中美日三国经济增长质量比较:基于技术进步的角度

本文通过构造一个包含资本质量的柯布-道格拉斯形式的总量生产函数,对中美日三国1980—2007年的经济增长质量进行了详细的分析。分析结果表明,在整个考察期内,不同要素对于不同国家的经济发展所发挥的作用是不同的。但是,从总体上来看,全要素生产率的发展在三个国家的经济发展过程中均占据了非常重要的地位。同时,体现在资本质量上的技术进步对于不同国家则有不同的影响。尤其是对于日本经济而言,资本质量对日本经济发展发挥了关键性的作用,日本经济的资本质量状况长期阻碍了日本经济的发展,这一点能够为日本经济自20世纪90年代以来的长期低迷提供一种可能的解释。为了进一步分析三国的技术进步与经济增长之间的关系,本文同时又将整个考察期划分为三个子时期,并对三个子时期内不同要素对各个国家的经济发展贡献程度进行了考察,分析结果进一步确认了前面的结论。     

我国西部地区经济增长中的技术因素分析

利用1978—2010年我国西部地区12省市的数据,测算了我国西部地区的资本、劳动力和TFP对经济增长的贡献率。结果显示:当期我国西部地区的经济增长主要源于资本投入;但是,由于资本对经济增长的贡献太大,因此TFP呈相对平稳下降趋势,TFP对经济增长的作用还不是很明显。指出:若2010—2020年西部地区TFP对经济增长的贡献率为37.1%,则西部地区能实现以技术进步带来可持续增长。最后提出西部地区实现经济可持续增长的政策建议。     

金融发展、投资扩张模式与中国的资本回报率*

本文从理论上分析了金融发展对资本回报率的影响机理，并使用中国省际数据进行了实证验证，得出的主要结论有：中国的资本回报率由2008年之前的平稳期进入到大幅度下降期，但区域间趋同趋势明显；中国金融发展不足与发展过度问题并存，其对资本回报率的影响也因地区不同而出现了明显差异，在投资扩张系数较高的地区存在着“金融失效”现象，在投资扩张系数较低的地区存在着“金融诅咒”现象，在投资扩张系数居中的地区存在着“结构失调”现象；政府干预会加剧金融发展的不利影响，但该作用在不断减弱；资本积累对技术进步促进作用的缺失，是资本存量对资本回报率产生负向影响的重要原因；劳动力增强型技术进步不仅促进了资本回报率的提升，还延续了投资驱动型增长的时期；技术进步是中国资本回报率提升的重要动力。     

Corruption and total factor productivity: level or growth effects?

This paper adopts a productivity-based perspective in order to study how corruption conditions the efficiency levels of the economies and their TFP growth rate. It attempts to identify the channels through which corruption can influence productivity growth, whether by conditioning improvements in relative efficiency levels or by shifting the production frontier. The results point out that corruption negatively affects both the levels of efficiency at which the economies perform and the growth rate of TFP, suggesting that the negative impact of corruption on technological progress manifest through its influence on human capital.     

前沿技术、吸收能力与中国区域 产业的协同发展*

本文以新增长理论为基础,构建了区域产业与前沿技术差距、区域产业自身发展条件和前沿技术吸收能力的整合空间面板实证分析框架,量化分析了前沿技术、吸收能力和空间外部性引致的产业全要素生产率的收敛机制。研究结论表明：区域产业与前沿技术的差距对于产业的全要素生产率收敛具有显著的促进效应,在短期体现为能够显著的促进区域全要素生产率的增长,长期则表现为存在长期协整关系;前沿技术的吸收能力能够显著地提高全要素生产率;空间溢出效应则进一步强化了这一效应。因此,提升区域产业自身对前沿技术的吸收能力,合理协调区域基础设施、研发创新等空间发展规划,是实现中国区域产业协同发展的有效途径,也有助于实现区域经济协调发展的宏观目标。     

