周一上班,打开电脑的人们突然发现公司局域网的论坛上惊现了一些照片,内容都是一妙龄女郎和一老年男人的床上照,两人皆一丝不挂,与最近外网上流传的香港娱乐圈的艳照类似。虽然照片经过了技术处理,但群众的眼睛是雪亮的,认出那男的是公司采购部的赵总,那女的是他们部门的杨经理,环境是在星级宾馆的房间里。这样一来,所有人的周末综合征的倦怠情绪一扫而空,兴奋得两眼放光,就像打了     

山村札记

车子一直往南。窗前掠过的建筑物渐渐少了。不一会儿,便看见了大片的农田,平日被高楼大厦挤压的心胸一下子被撑长起来,呼吸也顺畅起来,大口大口的满是苞谷秸秆的清香混着新翻的泥土味儿。秋收后,田野像是准备迎娶新娘子的房间,被粗手大脚的庄稼汉拾掇得干干净净。约莫又过了两、三刻钟,依稀     

资源型城企物流耦合系统系统动力学分析

一、资源型城企物流耦合系统的提出 由于煤炭、石油、有色金属等不可再生自然资源的开采期限受资源储量的限制,因此,这类资源型企业的转型将成为必然.我国资源型企业多拥有自己的物资部门,负责生产材料的采购、存储、供给以及产品的销售、运输,随着生产的不断扩大,资源型企业的物资部门的规模、功能不断扩张,形成相当的物资供给能力.     

对我国矿产资源开发及利用的市场化问题分析

大多数矿产资源的开发和利用是需要国家介入和有效配置的.矿产资源属于不可再生资源,其储量和可开采量都是既定的.有效应用市场手段优化配置资源的开发和利用是具有战略意义的,在未来的发展中如何把握好资源的使用限制及开发形式都是关系到国家核心竞争力强弱的重要举措.本文从我国市场经济的进程和未来总体经济平衡发展以及充分利用资源创造更多的社会福利的现实需要出发,运用相关的理论方法就我国现行条件下矿产资源开发及利用的市场化过程中的几个核心问题加以分析.

进入 21世纪,生态失衡、资源枯竭等全球性问题日益严峻,作为解决这些问题的对策之一,循环经济理论受到人们越来越多的重视.循环经济这一概念,发轫于 20世纪 60年代,以" 3R"( Reduce, Reuse, Recycle)为原则,旨在减少对资源的消耗和对环境的污染,以保持经济的可持续发展.与此相适应,循环经济评价指标体系和测算方法也得到了广泛的研究.本文在掌握丰富材料的基础上,对近年来国内外关于循环经济的研究成果进行了总结和述评,指出了目前研究中存在的问题和今后的发展方向.     

Pesticide residues and trade,the apple of discord?

In this paper we study the impact of the regulations on Maximum Residue Levels (MRLs) of pesticides on the trade of apples and pears and related processed products with the aim of understanding how their similarity (or dissimilarity) affect trade. Most studies investigate the impact of sanitary regulations introducing directly in the analysis the MRL put in force in the importing country. They introduce in the analysis the level of the regulation in the importing country without taking into account the rule in force in the exporting country. Rather than focusing on a particular pesticide we take into account the entire list of substances set out by the various regulations. We then build a similarity index and introduce it into a gravity equation to assess the impact of the differences in MRL of pesticides on trade. Results suggest that the differences between regulations matter and may, in some case, hinder trade.     

Politics,policy and fixed-line telecommunications provision: Insights from Australia

