劳动力成本上升对不同规模企业创新行为的影响

现有研究认为劳动力成本上升会倒逼企业创新,但该结论主要基于规模以上企业实证研究,难以考察劳动力成本上升对不同规模企业创新行为的异质性影响。基于严格随机分层抽样的“中国企业-员工匹配调查”数据（CEES）,对劳动力成本上升背景下不同规模企业创新行为的异质性影响进行了大样本实证研究。将新产品推出速度作为企业创新的代理变量,研究发现劳动力成本上升对企业创新行为的影响在不同规模企业之间存在明显差异。大型企业创新速度显著加快,而中小企业的创新行为并未发现明显变化。进一步分析认为,之所以存在劳动力成本上升对中小企业创新的“倒逼失灵”现象,技能劳动力缺乏、职业培训投入不足和创新资金基础薄弱或是重要原因。     

Supply chain design under quality disruptions and tainted materials delivery

Events such as the 2008 Heparin tragedy, in which patients lost their lives due to tainted pharmaceuticals, highlight the necessity for supply chain designers and planners to consider the risk of even low probability incidents in supply chains. The goal of this research is to design a single-period, single-product supply chain model with capacitated facilities to hedge against the possibility of sending tainted materials to consumers. Given that our mixed-integer stochastic model is NP-hard, we develop efficient heuristic and metaheuristic algorithms to obtain acceptable solutions. Computational experience is presented and discussed.     

“新常态”增长的路径和支撑——深圳转型升级的经验

深圳转型升级的经验为"新常态"增长做出了两个理论贡献,即专业化分工和制度创新。改革开放30多年来,深圳顺利实现了"深圳加工—深圳制造—深圳创造"的产业持续跨越性升级。深圳经验的核心在于,不仅重视产业分工深化中所体现的市场自我发育过程,也强调政府通过制度创新,构建一个适于企业创新与学习的环境,支持企业分工专业化的创新过程,为产业升级奠定支撑基础,从而实现增长的"新常态"。

The Southampton econometric model

Four reasons are offered for presenting a paper on a now defunct model. First it was one of the very few attempts to construct a large-scale econometric model of the UK. Second, is its monetary sector — few models of that vintage had such a sector and, unlike modern models, its monetary sector was strictly Keynesian. Third is the explicit modelling of output and price equations. And fourth is the treatment of disequilibrium. Disequilibrium arises through the incompatibility of plans: total demand, for example, may exceed total supply and profits may be exceptionally high or unsustainably low. The rest of the paper gives a fuller account of the role of these disequilibrium terms in the explanation of price and output changes. Lists of equations and working papers are attached.     

Measures for evaluating supply chain performance in transport logistics

This study aims to investigate the construct of, and develop a measurement instrument for, supply chain performance (SCP) in transport logistics. Based on the supply chain operations reference model and various established measures, a measurement model and a measurement instrument for SCP in transport logistics are developed. A 26-item SCP measurement instrument was constructed, reflecting service effectiveness for shippers, operations efficiency for transport logistics service providers, and service effectiveness for consignees. The empirical findings suggest that the measurement instrument is reliable and valid for evaluating SCP in transport logistics.     

基于供应驱动的Supply Hub协同运作模式研究

供应及供应商在整个供应链协同中越来越重要,不仅要从需求出发,也要从供应出发进行供应链协同。本文分析了从供应出发进行供应链协同的新管理方式——供应驱动管理方式的核心思想,阐述了基于供应驱动的供应链协同运作典型模式——Supply Hub协同运作模式的发展,从整合库存、多方协同、匹配供应和直送工位的角度探讨了该模式的供应驱动力,构建了该协同运作模式的协同流程和方向模型,最后展望了以后的研究方向。     

IMF-Induced Structural Adjustment Programs and Women in Ecuador

This study examines the affect of IMF-induced structural adjustment programs on several key indicators regarding the status of women in Ecuador. In particular, we focus on the evolution of female primary and secondary school enrollment and female labor force participation in time series data from 1987 to 2003. The analysis is conducted using ordinary least squares regression with corrections for heteroscedasticity. The findings suggest that structural adjustment programs reduced female enrollment in primary and secondary schools and caused a reduction in the reported female labor force participation rate.      

劳动力市场是分割的吗?——"劳动力市场分割"经验研究文献综述

系统介绍国外在检验劳动力市场分割时所采用的各种经验方法,以及针对不同发达国家和发展中国家进行经验研究。这些经验研究所使用的数据既有横截面数据,也有时间序列和综列数据。综合这些研究,得到两个对于国内研究者具有现实指导意义的基本结论:一是在目前,总体来看,关于"劳动力市场是否是分割"这一经验问题并没有明确的答案;二是"二元理论"并未得到经验证据的有力支持。     

无固定期限劳动合同法律问题初探

无固定期限劳动合同是劳动合同的一种重要形式。新《劳动合同法》通过完善无固定期限劳动合同制度,加大对劳动者的保护力度。文章从无固定期限劳动合同的基本规定出发,论述了无固定期限劳动合同的特征、订立、解除等基本问题。同时,新法颁布后,对无固定期限劳动合同在实践中可能遇到的问题进行了初步分析。