对外开放与TFP增长：基于中国省际面板数据的经验研究

本文运用DEA的方法，先测算出1986--2003年各省域经济的技术效率、技术进步和TFP增长，然后实证研究人力资本、国际进出口及FDI对三者的影响。结果表明，人力资本和出口对技术效率的提高有正向作用，进口负向影响技术效率，FDI的影响不显著。出口对技术进步和TFP增长有轻微的负向影响，进口对二者具有小幅度的正向促进作用；而人力资本、FDI对技术进步和TFP增长的正向影响要大于进口。综合来看，对外开放能够促进TFP的增长，但是其影响只有人力资本正向效果的十分之一。     

中国服务业分行业生产率变迁及异质性考察

本文采用全国两次经济普查后的修订数据,引入"技术不会遗忘"假定,运用序列DEA-Malmquist生产率指数法测算了1990—2010年中国服务业细分行业的全要素生产率(TFP)、技术进步、纯技术效率与规模效率增长率。结果表明,中国服务业总体及细分行业的TFP均处于上升通道,在上世纪90年代,服务业TFP增长的主导因素是技术效率改进,进入21世纪后,则主要是技术进步提高,且技术效率改进已开始由以纯技术效率为主转向以规模效率为主,但服务业发展的粗放型特征仍然明显。同时,中国服务业TFP增长表现出了较大的行业异质性;与工业(制造业)行业对比,服务业TFP增长是滞后的。2010年与1991年相比,TFP及技术效率增长的行业间异质程度有所下降,而技术进步却有进一步拉大的迹象。可能的内在机制是现代信息技术对不同服务业企业资源配置的异质影响,以及中国服务业体制改革的渐进式道路。     

对外经济开放、区域市场整合与全要素生产率

本文在新增长理论的框架下,构建了一个对外经济开放和区域市场整合内生化全要素生产率的模型。在此基础上,利用中国1985—2008年的省际面板数据,采用工具变量两阶段最小二乘法(2SLS)实证检验了对外经济开放和区域市场整合对省际全要素生产率的影响。研究结果表明,对外经济开放和区域市场整合对中国省际全要素生产率都产生了显著的正向影响效应,而且二者存在替代关系。进一步的分析指出,在对外经济开放水平较高的沿海地区,区域市场整合对省际全要素生产率的影响效应较低,而在内陆地区则恰好相反。本文为理解中国省际全要素生产率的变化提供了新的视角,对后金融危机时代如何提升地区技术水平、转变经济增长方式也具有一定的启发意义。     

Technological progress and scientific indicators: a panel data analysis

Total factor productivity (TFP) is generally interpreted to be a proxy for technological advancement. In this paper, we use stochastic frontier analysis to decompose the growth in TFP into three components: technological progress, scale effect and change in technical efficiency. Then, we conduct a comprehensive panel data analysis using the technological progress component of the TFP growth and several scientific and technological indicators using data from 160 countries over the period from 1960 to 2009. Our results generally show that the technological progress component of the TFP growth properly reflects certain dimensions of actual scientific and technological progress. However, we also find that this result is somewhat sensitive to different econometric specifications and assumptions.     

对外开放与TFP增长:基于中国省际面板数据的经验研究

本文运用DEA的方法,先测算出1986—2003年各省域经济的技术效率、技术进步和TFP增长,然后实证研究人力资本、国际进出口及FDI对三者的影响。结果表明,人力资本和出口对技术效率的提高有正向作用,进口负向影响技术效率,FDI的影响不显著。出口对技术进步和TFP增长有轻微的负向影响,进口对二者具有小幅度的正向促进作用;而人力资本、FDI对技术进步和TFP增长的正向影响要大于进口。综合来看,对外开放能够促进TFP的增长,但是其影响只有人力资本正向效果的十分之一。     

