论深化国有企业改革

面对国内外市场上日益强大的竞争力,传统国有企业不同程度地陷入困境,深化国有企业改革已经迫在眉睫,对此要有生死存亡的紧迫感。深化国有企业改革的主要任务是在国有企业结构调整和转换企业经营机制方面尽快取得突破性进展,最终实现国有企业持续保持支柱地位、产业竞争力乃至国家竞争力得以不断提高的战略目标。     

Structural adjustment and family policy in Africa: Lessons from Sudan

The economic strategy pursued by a country profoundly influences the well-being of families. This article uses a social accounting model of the Sudanese economy to compare the effects of two alternative development strategies on growth, employment, and income distribution. The first strategy considered is a conventional growth-oriented strategy emphasizing irrigated, export-oriented agriculture and modern, capital-intensive industry; the second one is a traditional agriculture-led development (TALD) strategy focused on enhancing equity and improving family nutrition by expanding food production. The study's findings for Sudan demonstrate that there is no necessary trade-off between growth and equity. The TALD strategy fosters income growth for the most vulnerable families while simultaneously maximizing aggregate growth. It also holds the prospect of enhancing family equity and increasing access to traditional institutions that provide support to families.World BankHer research interests encompass issues related to poverty and inequality in developing countries.

影响短语成立的重要因素

讨论短语是否成立的问题并总结出一些规律。我们发现语义、结构层次和韵律是影响短语成立的重要因素。语义特征从多方面影响短语的成立,是最主要因素。结构层次和韵律也在某种程度上影响了短语的成立。     

北京市物流业融合发展的低碳效应--基于全产业链的SDA分解技术

运用投入产出分解技术推导物流业贡献值完耗表及影子技术经济矩阵,测算全产业链下物流业融合系数,比较分析19952010年北京市物流业融合发展状况及结构减排潜力。研究结果表明：北京市物流业产业融合度普遍高于全国平均水平,若物流业与物流业自身、制造业等行业融合度上升1％,可促使北京市碳排放强度下降0．08和0．06个百分点。为科学评价我国物流业发展水平及产业地位提供了新思路,为促进北京市产业结构的低碳升级提供一定的支持。

民族地区农村大学生就业竞争力影响因素分析

近年来,农村大学生在校人数增长迅速,其就业问题也就成为社会和高校关注的重点问题。以民族地区广西民族大学农村大学生为调查对象,通过问卷调查获取第一手资料数据,利用结构方程模型及AMOS软件建立SEM模型,分别从个体因素、学校因素、家庭因素三个方面探讨其对就业竞争力的影响程度,指出家庭因素与个人因素对农村大学生就业竞争力的影响程度较大,而学校因素对农村大学生就业竞争力的影响也同样不可忽视。研究旨在为农村大学生做好职业规划,找到合适的工作岗位提供参考和借鉴。     

Assessing the treatment effect in a randomized controlled trial with extensive non‐adherence: the EVOLVE trial

Intention‐to‐treat (ITT) analysis is widely used to establish efficacy in randomized clinical trials. However, in a long‐term outcomes study where non‐adherence to study drug is substantial, the on‐treatment effect of the study drug may be underestimated using the ITT analysis. The analyses presented herein are from the EVOLVE trial, a double‐blind, placebo‐controlled, event‐driven cardiovascular outcomes study conducted to assess whether a treatment regimen including cinacalcet compared with placebo in addition to other conventional therapies reduces the risk of mortality and major cardiovascular events in patients receiving hemodialysis with secondary hyperparathyroidism. Pre‐specified sensitivity analyses were performed to assess the impact of non‐adherence on the estimated effect of cinacalcet. These analyses included lag‐censoring, inverse probability of censoring weights (IPCW), rank preserving structural failure time model (RPSFTM) and iterative parameter estimation (IPE). The relative hazard (cinacalcet versus placebo) of mortality and major cardiovascular events was 0.93 (95% confidence interval 0.85, 1.02) using the ITT analysis; 0.85 (0.76, 0.95) using lag‐censoring analysis; 0.81 (0.70, 0.92) using IPCW; 0.85 (0.66, 1.04) using RPSFTM and 0.85 (0.75, 0.96) using IPE. These analyses, while not providing definitive evidence, suggest that the intervention may have an effect while subjects are receiving treatment. The ITT method remains the established method to evaluate efficacy of a new treatment; however, additional analyses should be considered to assess the on‐treatment effect when substantial non‐adherence to study drug is expected or observed.

劳动力结构与产业结构调整

根据家庭不变量信息将“城镇住户调查数据”匹配成长时期的个体层面面板数据后发现,不同产业的劳动者构成存在明显差异。统计结果证实,劳动者在产业间的转移概率与个体特征有关。理论模型进而说明,劳动者在产业间的转移决策是个体特征的函数,并可通过multinomial logit模型估计。实证结论表明,性别和受教育程度是劳动者产业间转移的关键影响因素,当前工作性质还将影响已参加工作劳动者的转移决策,产业结构调整也将在需求面和供给面上引导劳动者在产业间转移。以上结论在更细致的行业层面上和不同时期内具有稳健性。对中国经济结构转型进行微观考察有助于为制定与劳动力结构相匹配的产业政策和选择不同的产业结构调整驱动力提供参考。
