中国主要粮食品种比较优势及进口市场结构研究

文章通过贸易专业化指数、结构优化指数等5个指标,对中国稻谷、小麦、玉米、大豆4个粮食品种的比较优势、进口市场结构变动程度及变动方向进行了分析。研究结果表明:我国稻谷比较优势逐年下降,玉米和大豆的比较劣势进一步凸显,小麦比较劣势明显但有所改善;4个粮食品种的进口来源高度集中,稻谷、玉米和大豆的进口市场结构不断优化,而小麦的进口市场结构则呈现出恶化趋势。值得注意的是,稻谷、玉米和大豆进口市场结构的优化过程较不稳定,且3个品种的进口市场结构还存在较大的优化空间。同时,玉米进口市场结构在近五年已由优化趋势转为劣化趋势。

沈德符史学思想探析——基于《万历野获编》的史料记载

《万历野获编》堪称明代历史琐闻类笔记中的翘楚,因内容丰富广博、考证切实,为历代史家所重。以往的研究集中于该笔记的史料、艺术、文学价值,却未有学者对作者沈德符蕴藏于书中的史学思想予以足够重视。扎根于《万历野获编》的史料记载,结合晚明私史勃兴与实学思潮盛行的背景,从多方面综合考察作者的治史理念与准则,不仅有助于剖析沈德符史学思想的核心内容,对后世学者正确理解、运用《万历野获编》也不无裨益。     

Personalized goal-based investing via multi-stage stochastic goal programming

In this paper, we propose a goal-based investment model that is suitable for personalized wealth management. The model only requires a few intuitive inputs such as size of wealth, investment amount, and consumption goals from individual investors. In particular, a priority level can be assigned to each consumption goal and the model provides a holistic solution based on a sequential approach starting with the highest priority. This allows strict prioritization by maximizing the probability of achieving higher priority goals that are not affected by goals with lower priorities. Furthermore, the proposed model is formulated as a linear program that efficiently finds the optimal financial plan. With its simplicity, flexibility, and computational efficiency, the proposed goal-based investment model provides a new framework for automated investment management services.     

Major bleeding risk and healthcare economic outcomes of non-valvular atrial fibrillation patients newly-initiated with oral anticoagulant therapy in the real-world setting

Aims: This study compared the risk for major bleeding (MB) and healthcare economic outcomes of patients with non-valvular atrial fibrillation (NVAF) after initiating treatment with apixaban vs rivaroxaban, dabigatran, or warfarin.

Methods: NVAF patients who initiated apixaban, rivaroxaban, dabigatran, or warfarin were identified from the IMS Pharmetrics Plus database (January 1, 2013–September 30, 2015). Propensity score matching (PSM) was used to balance differences in patient characteristics between study cohorts: patients treated with apixaban vs rivaroxaban, apixaban vs dabigatran, and apixaban vs warfarin. Risk of hospitalization and healthcare costs (all-cause and MB-related) were compared between matched cohorts during the follow-up.

Results: During the follow-up, risks for all-cause (hazard ratio [HR]?=?1.44, 95% confidence interval [CI]?=?1.2–1.7) and MB-related (HR?=?1.57, 95% CI?=?1.0–2.4) hospitalizations were significantly greater for patients treated with rivaroxaban vs apixaban. Adjusted total all-cause healthcare costs were significantly lower for patients treated with apixaban vs rivaroxaban ($3,950 vs $4,333 per patient per month [PPPM], p?=?.002) and MB-related medical costs were not statistically significantly different ($100 vs $233 PPPM, p?=?.096). Risk for all-cause hospitalization (HR?=?1.98, 95% CI?=?1.6–2.4) was significantly greater for patients treated with dabigatran vs apixaban, although total all-cause healthcare costs were not statistically different. Risks for all-cause (HR?=?2.22, 95% CI?=?1.9–2.5) and MB-related (HR?=?2.05, 95% CI?=?1.4–3.0) hospitalizations were significantly greater for patients treated with warfarin vs apixaban. Total all-cause healthcare costs ($3,919 vs $4,177 PPPM, p?=?.025) and MB-related medical costs ($96 vs $212 PPPM, p?=?.026) were significantly lower for patients treated with apixaban vs warfarin.

Limitations: This retrospective database analysis does not establish causation.

Conclusions: In the real-world setting, compared with rivaroxaban and warfarin, apixaban is associated with reduced risk of hospitalization and lower healthcare costs. Compared with dabigatran, apixaban is associated with lower risk of hospitalizations.     

浅析生活方式变迁下的居住诉求与房地产广告——以《海峡都市报》为例

1998年,国务院宣布取消＂福利分房＂,把住宅变成商品推向市场,房地产开始作为一个独特的行业迅速成长和发展起来。在此期间,福州生活方式的变迁成为影响当地人们购房的重要因素之一。为了追求利益的最大化,房地产商们必然要充分考虑到可能影响消费者购房的生活方式。其中,私密性、怀旧性、健康生活观、温泉四大诉求成为福州1997～2007房地产广告策划发生变化的重要驱动。     

基于风险维度的货币政策传导非对称性研究

现有文献货币政策传导非对称性的研究主要集中于产出维度,文章从风险维度研究不同货币环境下货币政策对微观企业风险传导的非对称性,结果表明:宽松货币环境强化了货币政策风险传导的微观效应,而紧缩货币环境削弱了货币政策风险传导的微观效应。虽然存款准备金率对企业的风险传导效应小于利率,但是在不同货币环境下存款准备金率对企业风险传导的非对称性却强于利率。因此央行在制定货币政策时须根据不同货币环境下微观主体对货币政策的风险敏感度的差异选择合理的货币政策工具及其组合搭配,以免企业在宽松货币环境下的过度风险承担。
