下属潜能的开发——论企业人才从何而来

对企业而言，面对日益激烈的竞争，如何赢得或保住市场都是极为严峻的挑战。能够帮助企业迎接这一挑战的核心竞争力，便是来自高素质高技能的队伍——人才。企业缺乏合适的人才，如若采用挖墙脚方式虽可解救燃眉之急，但无法长期满足企业成长的需要，因此企业应着重于从内部培养。管理人员的一个最重要的职责就是有效地培育与发展下属，并激励团队成员为组织的目标全力以赴。从公司内部培养和提拔业务骨干和中层管理人员，对企业的长远发展来讲是一件非常重要的事情。公司的每位中、高级管理者都有培养下属的责任。但多数企业并没有下大力气实施人才培养，这其中有观念的问题也有实际的障碍。     

An Eclectic Approach to Estimating U.S. Potential GDP

Rennison (Comparing alternative output gap estimations: a Monte Carlo approach, 2003) has provided simulation-based evidence showing that the joint use of extended multivariate filters and structural vector autoregression models is optimal for estimating potential output. We use this approach to estimate the two components of potential GDP: the full-employment labour input and trend labour productivity. This decomposition is useful for identifying sources of fluctuations in potential output. It reveals, for example, that the vigorous growth rate of U.S. potential GDP recorded during the second half of the 1990s is attributable to a fall in the structural rate of unemployment and a marked upswing in trend productivity growth.

市场潜力、经济集聚与地区间工资差异

基于劳动力、产业在地区间分布的不平衡性以及地区间工资差异的事实,本文构建了一个市场潜力与工资的新经济地理学(NEG)理论模型。理论分析表明:市场潜力对工资产生正面影响。市场潜力对工资产生正面影响来自两种渠道:一是市场潜力引发了经济集聚效应;二是市场潜力产生了逆经济集聚。相比之下,市场潜力引发了经济集聚效应更能提高和扩大地区工资水平与差异,因为经济集聚需要更低的贸易成本、较大的市场规模以及较高的经济发展水平。     

Spatial and temporal analyses of potential land use conflict under the constraints of water resources in the middle reaches of the Heihe River

With the rapid urbanization in China, land resources are becoming increasingly scarce. Identifying and resolving land use conflict is essential for reasonably using land resources and achieving land sustainability. Taking the middle reaches of the Heihe River as an example, we included the constraints of local water resources to construct a multi-criteria evaluation system for assessing land use competitiveness in 2000 and 2015 based on land use, socio-economic, and nighttime light data. By comparing the competitiveness of cultivated land, construction land and ecological land, we then derived the spatiotemporal patterns of potential land use conflicts. Actual land use changes supported the hypothesis that land use tended to convert into the type with higher competitiveness at areas with intense conflict, which better indicated that our assessment model was effective. The results showed that the potential land use conflict was more acute in the central and northwest but weak in the southeast and northeast, and its pattern showed a significantly positive spatial autocorrelation. The conflict between cultivated land and construction land was most prominent and mainly occurred in the transitional zone from urban to rural areas. Rapid urban development and water shortage were the main causes of the potential land use conflict. Assessing land use multi-functions and making a tradeoff among ecological, economic, and social services will be an effective way to guide future land use to solve land use conflict. Our research provides scientific evidence for sustainable land use planning and management in the arid areas.     

巴中市农田土壤重金属分布及生态风险评价

[目的]通过测定秦巴山区巴中市农田土壤中镉(Cd)、铅(Pb)、锌(Zn)3种重金属元素的含量及分布特征,为农田重金属防治科学决策的制定提供数据支撑。[方法]文章采用内梅罗指数和潜在生态风险指数来综合评价巴中市土壤重金属污染状况。[结果]巴中市农田土壤锌平均含量比四川省丘陵地区背景值高6.78%,而镉和铅含量均未超出其背景值,总体评价良好,但各检测点之间差异较大,镉含量最多超出背景值5.7倍。内梅罗指数评价结果显示,全市平均综合污染指数为1.10,接近清洁状态。潜在生态风险指数评价结果显示,其最小值为15.94,最大值为177.74,平均值为35.38。[结论]巴中市农田土壤重金属污染状况基本处于低度风险级别,但各地块污染程度不尽一致,应因地制宜,采取适当措施治理土壤污染。     

技术并购能够带来技术创新效应吗 ——收购公司成长潜力视角

选择2009—2017年我国A股高科技产业上市公司并购事件作为研究对象,考察技术并购能否给收购公司带来技术创新效应,以及收购公司成长潜力水平对技术并购与技术创新效应的调节作用,并进一步从两维度区分不同类型技术并购以检验其技术创新效应差异。结果发现：技术并购能够显著带来技术创新产出效应和技术创新促进效应;收购公司成长潜力越大,技术并购带来的技术创新效应越显著。此外,相对技术进入型并购,技术巩固型并购更能给收购公司带来显著技术创新效应,而国内技术并购与跨境技术并购带来的技术创新效应不存在显著差异。

Spatial Pattern of Tourist Flows Among the Asia-Pacific Countries: An Examination over a Decade

The spatial dimension of tourism provides insights about travel demands and travel flows and helps destinations in planning, development and management. The last decade has witnessed a steady and rapid growth in the Asia-Pacific region's tourism industry, in terms of both inbound and outbound travel. This particular study aimed to: (a) provide information and explore the changes on the nature of travel flows as measured by the tourist arrivals among the Pacific Asia Travel Association (PATA) member countries for the years of 1995 and 2004; (b) assess general propensity to travel among PATA countries using the concepts of Country Potential Generation Index and Gross Travel Propensity; and (c) examine the shift in the past decade in terms of the relative tourism generation power of PATA countries by comparing and contrasting the 1995 and 2004 indices. The results of the study provide an overview of the spatial patterns of travel flows and travel propensity in Pacific Asia region over a 10-year period. The study demonstrates that the functions of travel flows and indices are complementary and provide an informative picture of spatial travel behavior and demand.     

知识联盟R&D投入与绩效的关系——基于知识势差视角的研究

研究了知识联盟R&D投入与绩效的关系,构建了基于知识势差的知识联盟R&D投入与绩效的关系模型,并进行了数学分析。研究认为:知识势差是知识联盟的成因,它从根本上影响着R&D投入与绩效的关系;绩效是知识水平和合作意愿的函数,联盟绩效应着重考虑企业知识水平的变化;R&D投入与绩效之间不呈现显著的正相关关系;要达到一定的知识势差,R&D投入才对绩效产生显著的正向影响;R&D投入过大反而会造成绩效的下降;合作意愿越强,R&D投入对绩效的正向影响越显著。
