This paper develops a tractable model of examining how factor heterogeneity and imperfect factor market interact for determining a pattern of trade. Institution plays a crucial role for the interaction. In my work, firm productivity is defined as a composition of factor productivity and technology. Thus, input selection should affect the pattern of Melitz’s intra-industry allocation due to the incurring transaction cost. For a simple model, I assume two factors (labor and capital) and two sectors, which are relatively less institution-dependent and relatively more institution-dependent. When the economy is open, effect of the transaction cost on income distribution is more drastic for an institutionally underdeveloped country. Depending on institutional quality, the economic openness reallocates resource across countries through job creation or job destruction. The job turnovers redistribute income between heterogeneous labors within countries. The income redistribution is catalyzed by international mobility of capital. As a result, income disparity is widened between the institutionally developed country and the institutionally underdeveloped country. This paper can contribute to the literature of institution and international trade.  相似文献

[目的]以高分1号(GF-1)融合2m卫星遥感影像为基础数据源,结合土地利用现状数据、高分多源遥感影像和地面样方等数据,对冬小麦分类提取中存在的面积误差问题进行研究和分析。[方法]文章以河南省永城市为研究区,在冬小麦提取结果聚类处理基础上,基于线性地物缓冲区数据,采用GIS空间运算实现线性地物面积扣除,接着分析了样方数据和土地利用现状数据再扣除零星地物面积比例上的差异,并采用样方零星地物平均扣除系数对全市各乡镇耕地与非耕地中冬小麦提取面积进行了相关统计和误差分析。[结果]永城市冬小麦最终解译面积11. 29万hm~2,其中线性地物和零星地物扣除面积分别为6 613. 08hm~2和3 875. 22hm~2,占研究区冬小麦解译面积的5. 86%和3. 32%,与统计上报数据相比,其处理前后误差由14. 12%降低至4. 41%,有效地提高冬小麦提取面积精度。[结论]误差来源分析与修正对冬小麦解译面积核算精度具有重要影响,该研究为县级区域尺度下冬小麦面积提取核算提供了思路和借鉴。  相似文献

This study aims to empirically evaluate the predictors that influence sustainability performance among manufacturing firms. Leadership and management, green and lean practices, and guanxi were examined to determine whether these predictors are directly and/or indirectly affecting sustainability performance; 160 valid responses were collected and partial-least-squares-structural-equation-modeling (PLS-SEM) was used to analyze the data. The results showed that leadership and management positively influenced green and lean practices and green and lean practices positively influenced sustainability performance. Leadership and management also positively influenced guanxi. Interestingly, leadership and management and guanxi do not exert a significant direct influence on sustainability performance. The findings contributed to the development of the resource-based-view theory further by empirically exploring the significance of leadership and management coupled with green and lean practices as competencies and capability to drive sustainability performance. The testing of the dual mediators' effects further added value to this study.  相似文献

从自我提升视角出发,基于社会比较理论与社会交换理论,分析组织支持感影响员工创造力的过程机制,相对组织支持感的调节作用以及情感承诺与创造力之间的曲线关系。基于458份企业员工与主管的配对样本,研究结果表明:相对组织支持感显著正向调节了组织支持感与情感承诺之间的关系,情感承诺与员工创造力呈显著的倒U型关系,情感承诺在组织支持感与创造力关系之间起到了瞬时中介作用。研究结果拓展了对组织支持感的影响机制及其边界条件的分析,深化了情感承诺与员工创造力关系的检验。  相似文献

Although a growing body of literature has touted e-participation as a means of facilitating greater citizen participation in policy decision-making processes, little is known about the driving forces behind citizens’ use of e-participation. Based on a literature review of social capital and citizen participation, this study develops and tests a model proposing that three dimensions of social capital and three dimensions of citizen participation management should be positively associated with e-participation in agenda setting. Using data from a Korean e-participation survey conducted in 2009, we found that citizens tend to be more active e-participants when they have greater trust in government and are weakly tied to offline social groups. We also found that citizen participants’ perception of government responsiveness to their input can facilitate their e-participation. The study findings imply that local governments should pay more attention to the function of public trust in local government and provide quality feedback in response to citizen input. They should also be sensitive to how the social factors of e-participants can facilitate involvement in agenda setting.  相似文献

This paper examines how power affects consumers’ responses to corporate social responsibility (CSR) initiatives of luxury brands. The results of three studies show that high‐power individuals evaluated a luxury brand's CSR campaign more positively than low‐power individuals. High‐power individuals viewed CSR activities as being more fluent than low‐power individuals. This study further demonstrates that power influences consumers’ responses to nonluxury brand's CSR activities. Low‐power individuals, who are more receptive to warmth, evaluated nonluxury brand's CSR more favorably rather than high‐power individuals.  相似文献

地基处理技术是近年来我国房屋建筑工程施工中一种较常见的施工处理技术,多见于房屋建筑工程中的软土地基施工环节。通过以往的房屋建筑经验,如果直接在软土地基上进行建筑施工,地基区域软土很容易会影响房屋建筑工程的稳定性,所以,在针对这一部分软土区域的施工环节,需要针对拟施工的地基软土区域进行处理,提升其软土的稳定性。到目前,地基处理技术已经在我国房屋建筑工程施工中广泛应用,这一技术应用过程中存在的不足也逐渐凸显,如何针对这一技术的不足予以完善,以此提升地基处理技术对房屋建筑质量的积极影响,成为了现阶段房屋建筑地基基础施工质量提升的重要环节之一。  相似文献

The primary purpose of this study was to examine factors that influence the effectiveness of benefit appeal types (i.e., help-other vs. help-self) in Corporate Social Responsibility advertising. To that end, we designed and administered a between-subjects experiment where participants viewed one of the two CSR advertisements crafted with help-self and help-other benefit appeals. Results provided evidence supporting the moderating effects of status-consumption motives and age on purchasing intentions. Additional analysis suggested consumers younger than 48 years old were more likely to be persuaded by a help-other ad appeal when they didn't have strong desires for status consumption. Results were discussed in light of the self-concept theory and value-expressive framework in CSR advertising.  相似文献
