Can stable environmental protection officials’ tenure reduce illegal emissions?

Based on the day-night PM_2.5 difference of the nearest atmospheric monitoring points to measure whether there is illegal emission, this paper explores the impact of environmental protection officials' tenure (EPLT) on illegal emissions. The results show that there is a positive correlation between EPLT and illegal emissions. Stable EPLT can reduce illegal emissions by increasing environmental information disclosure and environmental subsidies. It can increase illegal emissions by weakening public pollution reporting and media supervision, environmental law enforcement and promoting corruption. In addition, EPLT can increase illegal emissions as EPLT is less than 3.55 years, while EPLT can increase illegal emissions as EPLT exceeds 6.21 years. Further, when mayor's tenure and EPLT are both stable, the promotion effect of EPLT on illegal emission is stronger. Stable company director's tenure can also aggravate the promotion effect of EPLT on illegal emissions.     

中国高端装备制造业自主技术创新效率稳定性及影响因素研究

在全面实施创新驱动发展战略的时代背景下，揭示中国高端装备制造业自主技术创新效率稳定性，测度相关因素的影响强度与方向，对揭示中国高端装备制造业自主技术创新规律，制定其发展策略具有重要指导意义。聚焦中国高端装备制造业自主技术创新效率稳定性及影响因素，采用DEA-Malmquist指数方法和Tobit回归模型进行实证研究，结果表明，中国高端装备制造业自主技术创新效率存在一定波动性，且各细分行业技术创新效率内部稳定性较差，产业自主技术创新效率整体稳定性不高；自主技术创新投入因素和环境影响因素对产业自主技术创新效率的影响具有较高的异质性，其中创新资金投入和人力资源投入对自主技术创新综合效率、纯技术效率及规模效率具有正向影响，而新产品开发投入和企业规模对自主技术创新综合效率、纯技术效率和规模效率的影响具有异质性，政策因素与市场因素分别具有显著和非显著负向影响，外源性创新因素具有显著正向影响，且影响强度较大。在此基础上，提出调整政府对高端装备制造业创新支持模式、加强外源性创新与智力引进等策略建议。     

基于技术轨道的制造企业服务化机理研究

基于技术轨道理论与制造企业服务化间的关系，认为技术轨道对制造企业服务化的影响机理包括3类：驱动机理、拉动机理和差异化机理。制造企业服务化转型内在机理是技术轨道驱动下投入服务化、企业边界变化以及用户需求、产出、政策拉动下与技术轨道的协同演化过程，且通过技术轨道形成服务化转型差异。制造企业对自身技术轨道的识别有利于确定发展所需主要技术来源及技术演化轨迹，把握实现服务化的关键机理。

Service procurement in manufacturing companies: Results of three embedded case studies

An increasing part of companies' purchasing expenditures is being spent on (business) services. At the same time, the interactive character of business services has so far largely been neglected in purchasing and supply management studies. The success of a service purchase is however established during the ongoing production and consumption of that service, which takes place in continuous interaction between buyer and seller.This paper investigates these ongoing interactive processes between buyer and seller after the purchase decision has been made. The specific focus is on services buying by manufacturers, since manufacturers' services spend increasingly encompasses services that eventually become part of the final offering to customers. This is expected to pose specific challenges for manufacturing companies, who have traditionally been involved with purchasing goods.Case studies into ongoing buyer-seller interaction are conducted at three manufacturing companies. Starting from a usage-based classification which contains four types of business services, four services are studied at each manufacturing company. The results show that indeed the different types of services can be associated with distinct patterns of ongoing interaction. Furthermore, the results provide initial support for the idea that having differentiated patterns of interaction contributes to successful ongoing service exchange.

Unlocking the potential of advanced manufacturing technologies

This research examines whether investments in advanced manufacturing technologies (AMTs) such as flexible manufacturing systems (FMS), computer aided design (CAD), computer aided manufacturing (CAM), robotics, etc., are more likely to lead to improved performance if they are supported by improvements in the manufacturing infrastructure of the company. This question is evaluated using data gathered from 202 manufacturing plants chosen from industries generally considered to have relatively high investments in technology.Multiple item scales are developed and adapted from sources in the literature to measure investments in technology, infrastructure, and the performance of the plant. Evidence supporting the reliability and validity of these scales is provided. Hierarchical regression is used to analyze the relationship between technology, infrastructure, and performance. The results suggest that there is an important interaction between the adoption of advanced manufacturing technologies and investments in infrastructure. Firms that invest in both AMTs and infrastructure perform better than firms which only invest in one or the other. Separate analyses on sub-samples of firms with the highest and lowest investments in AMTs show that infrastructural investments have a stronger relationship with performance in the high investment group. Thus, the data indicate that infrastructural investments provide a key to unlocking the potential of advanced manufacturing technologies.
