基于SSM的区域产业结构分析——以环渤海16市为例

本文以2005年至2008年这四年作为考察期,利用计量地理学中的SSM(偏离—份额分析法),分析了环渤海经济区中的十六个沿海城市在产业结构与区位竞争力方面的优势与劣势,并根据产业结构偏离分量与区位偏离分量的组合情况,对各个城市的经济增长状况进行了定位,有助于它们调整各自的产业结构,缩小城市间经济差异,使环渤海经济区的经...     

河北粮食生产可持续发展策略研究

河北粮食生产主要受到社会重大变革、政策调整、农业生产条件、农资投入、科技进步、价格变动等因素的综合影响,单产比播种面积对总产的影响更大。分析了河北省粮食生产发展的制约因素:耕地减少、水资源短缺和成本、效益限制。分析粮食增产潜力,文章认为应以农用水资源为主的农业生产条件合理确定河北省粮食生产品种结构与布局以及粮食产量目标。提出应在基本粮田保护区设立、中低产田、水利建设与节水、优良品种及农业科技等方面着力加强。同时在耕地流转、政府投入、种粮补贴等方面也应配套政策措施。     

河北省京津风沙源区生态经济社会发展水平评价研究

本研究采用层次分析法,对2000年和2008年河北省京津风沙源区21个县的生态、经济和社会发展水平进行定量评价分析。从分析结果来看,河北省京津风沙源区生态、经济、社会发展水平整体上呈上升趋势,但发展水平还不高,各县之间差距较大;生态环境整体恶化的趋势逐步变缓、局部生态环境明显好转,该区生态建设进入了治理大于破坏的阶段;协调发展能力有了较大提高,经济发展的速度明显快于生态和社会的发展速度。     

主体功能区战略下重点林区产业结构优化策略分析

以我国重点林区中内蒙古、黑龙江、四川、云南四省为研究对象,通过对研究对象进行主体功能区定位确定其发展要点,选取碳排放强度指标进行分析,证实其发展政策的合理性并直观、有力地说明产业结构调整所带来的生态、经济效益的影响,进而将该影响数据化得出碳排放强度的产业结构弹性以估算产业结构调整的减碳效应,结合分析结果提出符合主体功能区定位的相关产业建议,以实现重点林区的产业结构优化。     

试论土地督察类型区的划分

为探索解决西北地区幅员辽阔、经济发展不平衡、土地利用区域差异较大而土地督察机构人员不多的矛盾,以青海省为例,确定土地督察类型区的划分原则、方法、指标选取和数据处理方式.按照地域分异规律,采用系统聚类法和定性修正法将青海省划分为耕地保护、城市发展、矿业发展、生态保护等四大土地督察监管类型区,分析指明各类型区的功能定位、土地利用和违法特点,为评定土地督察级别,有针对性地制定差别化的分区督察办法,创新土地督察方式方法,提高土地督察的效率和效果,有效实现土地督察目标提供依据.     

浅析辽西城市群发展模式

本文从区域经济的视角,结合辽西城市群的基本情况,对照三种主要的城市群发展模式,对辽西城市群发展模式的选择进行了较为深入的剖析。希望通过本文的研究,对辽西城市群发展模式的决策选择提供一定的借鉴价值。     

Drivers and barriers to the adoption and diffusion of Sustainable Jet Fuel (SJF) in the U.S. Pacific Northwest

Sustainable Jet Fuel (SJF) represents an important component of the airline industry's strategy to simultaneously reduce GHG emissions while meeting a growing demand for international air travel. SJFs also have the potential to provide fuel supply diversification and security, enhance fuel price stability and provide regional/rural economic development benefits. This paper measures and ranks perceived drivers and barriers to an economically viable SJF industry in a unique U.S. region, the U.S. Pacific Northwest (PNW), through personal interviews with key aviation fuel supply chain stakeholders conducted from June to September 2015. In addition to providing a fertile arena for this first effort to systematically assess these drivers and barriers, the U.S. PNW is unique due to the region's long strategic focus on aviation innovation and its importance to the regional economy, the seminal efforts in the region to outline a path forward on SJF beginning in 2010, and the relatively small population spread over a large geographic area with a limited number of “hub” airport nodes which geographically concentrates aviation fuel demand and distribution. Nineteen stakeholder interviewees acknowledge that, in order for regional SJF adoption-diffusion to occur, airline jet fuel buyers must drive the process, particularly as they deal with greenhouse gas (GHG) emission issues and related policy considerations. Important perceived barriers to SJF industry scale-up in the U.S. PNW include the high production costs of SJF and related issues, such as fuel logistics and quality control in the transport, storage, and blending of SJFs. Perceptions around chain-of-custody issues, such as blending, tracking, and crediting of SJFs and future SJF market share projections for the year 2030 were also examined. Incorporating stakeholder input into discussions about adding blended SJF into the U.S. aviation fuel supply provides needed insight for the biofuels industry, policymakers, and researchers.     

Foreign ownership mode,executive compensation structure,and corporate governance: Has the literature missed an important link? Evidence from Taiwanese firms

We propose an alternate context-based extension to the agency theory-grounded explanation of foreign ownership mode choices proposed in the literature. Using a sample of Taiwanese firms investing in the greater China region over the 2001–2009 period, we show that both economic and non-economic factors influence the choice of foreign ownership mode. In addition, we document that higher institutional ownership percentages motivate Taiwanese firms to select shared ownership in the greater China region. Further, no long term compensation mix/ownership structure link is found. These findings run counter to a theory provided for foreign ownership mode choices of US based firms. Our findings provide support for the validity of stewardship and social capital theory, but not financial incentives-based agency theory, for Taiwanese firms investing in the greater China region.     

袁州政区变迁考论——兼对部分史籍相关记载的校勘

袁州作为地方行政单位始于隋开皇十一年（591）,至1912年被裁撤,其名称、隶属、治所和版图均少有变迁,体现出较强的稳定性。这主要是由于袁州的地理位置与外界往来较少造成的。今日宜春市的行政区划存在一定的不合理性,影响到了行政效率和行政区划的稳定性。中华书局点校本《元史》、《明史》、《元和郡县图志》和《读史方舆纪要》等史籍对古代袁州行政沿革的记载存在一些错误,逐一勘之。
