国家级农业科技园是当前正在迅速兴起的实现农业现代化的有效形式之一,兼顾农产品生产、农业高新技术示范、种苗繁育技术示范培训及旅游观光等多种功能。湖南望城国家农业科技园是我国第一批批准成立的国家级农业科技园。自2011年望城县撤县变区后,望城区成为长沙市的重要组成部分,也成为了全国唯一一个以整个行政区域作为科技园区的国家级农业科技园,而其功能定位与分区、产业结构等则需要与长沙市区进行匹配整合协调。本文以望城国家级农业科技园为例,根据其既是行政区又是农业园区的特点,协调相关规划,对其功能定位以及功能分区进行研究探讨,并据此指导园区的规划布局。  相似文献

本文选取2000年-2017年新疆15个地州(市)为样本,运用索罗残差法计算全要素生产率、资本和劳动力投入对经济增长的贡献率。研究发现,新疆目前处于规模经济阶段,增长方式为资本密集型,技术进步在经济增长过程中的作用逐渐减弱。其中,少数民族高度聚居的南疆地区处于规模报酬不变阶段,粗放式经济增长特征较北疆地区更明显。同时发现,第二次中央新疆工作座谈会召开后,新疆各投入要素结构逐渐优化,供给侧结构性改革成效初显,正从规模速度型粗放增长逐渐向质量效率型集约增长转变。基于此,本文从扩大开放格局、促进少数民族地区技术进步、完善人才引进和培养机制、合理配置投入要素资源等方面提出优化新疆高质量发展路径的政策建议,为促进全国少数民族地区高质量发展提供参考。  相似文献

While it is widely claimed in the literature that convexity is correctly priced, we find evidence in four major swap markets that this is the case only on average and that extended periods occur when convexity-based trading strategies offer economically very significant exceptional returns. These abnormal returns can be reaped with fully no-peek-ahead strategies and after accounting for transaction costs. We find a strong link between the periods of highest profitability and conditions of reduced market liquidity. This suggests that, as observed in recent liquidity studies on US Treasuries, temporary deviations from market efficiency at the long end of the swap curve occur when pseudo-arbitrageurs do not have sufficient capital to correct the mispricings.  相似文献

Beyond merely satisfying customers, companies are increasingly striving to build deeper and more meaningful customer relationships characterized by strong customer-company identification. However, whereas previous research has solely focused on symbolic drivers of identification, it remains unclear whether, when, and how managers can build on core functional company characteristics (i.e., quality, innovativeness, and price) to establish customer–company identification. The present study addresses these questions by developing a theoretical framework based on theoretical notions of social identity theory and the cue diagnosticity framework. Evidence from two field studies and one experimental study shows that functional company characteristics are not effective in creating customer–company identification per se, but that their influence depends on whether they match with a self-definitional need that is important to the customer (i.e., self-continuity, self-distinctiveness, or self-enhancement). The findings also reveal the underlying mechanism of this contingency by showing that a self-definitional need fosters customer–company identification because it strengthens the symbolic value of a matching functional characteristic. By identifying specific characteristic–need matches, this research offers novel insights into how managers can leverage functional company characteristics in their targeting and communication efforts to establish meaningful long-term relationships with customers.  相似文献

This paper proposes a component approach to systemic risk which allows to decompose the risk of the aggregate financial system (measured by Expected Shortfall) while accounting for the firm characteristics. Developed by analogy with the Component Value-at-Risk concept, our new systemic risk measure, called Component ES, presents several advantages. It is a hybrid measure, which combines the Too Interconnected To Fail and the Too Big To Fail logics. CES relies only on publicly available daily data and encompasses the popular Marginal ES measure. CES can be used to assess the contribution of a firm to systemic risk at a precise date but also to forecast its contribution over a certain period. The empirical application verifies the ability of CES to identify the most systemically risky firms during the 2007–2009 financial crisis. We show that our measure identifies the institutions labeled as SIFIs by the Financial Stability Board.  相似文献

Abstract

Objective: This retrospective database analysis estimated the incremental effect that disease progression from non-clinically significant functional mitral regurgitation (nsFMR) to clinically significant FMR (sFMR) has on clinical outcomes and costs.

Methods: Medicare Fee for Service beneficiaries with nsFMR were examined, defined as those with a heart failure diagnosis prior to MR. Patients were classified as ischemic if there was a history of: CAD, AMI, PCI, or CABG. The primary outcome was time to sFMR, defined as pulmonary hypertension, atrial fibrillation, mitral valve surgery, serial echocardiography, or death, using a Cox hazard regression model. Annualized hospitalizations, inpatient hospital days, and healthcare expenditures were also modeled.

Results: Patients with IHD had higher risk (Hazard Ratio?=?1.22 [1.14–1.30]) for disease progression compared to patients without. The progression cohort had significantly more annual inpatient hospitalizations (non-IHD?=?1.32; IHD?=?1.40) than the non-progression cohort (non-IHD?=?0.36; IHD?=?0.34), and significantly more annual inpatient hospital days (non-IHD?=?13.07; IHD?=?13.52) than the non-progression cohort (non-IHD?=?2.29; with IHD?=?2.08). The progression cohort had over 3.5-times higher costs vs the non-progression cohort, independent of IHD (non-IHD?=?$12,798 vs $46,784; IHD?=?$12,582 vs $49,348).

Conclusion: Treating FMR patients earlier in their clinical trajectory may prevent disease progression and reduce high rates of healthcare utilization and expenditures.  相似文献

This article analyzes the quality of business structure from a macroeconomic perspective in the regional context. In addition to “traditional” variables such as innovation, internationalization, or entrepreneurial collaboration, new variables have been introduced: functional dependence and productive dependence. Two different economic territories have been chosen within the Spanish economy: the province of Barcelona (high relative income per capita) and the province of Seville (low relative income per capita). We find it is possible to distinguish two types of firms: a) “product-maker” firms (mainly located in advanced areas) and b) “market-maker” firms (mainly located in less developed areas).   相似文献

In this article, we employ a discrete choice experiment to examine preferences for functional dairy product attributes and willingness-to-pay estimates for consumers in Germany. We estimate preference heterogeneity by linking stated preference choice data not only to socioeconomic characteristics but also to attitudinal statements in a latent class framework. The empirical results indicate the existence of class-specific preference heterogeneity based on the consumers’ attitude towards functional foods, emphasizing the importance of attitudinal data in explaining consumers’ choice behavior. Our estimates demonstrate that within a class, consumers’ preferences are in accordance with their responses to attitudinal statements, that is functional food skeptics prefer non-functional dairy products, while functional food advocates have a negative preference for non-functional dairy products. The findings also show that all consumers place high value on dairy products enriched with known functional ingredients such as omega-3 fatty acids.  相似文献

The aim of this article is to discuss the feasibility of functional equivalence in idiom translations in Chinese-English cultures,trying to find efficient ways to avoid both under-translation and over-translation.The more functions are reproduced,the better the version will be at achieving correspondence between meaning and function.  相似文献
