家治理视角探讨了经济责任审计的产生动因,认为经济责任审计是中国政体国体及其权力运行现状下的特殊产物,是权力安全运行自律和自控的机制设计,是现行干部管理体制实践总结的制度完善,是中国特色国家治理的必然要求。籍此,文章分析了经济责任审计强调权力运行过程外部独立的监督、突出自上而下的权力监督和彰显经济权力行为监督等权力监督特征。     

Political rights and the cost of debt

We examine the impact of country-level political rights on the cost of debt for corporate bonds issued by firms incorporated in 39 countries. Similar to, but separate from, the relation for creditor rights, greater political rights are associated with lower yield spreads. A one standard deviation increase in political rights is associated with an 18.6% decline in bond spreads. We find evidence that political and legal institutions are substitutes; marginal improvements in political rights produce greater reductions in the cost of debt for firms from countries with weaker creditor rights. We examine potential factors through which political rights may affect the cost of debt and find that greater freedom of the press provides an important channel for reducing bond risks. Moreover, debt of firms with cross-listed equity trades at a premium in U.S. markets, but this relation appears to be more consistent with improved visibility than with bonding effects.     

以交易为目的的资产评估价值相关性研究——来自A股市场的经验证据

本文试图通过对我国上市公司资产重组中资产评估结果的确定及影响因素进行实证分析,来验证以交易为目的的资产评估的价值相关性。研究发现,不同重组方式对净资产的增值率没有显著影响,而不同评估方法下的评估结果则显著影响了净资产增值率;重组事件中评估标的物属于上市公司时,对市场没有显著影响,但长期股权投资则对股价有解释力。
