基于普惠金融发展的家庭网络消费行为研究*

网络消费作为一种新型消费业态和模式,已成为扩大内需的新力量。本文应用Probit模型及处理效应等方法,在普惠金融发展视角下研究了家庭的网络消费行为。结果显示,普惠金融发展显著正向地提升了网络消费家庭的比例和频率,且经过渐进的增长,网络消费家庭的总消费水平更高、消费结构较优,在城镇家庭里更明显。而通过便利支付、缓解流动性约束、提高家庭收入三种机制,普惠金融发展还提升了这些家庭的网络消费支出额。异质性分析也得出了一系列丰富的结论。加深家庭金融参与程度,加快地区数字普惠金融的发展,帮助老年群体、低收入群体迈过数字鸿沟,能更大程度上普及网络消费,进一步扩大内需。     

Not quite paradise: Inadequacies of environmental impact assessment in the Maldives

The Maldives, a Small Island Developing State (SIDS), has seen a rapid development of its tourism industry over the last 35 years with visitor numbers rising from 1062 visitors per year in 1972 through to over 600,000 today. Both in popular conception and reality the Maldives relies on its marine life and beaches to sustain a tourism industry that contributes over 30% of total GDP.     

Corporate diversification: the impact of foreign competition,industry globalization,and product diversification

The globalization of markets and industries has fundamentally changed the competitive conditions facing firms. Yet, how globalization has influenced the international diversification strategies of firms is an issue largely overlooked in both the strategic management and international business literatures. This paper develops a theoretical framework to understand how industry globalization, foreign competition, and firm product diversification may influence a firm's choice of its degree and scope of international diversification. Utilizing a panel dataset of U.S. manufacturing firms for the period 1987–99, we provide the first empirical evidence that industry globalization and foreign-based competition are statistically significant factors explaining the degree and scope of international diversification by U.S. firms.

中国非公有制林业制度创新框架

This article analyzes the form and the mechanism of non-public forestry＇s institution obstacles by classical economies, institution economics＇, legal economics and economic theories of modern forestry. Regarding the proprietary institution as the core, and cost-income as the main clewf-it defines the concept and eategory, of non-public forestry subsidy and compensation. And oecorrling to the relased control and efficiency principle of market econonf-this paper establishes a set of institution that accords with the development of non-public forestry, offers both theoretical supports and decision- making references to remove institution obstacles of nan-public forestry, and coordinates the policies of non-public forestry with those of the public-owned forestry.

关于《钢铁行业生产经营规范条件》(工原[2010]第105号)的博弈研究

我国钢铁行业近年来一直面临产能过快增长、布局不合理、铁矿石流通秩序混乱和资源环保压力大等问题,为了促进这些问题得到解决,国家工业和信息化部于2010年6月出台了《钢铁行业生产经营规范条件》。本文从涉及该规范条件执行的中央、地方和钢企三方利益博弈的角度进行分析,指出博弈各方从自身成本收益角度可能采取的策略选择和行动,并最终对该规范条件的执行效果产生影响。最后,结合博弈研究推导的结果与当前政策执行的现实困境,本文提出了相关的政策建议。     

Matching method to paradigm in strategy research: limitations of cross‐sectional analysis and some methodological alternatives

A central focus of empirical research in strategic management has been to understand the relationships associated with the structure–strategy–performance paradigm. To examine these relationships, investigators have relied extensively on cross‐sectional methods that embody the implicit assumption that model parameters are stable across firms and over time. Yet, many of the theoretical constructs used in strategic management have clear firm‐ and time‐specific components. Hence, it might be expected that the parameters of the relationships investigated empirically will vary across firms and over time. Whereas recent research has raised concerns about the use of cross‐sectional analysis when parameters vary over time, little attention has been given to the issue of parameter variability across firms. Given the focus of strategy researchers on firm‐level effects and the predominant reliance on cross‐sectional analysis, accounting for across‐firm variability is a significant methodological issue. Failure to account for such variability can lead to biased parameter estimates and incorrect inferences. This paper argues for the adoption of alternative methods that can overcome the limitations of a cross‐sectional analysis and it offers guidance on how researchers can proceed to use these alternative methods to explicitly incorporate or test for variation in model parameters across firms or over time.

Sex discrimination in selection and compensation in Taiwan

This article describes the current status of women in the workplace in Taiwan. Statistical evidence shows sex segregation in the labour market. Discriminatory practices in the hiring process are documented via a content analysis of 7,037 classified ads. Overtly discriminatory actions, such as blatantly stated gender requirements in the classified ads, are shown to be still common in hiring practices. Census data on a gender gap in compensation shows that women in Taiwan evidently get less pay than men do for the same work. The ratio of female to male employees is significantly and negatively correlated with the ratio of female to male in pay. The higher the percentages of women in an industry, the lower the pay women get compared to men. Also, the ratio of female to male in pay is negatively related to the turnover rate. Companies that pay women fairly tend to enjoy lower turnover rates. The implications of these women's issues in human resource management in Taiwan are presented.
