固定资产投资、技术创新增量和对外出口对我国经济增长的影响——基于35个大型城市面板数据的实证研究

利用面板数据回归分析方法,研究了我国35个大型城市固定资产投资、技术创新增量以及对外出口对经济增长的影响;引入了发明专利当量的概念,研究发现：3个因素对经济增长均为正向影响,且固定资产投资和对外出口是大型城市经济增长的主要驱动因素,技术创新增量对经济增长的贡献率较低;固定资产投资和技术创新增量均存在滞后效应。     

行业特征与技术创新绩效的实证研究——基于数据包络分析的广东工业行业面板数据分析

文章运用数据包络分析（DEA）方法对广东工业35个行业1997—2008年的全要素生产率（TFP）中的技术效率和前沿技术进步进行测算,并结合竞争程度、企业规模、资本密集度、产权结构情况四个行业特征指标,利用固定效应面板数据模型对行业特征和创新绩效差异进行实证分析。分析结果表明,市场竞争程度越高、资本密集度较低有利于技术效率和全要素生产率的提高;企业规模较大和资本密集度较高则有助于前沿技术进步的提升;而产权结构不是影响企业创新绩效的关键因素。     

安徽经济增长的人力资本存量效应分析

首先从理论上分析了人力资本存量对经济增长的要素效应,并以安徽省17个地级市为研究对象,通过2000-2006年的面板数据建立生产函数,实证研究了安徽省各市人力资本在地区经济增长中的贡献率.实证结果表明:人力资本存量在C-D函数中的要素效应高于物质资本存量的要素效应,人力资本对物质资本的互补弹性大大高于物质资本对人力资本的互补弹性.     

基于全要素生产率和DEA的勘察设计行业效率评价

文章对中国31个省市自治区2006--2011年工程勘察设计行业投入产出面板数据,采用非参数的Malmquist—DEA方法测定各省市行业全要素生产效率及其变化。结果表明,在空间上,东部地区行业全要素生产效率平均水平高于中部,中部高于西部;在时间上,行业全要素生产效率随国家经济发展状况和政策调整波动较大。因此,要提高行业的全要素生产率,除需行业规模效率的提高外,更重要的是加大对技术进步的支持力度和纯效率的提高。     

Peter Schmidt: Econometrician and consummate professional

Peter Schmidt has been one of its best-known and most respected econometricians in the profession for four decades. He has brought his talents to many scholarly outlets and societies, and has played a foundational and constructive role in the development of the field of econometrics. Peter Schmidt has also served and led the development of Econometric Reviews since its inception in 1982. His judgment has always been fair, informed, clear, decisive, and constructive. Respect for ideas and scholarship of others, young and old, is second nature to him. This is the best of traits, and Peter serves as an uncommon example to us all. The seventeen articles that make up this Econometric Reviews Special Issue in Honor of Peter Schmidt represent the work of fifty of the very best econometricians in our profession. They honor Professor Schmidt's lifelong accomplishments by providing fundamental research work that reflects many of the broad research themes that have distinguished his long and productive career. These include time series econometrics, panel data econometrics, and stochastic frontier production analysis.     

Has the Lewis Turning Point Arrived in China?—Theoretical Analysis and International Experience

各国农业劳动力占总劳动力的比重随着各国人均GDP增长呈现先加速下降而后减 速下降的趋势, 分界点就是刘易斯转折点。跨国平行数据的回归结果表明, 刘易斯转 折点在人均GDP为3,000-4,000美元 (购买力平价2000年国际美元) 之间出现。中国的 人均GDP超越了这一水平, 但农业劳动力比重远高于该经济发展水平下的世界平均水 平, 这很可能意味着中国的农业劳动力转移仍有较大潜力。

关键词: 刘易斯转折点 劳动力转移 跨国平行数据

Using World Bank cross-country panel data to estimate the economic development level that corresponds to the Lewis turning point, we find that as GDP per capita increases, the share of rural labor in the total labor force tends to decrease first at an accelerated rate and then, after passing the Lewis turning point, at a reduced rate. Regression analysis of cross- country panel data shows that the Lewis turning point is reached when GDP per capita reaches somewhere between US$3,000 and US$4,000 dollars (PPP, constant international US dollars for the year 2000). GDP per capita in China has exceeded this level, but the proportion of rural labor in the total labor force remains much higher than the average for countries at the same level of economic development. This may imply that there is still considerable potential for rural labor transfer in China.     

Girlz II women: Age‐grading,language change and stylistic variation

Informed by abstract models of language change or stability over time, we present a longitudinal study of two African American females, first interviewed as teenagers, and re‐recorded twenty years later. As teenagers, they used morpho‐syntactic features of AAVE voraciously. But as working adults, these women distance themselves from their teenage activities and social networks, and display a considerably reduced vernacular usage that accords with their articulated concern to get ahead. The diachronic interpretation that best characterizes their transformation is age‐grading rather than generational change, since change at the individual level is accompanied by stability at the community level. The picture is complicated by intermediate recordings showing that one of the speakers is a stylistic chameleon, capable since her teenage years of varying copula absence rates depending on addressee, topic, and projected persona. But the age‐grading interpretation of change at the individual level remains valid based on the evidence of her reduced use of habitual be2, and third singular present tense –s absence. The case highlights the importance of paying more attention to stylistic variation and including more than two time points in sociolinguistic studies of change in real and apparent time.     

Response predictions in regressions on panel data

In this paper we consider the problem of obtaining best linear unbiased estimators of individual response coefficients in a Random Coefficient Linear Regression (RCR} Model, comparing alternative estimators for these response vectors through a simulation study. We also provide an empirical example that illustrates the estimation procedure proposed here.     

Kumulation von Mikrodaten – Konzeptionelle Grundlagen und ein Vorschlag zur Realisierung

Zusammenfassung: In dieser Studie wird ein Konzept zur Kumulation von laufenden Haushaltsbudgetbefragungen im Rahmen des Projektes Amtliche Statistik und sozioökonomische Fragestellungen entwickelt und zur Diskussion gestellt. Dafür werden die theoretischen Grundlagen und Bausteine gelegt und die zentrale Aufgabe einer strukturellen demographischen Gewichtung mit einem Hochrechnungs–/Kalibrierungsansatz auf informationstheoretischer Basis gelöst.Vor dem Hintergrund der Wirtschaftsrechnungen des Statistischen Bundesamtes (Lfd. Wirtschaftsrechnungen und EVS) wird darauf aufbauend ein konkretes Konzept für die Kumulation von jährlichen Haushaltsbudgetbefragungen vorgeschlagen. Damit kann das Ziel einer Kumulation von Querschnitten mit einer umfassenderen Kumulationsstichprobe für tief gegliederte Analysen erreicht werden. Folgen sollen die Simulationsrechnungen zur Evaluation des Konzepts.

Summary: In this study a concept for cumulating periodic household surveys within the frame of the project Official Statistics and Socio–Economic Questions is developed and asks for discussion. We develop the theoretical background and solve the central task of a structural demographic weighting/calibration based on an information theoretical approach.Based on the household budget surveys of the Federal Statistical Office (Periodic Household Budget Surveys and Income and Consumption Sample (EVS)) a practical concept is proposed to cumulate yearly household surveys. This allows a cumulation of cross–sections by a comprehensive cumulated sample for deeply structured analyses. In a following study this concept shall be evaluated.
