劳动密集型企业对世界经济的贡献是不容忽视的,但劳动密集型企业的优势却又会受到经济发展的冲击,因此研究劳动密集型企业意义重大。现有文献的研究多集中在对劳动密集型企业的概念、影响因素、某些具体行业、发展转型等方面,但仍存在研究不够深入、全面和与时俱进等不足,因此,未来的研究首先应有一个系统的研究思路,然后结合时代发展的特点,多行业多领域多角度的对其进行研究,以为其发展转型提供参考。  相似文献

The systemic change of 1989/1990 is usually identified as the critical juncture in the modern economic history of post-communist economies. While the change itself was indeed a remarkable moment in time, a branching point from which a multitude of new paths originated in most of the countries in Central and Eastern Europe, this was only partially true in the case of Hungary. If a critical juncture is sought for Hungary, it is more likely to be 1968, the year the New Economic Mechanism was launched. By applying the conceptual framework of historical institutionalism, the article argues that what made Hungary unique during the communist era and what rendered its position as a (one-time) frontrunner proved to be a serious constraint after the systemic change. The legacy of a pre-born welfare state, the constant need for compensating potential losers of any economic reform, along with short-sighted decision-making, have together generated specific path dependencies in the Hungarian trajectory of economic development.  相似文献

当前我国劳动关系出现集体化新趋势,这必将对中小企业劳动关系产生深远影响。为适应新趋势,中小企业首先要进一步规范个别劳动关系,并在此基础上逐步构建适合中小企业特点的集体劳动关系,同时要在理念、方式和机制上进行变革。  相似文献

收入和财富分配的不平等一直是中国改革发展中的重要问题。针对中国经济的特点,可以从政府改革的角度来研究如何更好地进行收入分配改革。地方政府主导推动地方经济的做法对收入不平等的扩大起了重要作用,加快政府职能转换,是使收入分配改革真正落到实处的破局之处,也是实现收入分配合理化可行的第一步。要改变地方政府的经济职能,降低它直接参与基础设施的程度,改革地方土地财政,建立垂直管理机构,以分散它的一部分经济管理职能,为收入分配改革打开空间。  相似文献

This paper examines the key factors that determine business traveler loyalty toward full-service airlines in China. Based on literature review and panel interview, ten airline attributes under three categories were derived: (a) operational factors: safety, punctuality, and aircraft; (b) competitive factors: frequency of flights, schedule, frequent flyer program, ticket price, and reputation; and (c) attractive factors: in flight food & drinks and in flight staff service. We surveyed 2000 Chinese business travelers on domestic flights, obtaining 462 usable questionnaires. Hierarchical regression analysis reveals that reputation, in-flight service, frequent flyer program, and aircraft have the greatest influence in driving airline loyalty.  相似文献

Wheat yields from reported performance test results are of economic importance to wheat producers, since their profits depend on selecting the optimal variety for their location. However, our data shows differences in absolute and relative wheat yields between commercial and public wheat breeding program's performance test data in Kansas. Newly available data are used to test if the difference in yields arose from potential selectivity bias, and to determine the contribution of private and public wheat breeding programs to varietal yield improvement during 2007–2012. Both Heckman selection models and multiple regression showed no statistical evidence of the potential presence of selectivity bias rather, managerial practices, agronomic conditions, field location, and inherent genetic traits of the seed variety were identify as the source of yield differences.  相似文献

The western Corn Belt region of the United States has become a hotspot for agricultural extensification and consequent land use and land cover changes. The goals of this research were to characterize geographic patterns of grassland loss resulting from cropland expansion in the eastern Dakotas, and to understand how these changes were associated with characteristics of individual farms and farm operators. We collected data on grassland conversion and other land use decisions through a mail survey of farm operators in North and South Dakota. Overall, 40% of respondents converted at least some grassland to cropland between 2004 and 2014, and the total acreage of converted grassland was equivalent to 5.1% of the surveyed farm acreage. Although most converted grassland acres (3.2% of farm acreage) were from land enrolled in the conservation reserve program (CRP), there were also substantial amounts of native grassland conversion (1.0%) and tame grassland conversion (0.9%). The total acreage of grassland conversion was more than four times larger than the acreage enrolled in CRP and other conservation programs. Different types of grassland conversion (e.g., native grassland versus CRP) were concentrated in different parts of the study region, and were spatially disjunct from the areas of highest conservation program enrollment. Larger farms were more likely than smaller farms to expand their cropland acreage and accounted for a disproportionate share of grassland conversion. Younger farm operators, higher levels of farm income, higher proportions of rented croplands, and marginal yields were also associated with cropland expansion and grassland conversion. Although CRP and other land retirement programs will remain important policy mechanisms for conservation in this region, they are not sufficient to maintain current levels of grassland cover and do not provide protection for native grasslands. Alternative conservation strategies and new agricultural policies are thus critically needed to maintain the ecosystem services provided by grasslands.  相似文献
