粤港澳大湾区城市建设用地和经济规模增长格局演变及协同关系

文章研究了1990—2017年期间粤港澳大湾区各城市建设用地增长情况及经济规模变化情况,并对二者之间的协同关系进行了分析。主要结论如下:1990—2017年,粤港澳大湾区各城市建设用地增长速度总体呈加快态势,各城市在不同时期建设用地增长速度的变化与城市所处发展阶段的变化密切相关。大湾区内城市经济规模多数在广东—港澳范围内排行前列,且位序逐渐攀升,仅有肇庆和澳门在1990—2017年经济规模在广东—港澳范围内排序明显下降。以1990年为基期,至2017年,大湾区整体建设用地与经济规模增长的协同度一直处于上升的态势,有序性不断增强,上升速度2010—2017年期间与之前相比有明显的下降,体现出近年来随着城市化进程的不断推进,建设用地增长和经济规模增长二者之间的相互依赖程度有所下降。各城市间建设用地与经济规模增长的协同度演变差异性十分明显。深圳、珠海、中山三个城市建设用地增长对经济规模增长的作用效率在研究期间不断上升,其他多数城市研究期间该效率在2000—2010年期间达到最高,2010—2017年期间均出现明显下降。各城市间产业的发展阶段以及目标定位的不同造成了建设用地和经济规模增长协同性...     

农村土地集体所有制对劳资关系形成的积极影响及启示

农村土地集体所有制作为一种"普照的光",使中国劳资关系形成跨越了残酷的原始积累阶段,避免了劳资关系发展初期易发的尖锐冲突,使中国劳资关系伴随着工业化城市化进程协调发展。社会主义公有制不仅需要而且可以与市场经济相结合,并使市场经济的作用得到有益发挥。必须坚定不移走社会主义道路,积极发挥社会主义基本制度的优势,更好更快地推进中国现代化进程,实现中华民族伟大复兴。     

Land,Gender, and Food Security

Since 2008, a surge in large-scale land acquisitions, or land grabs, has been taking place in low- and middle-income countries around the globe. This contribution examines the gendered effects of and responses to these deals, drawing on nine studies, which include conceptual framing essays that bring in debates about human rights, studies that draw on previous waves of land acquisitions globally, and case studies that examine the gendered dimensions of land dispossession and loss of common property. Three key insights emerge: the evolving gender and land tenure literature provides valuable information for understanding the likely effects of land deals; some of the land deal issues transcend gender-equity concerns and relate to broader problems of dispossession and loss of livelihoods; and huge gaps remain in our knowledge of gender and land rights that require urgent attention and systematic integration of gender analysis into mainstream research.

Overall survival,costs, and healthcare resource use by line of therapy in Medicare patients with newly diagnosed metastatic urothelial carcinoma

Aims: Medicare patients with metastatic or surgically unresectable urothelial carcinoma (mUC) often receive platinum-based chemotherapy as first line of therapy (LOT), but invariably progress, requiring additional LOTs and healthcare resource use (HCRU). To better understand the evolving mUC treatment landscape, the economic burden of chemotherapy-based mUC treatments among US Medicare patients was estimated.

Methods: Newly diagnosed Medicare patients with mUC were identified from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. Patients were followed from diagnosis to death, disenrollment, or end of study to characterize LOTs (first [LOT1], second [LOT2], and third or greater [LOT3+]). Kaplan-Meier methods were used to estimate overall survival (OS) by LOT. HCRU and mean costs were reported over the follow-up period, LOT duration, and maximum LOT received.

Results: Among 1,873 eligible patients with mUC (median age?=?77?years; median follow-up?=?7.5?months), 1,035 (55%) received no chemotherapy. Among chemotherapy-treated patients, 61% had LOT1 only, 25% had LOT1 and LOT2 only, and 14% had LOT3+. Median OS was 8.1?months, range was 4.3 (untreated) to 29.8 (LOT3+) months. HCRU frequency increased with additional LOTs. Mean cumulative per-patient cost was $82,912 for all patients, increasing with additional LOTs (untreated?=?$57,207; LOT1?=?$99,213; LOT2?=?$125,190; LOT3+?=?$163,884). Mean per patient per month cost was $18,827 for all patients, decreasing with increasing number of LOTs received (untreated?=?$27,211; LOT1?=?$9,601; LOT2?=?$7,325; LOT3+?=?$6,017).

Limitations: Potential for treatment misclassification when using the algorithm defining LOTs and non-generalizability of results to younger patients.

Conclusions: Over 50% of Medicare patients with mUC received no chemotherapy. Among chemotherapy-treated patients, most received only one LOT. Additional LOTs led to higher mean costs and HCRU, but as patients were followed longer, monthly costs decreased. As treatments evolve to include immuno-oncology agents, these findings provide a clinically relevant economic benchmark for mUC treatment across different traditional LOTs.
