"双评价"(资源环境承载能力评价和国土空间开发适宜性评价)作为构建国土空间基本战略格局的科学基础尚未延伸至海洋层面。海域"双评价"作为沿海地区国土空间规划工作的重要内容,存在理论缺失、技术方法不完善等问题。文章以海域功能理论为基础,从人类海洋活动出发,探索海域"双评价"的实践方案,建立"双评价"到海域利用优化的科学逻辑,指出基于"双评价"的海域利用冲突识别是海洋空间规划的关键。以温州市海域为例,基于本底资源从空间、渔业、环境和生态四方面进行单要素承载力测算,以此获得海域综合承载力作为监测预警的标志。选择渔业用海和建设用海两类典型用海进行适宜性分析,确定海洋空间利用的最优布局,判断海域利用空间冲突。结果表明:温州市沿海区县的海洋承载能力差异较大,资源环境分化严重,龙湾区与洞头区渔业资源开发超载;乐清市与龙湾区的海洋环境超载。渔业用海适宜面积占比较低且分布于远海地带。不适宜区域集中于瓯江、飞云江、鳌江三江入海口岸海域。建设用海适宜区域集中于近岸海域,远海区域距离城镇与交通较远,自然条件中水深较深,成本较高。苍南县和平阳县海域利用冲突较少,用海布局合理。乐清市、龙湾区与洞头区存在显著冲突。"双评价"的实践与应用是指导沿海地区海洋经济发展与海洋资源保护的关键,能够综合识别海洋利用的冲突,有助于沿海地区海洋空间规划。 相似文献

近年来我国利率市场化改革积极推进,实体经济发展积极向创新驱动转型,一个亟须研究厘清的关键问题是,银行业竞争如何驱动企业创新活动?本文关注银行价格竞争对企业创新的影响,以2013—2018年沪深两市的上市企业为样本,采用“中介效应”因果分析模型,实证检验了银行价格竞争对企业研发投资的影响,并识别出以融资约束为中介渠道的作用机制。研究发现,银行价格竞争不仅会提高银行的风险容忍度,直接增加R&D投资的信贷供给意愿,而且还会通过降低贷款价格和增加贷款可得性来缓解企业整体的融资约束,间接促进企业创新活动。这一机制在解除贷款利率管制之后以及在民营企业层面体现得更加明显。本文的研究结果对于深化金融市场化改革、改善金融服务实体经济效果以及实施经济创新驱动发展战略,具有明确的政策启示。 相似文献

Using an extensive global sample, this paper investigates the impact of the term structure of interest rates on bank equity returns. Decomposing the yield curve to its three constituents (level, slope and curvature), the paper evaluates the time‐varying sensitivity of the bank's equity returns to these constituents by using a diagonal dynamic conditional correlation multivariate GARCH framework. Evidence reveals that the empirical proxies for the three factors explain the variations in equity returns above and beyond the market‐wide effect. More specifically, shocks to the long‐term (level) and short‐term (slope) factors have a statistically significant impact on equity returns, while those on the medium‐term (curvature) factor are less clear‐cut. Bank size plays an important role in the sense that exposures are higher for SIFIs and large banks compared to medium and small banks. Moreover, banks exhibit greater sensitivities to all risk factors during the crisis and post‐crisis periods compared to the pre‐crisis period; though these sensitivities do not differ for market‐oriented and bank‐oriented financial systems. 相似文献

This paper studies the equilibrium determinacy properties of a simple interest rate rule in a small open economy subject to currency substitution (i.e., the use of a foreign currency for domestic transactions) and risk premia on foreign borrowing. It shows that if currencies are substitute in the provision of liquidity services the rule׳s response to inflation has to be sufficiently above unity for the equilibrium to be locally determinate. This reinforced Taylor principle requirement appears to be more binding in economies characterized by a larger elasticity of currency substitution, more debt-elastic country risk premia, and intermediate degrees of dollarization in transactions. 相似文献

I examine the impact of usury laws on the Peruvian credit market between 1825 and 1852. Using a new data set of nearly 2,000 loans from archival sources, I show that the repeal of colonial anti-usury laws in early 1833 had an important effect on the allocation of credit in Lima. It increased interest rates and promoted access to credit. Furthermore, lenders made loans with greater maturities after the repeal of usury laws. 相似文献

In this paper we investigate how the evolution of income growth, real interest rates, and inflation have driven income inequality across a variety of countries with particular focus on the BRICS economies (Brazil, Russia, India, China, and South Africa) during the period 2001 to 2015. Our work suggests that, when central banks of the BRICS economies use monetary policy for macroeconomic stabilization, they need to consider the impact monetary policy changes have on the distribution of income in their nations. Our estimates reveal that the unintended consequence of policies that induce economic growth and higher prices is higher income inequality. We find that the positive relationship between the three macroeconomic variables and income inequality for the BRICS economies is stronger during the post-2008 period. 相似文献

We study a bilateral negotiation set-up where, at a bargaining impasse, the disadvantaged party chooses whether to escalate the conflict or not. Escalation is costly for both parties, and it results in a random draw of the winner of the escalated conflict. We derive the behavioral predictions of a simple social utility function, which is convex in disadvantageous inequality, thus connecting the inequity aversion and the prospect theory models. Our causal laboratory evidence is, to a large extent, consistent with the predicted effects. Among other things, the model predicts that the escalation rate is higher when escalation outcomes are riskier, and that the disagreement rate is lower when the cost of escalating the conflict is higher. 相似文献

The conservation and management of protected areas in urban settings has become increasingly challenging with dynamics over land use change in adjacent urban areas being highly relevant to, but at times conflicting with, the protected area. This study seeks to better understand the implications of land use change processes to urban protected area management through the case study of the Las Piñas – Parañaque Critical Habitat and Ecotourism Area (LPPCHEA) in Metro Manila, Philippines. Factors and processes influencing land use change and protected area management and the impact of stakeholders’ perceptions on protected area were analyzed. The urban protected area in itself has limited influence on its surrounding urban areas, as land use change in these areas is shaped more by social, economic and policy/institutional factors occurring within the context of urban-regional development. The study also found that land use conflict is evident in an urban protected area due to the competing ecosystem services derived by various stakeholders. This discord is deepened by the lack of coordination between land use planning and protected area management. Integrating protected area management with land use planning through legally binding instruments, specific timeframes and clear internal procedures can help resolve land use conflict for an urban protected area at the strategic or policy level. 相似文献

The use of debt is prevalent in the restaurant industry. While there have been numerous studies on restaurant capital structure, this study examines the relationship between firm performance and effective interest rate on debt used by restaurant firms. This study uses a sample of 56 publicly traded U.S. restaurant firms for the years 2012–2014. We examine the relationship between effective interest rates and firm performance as measured by approximate Tobin’s Q, return on assets, and return on equity. We find a significant and positive relationship between effective interest rates and return on equity. 相似文献
