Promotion and Prevention Contracts in Industry Level Firm to Firm Dyad

ABSTRACT

Purpose

This article aims to introduce and distinguish two features of contract design – prevention and promotion contracts – and compares their effects on opportunism within the distributor–supplier relationship. It also examines the moderating role of ex post contract enforcement strategies.     

去工业化、技术差距与产业转移的技术溢出效应

中西部承接产业转移缺乏显著的正向技术溢出效应，成为2000年后区际技术差距持续扩大以及近年部分地区过早去工业化的关键影响因素之一。利用2001~2017年全国30个省（市）面板数据研究证实，各地区技术水平与工业增加值在地区生产总值中的份额之间存在显著正相关性；中西部在2005~2014年承接了较大规模产业转移，而区际技术差距却持续扩大，技术溢出效应显著为负。在相对偏低的技术水平条件下，中西部地区在十余年的产业承接中主要依赖于廉价的要素成本优势，其自主创新能力、创新资源积累已不足以抵御本地消费升级、要素成本上升与国际需求疲软等负面因素的叠加影响。最终，技术差距、商品及服务净输出赤字的扩大至少加快了部分欠发达地区的去工业化。     

Personalized goal-based investing via multi-stage stochastic goal programming

In this paper, we propose a goal-based investment model that is suitable for personalized wealth management. The model only requires a few intuitive inputs such as size of wealth, investment amount, and consumption goals from individual investors. In particular, a priority level can be assigned to each consumption goal and the model provides a holistic solution based on a sequential approach starting with the highest priority. This allows strict prioritization by maximizing the probability of achieving higher priority goals that are not affected by goals with lower priorities. Furthermore, the proposed model is formulated as a linear program that efficiently finds the optimal financial plan. With its simplicity, flexibility, and computational efficiency, the proposed goal-based investment model provides a new framework for automated investment management services.     

供给侧改革视角下的养老旅游产业发展研究--以广东省阳江市为例

供给侧结构性改革作为适应和引领经济发展新常态的重大创新,用改革的办法对错配的供需结构和扭曲的要素配置进行矫正,根据需求结构变化及时优化供给结构,实现资源优化配置和经济长期均衡发展。阳江作为滨海旅游城市,应抓住机遇,深化养老旅游产业供给侧结构性改革,优化养老旅游产业的供给结构,合理配置养老旅游资源,扩大养老旅游服务的有效供给,推进养老旅游产业的持续健康发展。     

劳动异质情况下的产业结构偏离及其影响因素分析——基于2006～2013年全国产业行业数据

本文充分考虑劳动异质性，利用产业人力资本结构，重新核算三次产业结构偏离度，发现第一产业和第三产业结构偏离程度均被高估，第二产业结构偏离被低估，进而指出“民工荒”、大学生就业难等现象产生的原因是第一产业可转出人力资本减少，第二产业需求旺盛，而第三产业由于发展不足陷入低水平均衡状态。最后通过系统的影响因素分析发现，解决我国结构偏离和就业问题的重点在于优化需求结构、合理规划产业发展路径以及全面推进城镇化和市场化进程，关键更在于释放农村消费市场巨大潜力和全面加快第三产业发展。     

Analysis of LPG,electric and induction cookers during cooking typical Ecuadorian dishes into the national efficient cooking program

This research aims to analyze cooking parameters in liquefied petroleum gas (LPG), electric resistance and induction stoves for eight dishes of the Ecuadorian cuisine. During tests, it has been monitored the temperature, time, electrical grid parameters, concentrations of CO and CO₂. In addition it has been studied the microbiological and physiochemical changes produced by the thermal treatment in food and a discriminative triangular test for determining the differences in the consumers perception between samples made with induction and LPG based stoves. The results showed which even with an exhaust hood working, there was still a significant value of concentration of CO and CO₂ during cooking with a LPG stoves. As a result of these analyses the induction stove shows a better response during the heating process and energy efficiency which have influence in temperatures, taste, vitamin preservation, cooking times, energy consumption and cost to the user.     

经济全球化背景下产业集群对高职教育的影响

在国际金融危机的传导效应显现后,我国产业集群面临了极大挑战。为此,要进一步加强企业、政府、行业协会、高校与科研院所等社会组织间的联系与合作。本文通过分析推导出高职教育能够为产业集群输送所缺人才,而产业集群又为高职教育提供了很好的发展前景的这一辩证统一关系。在这一关系的基础上,继而分析在当前的产业集群面临的挑战的现状下,高等职业教育将会面临的挑战及发展思路。     

影响失地农民再就业的原因分析与政府作为

失地农民再就业一直是党和政府着力解决的"三农"问题之一。从消除制度缺陷、提供培训资金支持、拓宽非农产业就业渠道、搞好就业培训等方面采取的措施尚未见到实效。失地农民再就业受到收入水平、生活成本、工作环境、技能要求、地区经济发展等因素的影响,政府应当在注重产业布局和调整的同时适度保留劳动密集型产业、加大公共财政保障力度,强化用人单位培训责任、系统设计失地农民权益保障制度等方面入手,破解失地农民"被城市化"后的再就业困境。