Over the past 40 years, telecommunications policy worldwide has been dominated by the privatisation of former government-owned firms, the pursuit of increasing competition as well as the delegation of day-to-day operations of industry decision-making and oversight from core governments to autonomous regulators sitting at arms-length from political decision-making. One of the most (apparently) dramatic reversals of this trend has occurred in Australia where the federal government has set up a state-owned company (NBN Co) to fully replace and upgrade the fixed-line infrastructure for voice and broadband communications for the entire country. Some argued that the NBN heralded a reversal of a “failed, neoliberal” deregulation and pro-competition policy agenda in Australia, and a return to “social democratic” values. The NBN has attracted interest as a possible model for other governments looking to fund broadband infrastructure.The NBN Co's network is nearing completion. It has proved disappointing in many ways, with costs escalations, missed deadlines and a downscaling of the original full-fibre footprint to a mixed technology model (MTM). It has also proved politically divisive, with some claiming the MTM changes represent the reassertion of a neoliberal political agenda. In this paper, we trace the evolution of the fixed-line telecommunications industry in Australia from the 1980s to the present along the dimensions of privatisation, deregulation and competition in voice, broadband and policy settings. We find that contrary to popular political rhetoric, the Australian industry reforms have been characterised by only a partial and inconsistent progression towards the international policy objectives. In particular, ongoing government ownership of the incumbent created perverse incentives for both regulatory and industry actors and ensured political involvement in import network investment and operations decisions which in other jurisdictions are delegated to private-sector owners and regulators at arms-length from political influence. We contend that the NBN was not a social democratic response to failed neoliberal policies, nor was the MTM a neoliberal reassertion. Rather, the politicisation of the NBN is a function of the inability to decentralise ownership and control of the industry away from the government. These issues will continue to dominate the Australian debate, as the statutory context requires the privatisation of the NBN within five years of its projected 2021 completion. Extreme caution is warranted for jurisdictions looking to the NBN model for guidance.     

Decomposition analysis of the telecommunications sector in Indonesia: What does the cellular era shed light on?

Indonesia is currently enjoying rapid development in the telecommunications sector despite the economy having been heavily dependent for almost four decades on the two largest sectors: the manufacturing industry and trade. The telecommunications sector has played an important role in stimulating economic growth in the country during the last few years, with an annual growth rate higher than that of other sectors. This contribution is supported to a great extent by the rapid diffusion of telephony, in particular cellular telephony, as the number of subscribers increased from just 2.1 million in 1999 to 170 million in 2011. Previous studies investigating the impact of the telecommunications sector on the economy aggregate the impact of the sectors on Gross Domestic Product (GDP) without further scrutiny of what sources of growth telecommunications has contributed. Hence, an interesting question arises as to whether the achievement of cellular diffusion is also followed by structural change in the telecommunications sector. That said, this study aims to decompose the output of telecommunications into several sources of growth: domestic final demand, export effect, import substitution effect and technological coefficient effect. A particular interest in this study is to compare the source of growth concerning domestic final demand and the technological coefficient effect. The main tool for analysis in this study is the Input–Output (IO) method, while the time series of the investigation covers the period 1975–2008, allowing comparison of structural changes in the telecommunications sector between the pre- and post-cellular eras. The study found that the coefficient multiplier of the telecommunications sector, which was approximately 1.8 during the 1980s, had decreased to only 1.3 by the end of 2008. Consequently, the final demand from the telecommunications sector contributed less to economic output in the late 2000s compared to the impact in the 1980. Moreover, the cellular era that started in the early 2000s also brought about a trend of changes in telecommunications output. While final demand remains very dominant, the technological coefficient effect has diminished as the source of telecommunications output. This finding indicates a lower ability of the telecommunications sector to build an inter-industry relationship with other sectors. A possible explanation for this result is the cellular uses which are much less related to business activities than that of fixed telephony dating back to the 1970s in Indonesia.

The effects of M&As within the mobile ecosystem on the rival's shareholder value: The case of Google and Apple

As a result of the speed of information and communications technology convergence, the concept of the business ecosystem has been adopted for understanding the business value chain. Within the business ecosystem, keystones play a central role. Currently, Google and Apple are the keystones of the mobile ecosystem, and they have been quite active in acquiring firms over the past years. This study empirically examines the effects of these two firms’ mergers and acquisitions (M&As), especially the different effects on the acquirer and the rival depending on the type of target firm. After the target firms are classified according to the businesses of the acquiring firm that each target firm is related to, the study examines the effects of different types of M&As on the values of the acquirer, the rival, or both. The results provide a basis for understanding the complex relationship between two keystones within the mobile business ecosystem.     

