Chinese history is littered with sharp policy swings, and the communist era, which has not yet fully drawn to a close, has witnessed a veritable embarrassment of riches. This has provided a fertile ground for researchers engaged in crystal ball gazing. Recently, momentum has accelerated on that front, a development apparently reflecting the increasingly fluid political‐economic conditions in the country. The scenarios generated can serve as an effective reference point in planning exercises, but there is scope for solidifying the conceptual architecture. The issue of rendering them highly relevant to foreign investors, presumably very important potential consumers of the product, should also be addressed.  相似文献

为研究大倾角煤层开采过程中巷道围岩的稳定状况,以青东矿837机、风巷为工程背景,进行煤层顶底板岩石力学参数实验室测试,利用FLAC3D软件建立不同掘进工艺条件下的数值计算模型,分析软弱特厚煤层巷道分别在跟顶板掘进、全煤层掘进、破底掘进(不同破底深度)条件下巷道围岩破坏范围和变形特征。结果表明:跟顶板掘进方式下,围岩的塑性破坏主要发生在巷道底板下方,需要特别注意加强对底板的支护;跟底板掘进时,底板中部靠近帮脚处产生严重底鼓,应当加强对帮脚和巷帮的支护;在全煤层掘进时,巷道主要变形为底鼓与顶板下沉,顶底板破坏严重。研究成果对于指导大倾角厚煤层开采围岩控制具有一定的理论与工程意义。  相似文献

现代城市游憩商务区体系建设研究--以武汉市为例   总被引:6,自引:0,他引:6  
许峰  杨开忠 《旅游学刊》2006,21(3):24-29
游憩商务区及其相关概念是城市旅游空间利用的重要形式,本文在明晰基本概念与内涵的基础上试图厘清RBD、TBD和CTD之间的衍生关系,探讨游憩商务区体系发展演化的驱动机制和演进模式,并以武汉市为例系统地研究了在城市整体背景下如何面向市场依托现有资源建设RBD体系,以期为城市理性、科学地开发利用旅游空间提供参考.  相似文献

The fast pace of change will present many challenges in the new millennium. The success of the leader of tomorrow will depend on how well he or she is able to identify the forces that will drive change, invest in industry leading competitive methods that will take advantage of the opportunities presented by these forces and consistently allocate resources to these methods. Identifying the forces driving change is the most challenging aspect of this co-alignment concept. This paper explores the macroforces, which can be expected to drive change, and possible impact they will have on the hospitality organization. These forces include: globalization and economic change, a knowledge-based environment, the future of labor and quality in service delivery systems, and the growing consumer desire for improved well-being. These forces are presented along with the key variables making them up with the goal of understanding their complexities and interdependencies.  相似文献

This paper proposes a systematic accounting framework to decompose the reallocation of labour out of agriculture into factor market distortions and market-driven forces. The findings are twofold. First, the removal of factor market distortions is a dominant driving force of the structural change in China in the last decades, which contributes 50.52%, and market-driven forces account for the rest 49.48%. Second, the contribution of market-driven forces has been increasing with the deepening of market-oriented reforms, while the impact of the removal of factor market distortions has been decreasing especially along with the slowdown of labour market reforms after China joined the WTO in 2001. The results imply that further reforms that aim at correcting factor market distortions could still be an important impetus of structural change in the future.  相似文献

This article concerns the influence which alexithymia exerts on risk-taking. In particular, alexithymia is seen as a factor which encourages risk-taking as it allows high-alexithymia individuals to feel emotions which are sufficiently intense to compensate for their deficit of emotional awareness. In this connection, we make the hypothesis that alexithymia’s influence is moderated by private self-consciousness (SC). This is because private SC increases the likelihood that high-alexithymia individuals become aware of their risk-taking tendency and that this tendency is discrepant with their pro-safety standards (‘putting someone in danger is bad’) or self-schemas (‘I am a responsible person’). Thus, private SC is likely to enable and motivate them to consciously regulate their behaviour in a safer direction. This hypothesis was empirically tested by a questionnaire amongst 372 French drivers, whose SC, alexithymia, as well as their current adoption of eight risky behaviours (with a more detailed analysis of speeding). The use of conditional process analyses reveal no main effects of alexithymia and private SC but strong interaction effects, while controlling for other predictors. More precisely, when private SC is low high-alexithymia individuals break more the speed limits and adopt more frequently risky behaviours than low-alexithymia drivers. Conversely, when private SC is high, they are less risk-prone. As practical implication, we recommend the use of techniques increasing private SC amongst high-alexithymia persons.  相似文献

农村宅基地使用权流转推阻机制分析   总被引:3,自引:0,他引:3  
胡峰 《乡镇经济》2008,24(5):38-41
按规定,农村宅基地只有在农村集体组织内部和国家征收征用时流转,但实际上农村宅基地的流转十分普遍,特别是在城市郊区。文章分析了农村宅基地流转的驱动力和阻滞力,认为驱动力包括三个不同主体,即国家征收征用驱动力、农村集体组织转用流转驱动力、农户自发流转驱动力,主体不同驱动力不同。阻滞力包括制度阻滞力和区位阻滞力。  相似文献
