区域发展视角下我国连片特困地区精准扶贫及脱贫的思考

精准扶贫战略提出以后,理论界和实践界对于精准扶贫与片区攻坚的关系应如何把握而产生了不少困顿。连片特困地区这一提法早已有之,经过一系列的政策演变,在区域发展和减贫方面也取得了非常显著的成效,但仍需解决如何应对“经济新常态”下区域发展带动减贫效应的削弱、进一步提升片区攻坚减贫效率、多维贫困问题、消解片区的贫富分化、协调发展等一系列问题。解决这些问题的关键在于实现精准脱贫精准扶贫与片区攻坚融合发展,具体而言就是要以区域发展为视角、提升片区定位精准度,以多维贫困为视角、提升减贫内涵精准度,以精准扶贫为视角、提升脱贫手段精准度,构建精准扶贫与片区攻坚融合推进的新机制。     

采购拍卖下混合回收渠道的闭环供应链奖惩契约协调研究

在市场需求不确定下,应用采购拍卖和奖惩契约研究零售商和第三方混合回收的闭环供应链协调问题。针对市场中存在m个制造商、1个零售商和1个第三方回收商的情形,分析目录拍卖-双重奖惩契约机制协调供应链的影响,证明当参数满足一定条件时目录拍卖-双重奖惩契约机制能够协调闭环供应链。     

A Qualitative Study on Home Modification of Rural Caregivers for People with Dementia

Opinions about the responsibility for procuring sheltered housing in Norway have been studied among people 50 and older. Until recently, Norway offered standard public provision, where the state has been the central provider and organizer of care for the elderly. The results indicate great support for public responsibility for providing sheltered housing for the frail elderly, which is only marginally affected by background characteristics. However, older people's attitudes as to whether they would choose private housing provision are affected by income, age, and knowledge of the market, and many are uncertain. Women and low-income groups are overrepresented among those who are uncertain.     

明北京城营建石料采办研究

明代定都北京以后,大规模的营建工程在历朝持续进行。作为基础建筑材料,石料在明代已经得到广泛应用,明北京营建工程对石料产生巨大需求。为此,明政府开始了大规模的石料采办活动。本文具体阐述了北京营建工程所需石料的种类、产地、采办和运输过程。明代北京营建石料采办在采运成本、运输组织、时间安排等方面均有周到的考虑和合理的安排,这是石料采办工程得以顺利进行的重要原因。

我国政府采购制度中的缺陷及对策探讨

政府采购是指国家机关或公共事业单位及其授权的组织为了公共利益或自身机构的运转或职能的需要而使用公共资金进行的对货物、工程和服务的采购行为。我国政府要履行加入GPA的庄严承诺,就应根椐国际采购规则的基本要求,结合我国实际情况,建立透明而公正的政府采购机制。     

Managing stochastic demand in an Inventory Routing Problem with transportation procurement

We study an Inventory Routing Problem in which the supplier has a limited production capacity and the stochastic demand of the retailers is satisfied with procurement of transportation services. The aim is to minimize the total expected cost over a planning horizon, given by the sum of the inventory cost at the supplier, the inventory cost at the retailers, the penalty cost for stock-out at the retailers and the transportation cost. First, we show that a policy based just on the average demand can have a total expected cost infinitely worse than the one obtained by taking into account the overall probability distribution of the demand in the decision process. Therefore, we introduce a stochastic dynamic programming formulation of the problem that allows us to find an optimal policy in small size instances. Finally, we design and implement a matheuristic approach, integrating a rollout algorithm and an optimal solution of mixed-integer linear programming models, which is able to solve realistic size problem instances. Computational results allow us to provide managerial insights concerning the management of stochastic demand.     

Fostering innovation through innovation friendly procurement practices: a case study of Danish local government procurement

Innovation has been at the forefront of procurement policy in Denmark in recent years. The policy incentives emphasize public procurement of innovation as a way to accelerate the development and application of environmental and health technologies, but also as a way to achieve a competitive advantage, growth and job creation. This paper uses a single case study to illustrate the procurement of a chemical-free cleaning system by the local government in Denmark. It describes the public procurement of innovation project in the response to an unsolicited bid from the supplier, and highlights the importance of innovation-friendly procurement practice for supporting innovation. The study identified indirect innovation effects of public procurement and number of conditions that have supported success of public procurement of innovation project such as close and early engagement with supplier; role of supplier acting as a technology champion; competence for applying functional specification; political support; sufficient resource allocation and institutional match between involved organizations. These findings lend support to the idea that public procurement of innovation may have occurred as a result of innovation-friendly procurement practice regardless of the lack of an explicit intention to promote innovation and challenge assumptions on which emerging policy initiatives are based on. These findings also suggest that the local government procurement may have a role to play in supporting innovation that goes beyond current definition of public procurement as a mission-oriented instrument to be exploited for resolving social challenges. These understandings could contribute to further policy development that may lead to a situation where public procurement of innovation is utilized to a greater extent than it is today in Denmark.