A framework for understanding individual response to regulation

Regulations to encourage behaviour change are often used by governments to achieve policy objectives. The success of regulations depends on the commitment of individuals to change behaviour in ways that comply with regulatory obligations. Understanding and predicting the motivation of individuals to change their behaviour is critical in assessing the likely effectiveness of proposed regulations. In this paper we present a novel framework for understanding and predicting the motivation of an individual to comply with regulations. The framework is based on two central ideas. The first idea uses the involvement construct to predict the motivation of individuals to comply. The second idea separates the influence of the regulation on individuals’ motivation to comply from the influence of the underlying policy issue on the motivation of individuals to comply. Through application to a case study we show the framework’s merit in predicting an individual’s possible behavioural responses to a regulation and how it assists regulatory agencies develop strategies to enhance compliance.     

Wireline deregulation: The Canadian experience

Changes in the state of telephony markets paved the way for significant regulatory and legislative reforms in the telecommunications sector in the 1990s. In Canada, the 1993 Telecommunications Act was enacted to promote the emergence of competitors in a market that had until then been dominated by regional monopolies. This paper examines the Canadian telecommunications regulatory framework and analyzes the regulatory privileges given to new entrants at the expense of former telecommunications monopolies. Such regulations, which were meant to induce competition, ended up hurting consumers and distorting the market process. This paper also shows how the Canadian government recently eliminated many of those regulations by seizing control of the policy agenda from the telecommunications regulator.     

Total factor productivity enablers in the ICT industry: A cross-country firm-level analysis

Advancements in productivity in the digital economy constitute an important engine for economic growth. What drives productivity dynamics in the information and communication technology (ICT) sector? This study examines the productivity dynamics of ICT firms across countries from the perspective of corporate balance sheets. We study the effects of intangible assets and leverage on productivity growth using firm-level panel data from five industrialized countries. We find that intangible assets positively affect the total factor productivity in the ICT sector. The positive effect of intangible assets on total factor productivity growth is larger for ICT manufacturing firms than for ICT service firms. We also find that leverage has a positive relationship with total factor productivity development in the ICT sector. In addition, our empirical results substantiated that productivity is catching up to the technological frontier. Furthermore, larger firms and/or younger firms generally show higher total factor productivity growth than their peers. Economies of scale are more prominent in the ICT service sector than in the ICT manufacturing sector. Our findings contribute to the understanding of cross-country productivity dynamics in the ICT sector at the firm level in the digital economy.     

Japanese distribution system: The impact of newly designed collaborations on wholesalers' performance

In January 1995, the Kobe earthquake devastated a major part of Kobe's distribution infrastructure. Apart from the expected complaints about lost sales, wholesalers reported some surprising comments after the reopening. Wholesalers stressed the advantages of newly designed distribution channels, especially the opportunity to end longstanding business relationships known as keiretsu. This study is concerned with the recent development of vertical collaboration in the Japanese distribution channel. Multiple regression analysis revealed that the supplier's service to wholesaler, the supplier's offerings to the wholesaler, and buyer's service to the wholesaler did contribute to the enhancement of the performance of the wholesaler. The three factors explained 16% of the wholesaler's performance. The regression analysis also showed that the wholesaler's intra-logistics activities contributed to the improvement of the performance of the wholesaler and explained 5% of its performance.     

Diffusion and usage of public e-services in Europe: An assessment of country level indicators and drivers

We analyze the state of the art of indicators on e-government, e-health, e-procurement and e-participation. We survey the main methodological properties of these indicators, and highlight their heuristic potential. Further, we address empirically the issue of the explanation of the availability scores, i.e. how the supply of the various e-services in each country is affected by political, institutional and socio-economic differences, and is followed by actual usage. The econometric analysis uncovers the importance of broadband penetration and higher education as drivers for most of the types of e-services and users (citizens and businesses). Moreover, a corruption-free and agile public sector proves to be an important pre-condition for more effective supply and usage. Despite data limitations and the complexity of the underlying diffusion phenomena, our study is the first truly longitudinal contribution aimed at disentangling the common drivers of such an important phenomenon – the e-services availability and usage across European countries. As such, this work appears useful to inform the policy debate and practice, in a phase characterized by a prospective reorientation of the public e-services provision and policy agenda.
