财政分权与义务教育财政管理体制问题探析

我国是成功实施财政分权化的国家之一。作为公共财政框架部分之一的义务教育也实行了分权化管理,义务教育办学的责任主要地落在了县、乡两级地方政府身上。而我国庞大的义务教育事业由县、乡甚至村脆弱的财力来承担,可谓“杯水车薪”：一些农村地区和贫困山区学龄儿童无学可上,无书可读等现象屡见不鲜。可见过度分权化的义务教育财政管理体制是制约当今中国义务教育发展的症结所在。

区域产业结构与就业结构的比较及启示——基于重庆市万州区和涪陵区的分析

产业结构和就业结构的变化反映出区域经济发展的资源分配结构及其发展进程和水平.分析发现,万州区与涪陵区在产业结构上都存在第一产业所占比重与其吸纳劳动力的比重不一致的现象,其中,涪陵区第二产业比重较大但吸纳劳动力能力较弱,而万州区第三产业吸纳劳动力能力要弱于涪陵区.两地应大力发展第三产业以改善就业结构,充分吸纳从第一产业转移出来的劳动力.     

践行工匠精神 打造土木建筑行业高素质人才队伍

培养德艺兼备的建筑工匠人才是推动建筑企业发展的必然举措。基于新时代我国建筑行业人才爱岗敬业精神缺失、技术专业能力不强的问题,建筑人才培养必须以工匠精神为指引,打造爱岗敬业、专业能力突出的高素质土木建筑人才。论文以工匠精神的内涵概述作为切入点,分析培育具有工匠精神的建筑人才的价值和意义,最后提出践行工匠精神,培养高素质建筑人才的路径对策。     

Earnings management by firms announcing earnings after SEC filing

This study examines motivation and stock market reactions of firms announcing earnings in the Wall Street Journal (WSJ) after filing with the Security Exchange Commission (SEC). Most firms announce earnings in the WSJ before SEC filing. Firms that reverse this sequence are voluntarily delaying public earnings announcements. The authors find that these firms are not only poor financial performers but also engage in earnings managements. They are delaying their WSJ announcements to postpone announcing bad news. The authors find significant stock price reactions to both the SEC filing and the WSJ announcement. The price reaction to earnings is incomplete at the SEC filings. The market continues reacting to firms' subsequent WSJ announcements as if the SEC filing fails to communicate earnings information to some investors.     

岩溶山地土地整理模式研究

西南岩溶山地是典型的脆弱生态环境,与经济发达地区相比,有其自身的土地资源特点、生态特点和社会特点。文章以此为基础,提出岩溶山地土地整理的原则、思路,认为岩溶山地的土地整理应从高标准基本农田建设、阶梯式还林退耕和辐射式生态重建、实行土地双轨制、直接对农户投资着手等,提出不同空间尺度如县市、乡镇、村组、农户土地整理的具体模式。非耕地资源开发是岩溶山地土地整理的重点。     

Nonlinear IV unit root tests in panels with cross-sectional dependency

We propose a unit root test for panels with cross-sectional dependency. We allow general dependency structure among the innovations that generate data for each of the cross-sectional units. Each unit may have different sample size, and therefore unbalanced panels are also permitted in our framework. Yet, the test is asymptotically normal, and does not require any tabulation of the critical values. Our test is based on nonlinear IV estimation of the usual augmented Dickey–Fuller type regression for each cross-sectional unit, using as instruments nonlinear transformations of the lagged levels. The actual test statistic is simply defined as a standardized sum of individual IV t-ratios. We show in the paper that such a standardized sum of individual IV t-ratios has limit normal distribution as long as the panels have large individual time series observations and are asymptotically balanced in a very weak sense. We may have the number of cross-sectional units arbitrarily small or large. In particular, the usual sequential asymptotics, upon which most of the available asymptotic theories for panel unit root models heavily rely, are not required. Finite sample performance of our test is examined via a set of simulations, and compared with those of other commonly used panel unit root tests. Our test generally performs better than the existing tests in terms of both finite sample sizes and powers. We apply our nonlinear IV method to test for the purchasing power parity hypothesis in panels.
