产品碳足迹及其国内外发展现状

气候变化已成为可持续发展的重要议题。低碳经济、低碳生活的号召下,产品生产及消费对环境的影响已渐渐引起人们的重视。产品碳足迹分析有助于企业真正了解产品对气候变化的影响,并由此采取可行的措施减少供应链中的碳排放。对碳足迹、产品碳足迹及产品碳足迹标识的相关概念进行介绍,分析国内、外有关产品碳足迹的发展现状和发展趋势。对社会普及碳足迹概念和引导更多中国企业实施产品碳足迹起到促进作用。     

中美汽车产业内贸易实证分析

产业内贸易水平越来越成为一国对外贸易竞争力及产业国际竞争力的一项重要指标。近年来,尽管中美汽车贸易发展迅速,但产业内贸易水平却较低。根据联合国商品贸易数据库数据,估算中美汽车产业内贸易指数,考察中美汽车产业内贸易的发展程度,剖析中美汽车产业内贸易的特征。研究得出:中国的产业内贸易总额超过产业间贸易,但产业内贸易水平仍低于美国;中美汽车产业内贸易产品的平均出口单价较低,平均进口单价较高,中国政府应引导汽车企业增大技术投入、引进国际领先技术、加强技术创新与产品研发。     

我国畜产品价格波动分析——基于ARCH类模型

运用ARCH类模型对我国主要畜产品的价格波动率进行了分析。结果表明:牛肉、羊肉和鸡肉的价格波动具有显著的波动积聚性,鸡蛋价格波动没有显著的异方差效应;除牛肉市场外,羊肉和鸡肉市场不具有高风险、高回报的特征;猪肉、牛肉、羊肉和鸡肉的价格波动没有非对称性。认为应在畜产品市场出现大的价格波动时及时采取平抑措施,且政府需规范畜产品市场秩序、完善畜产品市场制度。     

New product development in foreign customer relationships: a study of international SMEs

Abstract

This study identifies a gap in research concerning how small and medium-sized enterprises (SMEs) can benefit from pursuing locally (rather than globally) oriented internationalization strategies. Becoming overly dependent on one single foreign market could potentially reduce the inflow and diversity of new knowledge that can serve as input for new product development. This study discusses how this risk can be minimized. In this endeavour we create a theoretical model that investigates how the local sales concentration and relationship-specific commitment of SMEs relates to new product development. To do this we draw on the behavioural internationalization process framework. The theoretical model is tested on an effective sample of 188 Swedish SMEs. The results show that relationship-specific commitment mediates the effect of local sales concentration on new product development. The implication is that investments which enable collaboration in important business relationships are crucial requisites for keeping firms innovative and in pace with market fluctuations. The findings thus contribute to international business literature by showing that a local market scope of operations combined with a relationship orientation are beneficial for new product development in international SMEs.     

结算货币选择理论研究评述

国际交易媒介职能的发展关乎一国货币的国际化进展程度,该职能的微观市场表现即为国际贸易中企业结算货币的选择。基于此,本文对20世纪70年代发展至今的结算货币选择理论的研究进行了仔细梳理和阐释。伴随着欧元的发展,对该理论的研究经历了从纯理论到理论和实证相结合、从微观和宏观层面的独立研究到宏微观相结合的发展历程。在新开放经济宏观经济学视角下,企业结算货币选择模型将企业结算货币的选择从微观经济学层面转变为宏观经济领域的重要研究变量。文章最后,本文依托于相关理论并结合大量贸易数据,提出制约人民币国际交易媒介职能发展的重要因素即是我国出口产品差异化程度过低,企业缺乏竞争力。     

Where have all the flowers gone? Forecasting green trends in the automobile industry with a choice-based conjoint adoption model

With rising gas prices, global warming, and green thinking, all-electric vehicles are currently considered the automobile technology of the future. However, besides their advantages electric drive trains also exhibit several disadvantages. Moreover, history shows several failed attempts to establish electric vehicles. Thus, a reliable forecasting model is needed that predicts if the current trend is sustainable. We develop and empirically test a choice-based conjoint adoption model that uses individual-level preferences as a basis for prediction. Predictions are mapped to the time of the next planned purchase in order to establish the adoption process. The model extends existing research in several ways. First, no prior information, e.g., historical market data or a functional form of the adoption process, has to be integrated. Second, the model allows dynamic modifications of product specifications or competition at different points in time. Third, a no-choice option can be integrated so that a technology switch is not forced by the model itself and switching costs can be considered. The empirical results reveal different critical factors for the adoption of all-electric vehicles, such as purchase price, range, timing of the market entry, or environmental evolution, which could lead to a solid base of consumers preferring this option.     

Corporate governance structure and product market competition

This article assesses the effects of the competitive structure of a product market on a firm’s corporate governance structure. Our model demonstrates that shareholders strategically determine the corporate governance structure, including the manager’s stock ownership and his controlling power over the firm, in order to maximize their utility in the product market competition. We find that the manager’s stock ownership is lower and his controlling power over the firm is higher when the firm’s product is more profitable or when competition within the product market is more severe. The inefficiency of the wealth transfer from shareholders to the manager also affects the corporate governance structure.
