通过实证考察湖北、贵州两省近几年农村土地承包经营权流转的现状及对其成因的探析可以发现,中西部地区的农村要达致土地承包经营权规模化经营的理想状态,还有诸多制约因素有待克服。破解之道主要在于应构建有利于促进土地承包经营权流转的配套制度,营造有利于土地承包经营权流转的社会条件和经济环境。 相似文献

我国自2000年起进入人口老龄化社会,近年来人口老龄化趋势持续上升,提升基本养老保险制度的保障能力成为急需,其中,提高基本养老保险的统筹层次为完善养老制度的步骤之一.2011年,中共中央在"十二五"规划中做出明确指示,由社会统筹账户中的基础养老金部分率先实行全国统筹,但在具体实施过程中却有一定困难.实现城镇职工养老保险的全国统筹需要突破当前存在的瓶颈问题,采取切实可行的举措. 相似文献

A common dilemma a consumer faces during product return pertains to the decision of exchanging the product or obtaining a refund. This issue becomes even more salient for durable goods, when the initial purchase involves complementary products from different categories. This research examines consumer’s trade-off decision between returning and keeping complementary products by exploring various retail actions (using umbrella branded products (UBP)) and customer characteristics. We also investigate the trade-off between product exchange and refund when consumer returns a product. We find interesting extensions to past research wherein UBP are returned less and result in greater exchange than refund. Furthermore, an interesting caveat is that higher degree of complementarity between UBP intensifies the impact of various factors on exchange as opposed to refund of products. Implications for retail managers and sales teams are explored. 相似文献

In this study, we examined the role of guanxi as entrepreneurs’ resource-obtaining mechanism in private sector firms, using a data-set of 184 publicly listed firms in China. We found that guanxi indeed played a positive role that helped private sector firms gain easier access to resources. We also found that guanxi exerted even a greater positive effect on private sector firms’ resource obtaining compared to entrepreneurs’ political participation, due to being the lifeblood of business conduct and social interaction in Chinese culture. 相似文献

Do ongoing networks block out new friends? Reconciling the embeddedness constraint dilemma on new alliance partner addition 下载免费PDF全文
Research Summary: This study addresses a theoretical dilemma regarding how alliance network constraint (reflected by network cohesion) affects a firm’s alliance formation with new partners. Using a network pluralism approach, we separate a firm’s ego alliance network into two activity‐based networks—an exploratory network and an exploitative network—based on the primary value chain activity involved in each alliance. We argue that the cohesion of exploratory or exploitative networks has an inverted U‐shaped effect on the addition of new partners in the same activity‐based network, and a positive effect on the addition of new partners in the other network. Results based on data from the biotechnology industry largely support our predictions with one exception. Our study contributes to both scholarly understanding of network embeddedness and alliance practice. Managerial Summary: The structure of firms’ ongoing alliance networks may have paradoxical implications for their efforts to search for and form alliance with new partners. That is, when a firm’s alliance partners are tightly connected with each other, the cohesive network tends to both encourage and impede the focal firm to add new partners. We resolve this dilemma by showing that when a firm is deeply entrenched in a cohesive alliance network conducting a certain type of activities (e.g., R&D activities), it may not easily add new R&D alliance partners. However, it may still be able to escape from the cohesive R&D alliance network by seeking new partners conducting other activities (e.g., manufacturing activities). 相似文献

The main goal of this research was to merge the theory of planned behavior and the norm activation theory into one model and test its applicability in an environmentally responsible museum context. A filed survey was conducted at museums. Structural equation modeling was used to test research hypotheses. Results of the structural model comparisons revealed that the prediction power of our integrated model was superior to that of the theory of planned behavior and the norm activation theory. The proposed relationships among research constructs were generally supported. The mediating role of study variables was established. Additionally, the salient role of personal norm and attitude in generating museum travelers’ pro-environmental intention was identified. Overall, there was a strong support for the proposed theoretical model. 相似文献

Greening is one of the most important issues faced by the tourism industry today. Nevertheless, theoretical and empirical research on young travelers’ sustainable behaviors is scarce. This study developed a conceptual framework involving biospheric value, environmental concern, environmental awareness, ascribed responsibility, and moral norm in order to better explain young travelers’ pro-environmental decision-making process. A total of seven hypotheses were proposed and tested using structural equation modeling. Results revealed that the postulated theoretical model satisfactorily accounted for three dimensions of young tourists’ environmentally responsible intentions; the study variables are all significantly related; and the mediating impact of moral norm and environmental concern was evident. Moreover, the prominent role of moral norm in forming intentions was noteworthy. Our findings from the invariance test further indicated that environmental awareness and ascribed responsibility acted as moderators. The implications of these results are discussed. 相似文献