资本匹配、创新力培育与区域协调发展：理论机制与经验证据

区域协调发展不仅受到资本积累数量的影响,更受到资本匹配质量的制约。在拓展MRW模型的基础上,理论分析“实物资本-人力资本-社会资本”最优匹配存在性与高效经济增长的关系,进一步构建资本匹配程度与匹配质量通过创新力培育实现落后地区经济赶超,进而影响区域协调发展能力的传导路径,并利用中国省级面板数据进行实证检验。结果表明,实物资本、人力资本与社会资本存量之间存在最优比例关系,且资本匹配质量主要通过创新力培育影响区域协调发展水平;资本匹配整体上有利于区域协调发展,东部地区资本匹配度对区域协调发展的促进作用高于中部地区、西部地区;机制检验发现,资本匹配通过组织创新效应实现区域协调发展的解释程度最大,其次为技术创新效应,最后是产业创新效应。     

Factor function characteristics and origin of economic growth of China

The paper makes an empirical study on factor contribution and its stage variation characteristics during 1952–2005 and 1978–2005 in China. GMM and OLS tests show that the robustness and significance level of the institution, the physical capital and human capital’s contributions are much higher than other factors, and 70% of economic growth is boosted by the capital and the labor input. Factor contribution decomposition and TFP growth indicate trade has the most remarkable influence on economic growth. The state space model finds that physical capital, human capital, technological progress, finance, trade and institution have different effects on economic growth in different periods. Namely, factor contribution does have the characteristics of stage variation.     

GAUGING THE SOURCES OF GROWTH OF HIGH‐TECH AND LOW‐TECH INDUSTRIES: THE CASE OF KOREAN MANUFACTURING*

Literature argues that the source of growth for high‐tech industries emanates from technological progress, while that for low‐tech industries comes from technical efficiency improvement. Also, some empirical studies have shown that technological progress is often accompanied by deterioration in technical efficiency. The focus in this study is to discuss a methodology and test the above two hypotheses with regard to Korean manufacturing data from 1970 to 1997. The study found that the 2.5 per cent average annual rate of technological progress during this period was the major contributor to total factor productivity (TFP) growth in Korean manufacturing whereas technical efficiency grew by a modest 1.1 per cent per annum. The analysis also showed that technological progress was responsible for TFP growth in both high‐tech and low‐tech industries and that both technological progress and technical efficiency improvement co‐existed in the case of Korean manufacturing industries.     

人力资本对我国全要素生产率增长作用的空间计量研究

通过构建距离衰减的空间权重矩阵,利用空间Benhabib-Spiegel模型探讨人力资本空间溢出对全要素生产率增长的影响,结果表明:人力资本对全要素生产率增长的作用取决于考察省区人力资本水平、邻近省区人力资本水平,以及考虑地理距离的考察省区技术追赶效应;人力资本平均水平对全要素生产率增长起到积极的促进作用,邻近省区人力资本对考察地区TFP增长产生正向空间溢出效应。各省区若要充分发挥人力资本的空间溢出效应,就必须选择均衡适度的人力资本配置结构。     

On modeling the determinants of TFP growth

We investigate the determinants of TFP growth of Italian manufacturing firms. Using stochastic frontier techniques, we consider three approaches for taking into account the influence of external factors, i.e., the determinants or drivers of growth. First, in our novel approach external factors may influence the technological progress, that is the shift of the frontier. To model this possible unexplored effect, we extend the standard time trend model to make it a function of the external factors. Then, following more standard approaches, we model external factors as either influencing the distance from the frontier, i.e., inefficiency, or the shape of the technology. Using a sample of manufacturing firms in 1998–2003, we find that technological investments and spillovers, human capital and regional banking inefficiency all have a significant effect on TFP growth.     

出口贸易、FDI与中国农产品加工业全要素生产率——基于行业面板数据的实证分析

通过利用中国农产品加工业12个子行业的面板数据,首先运用DEA的Malmquist方法测算了中国农产品加工业全要素生产率及其分解,之后重点考察了包括出口贸易和外商直接投资在内的各因素对全要素生产率的影响。研究结果发现:在2001-2011年期间,中国农产品加工业全要素生产率整体处于上升趋势,支持了中国农产品加工业全要素生产率平均增长率上升的动力主要来自于技术进步;出口贸易的发展对农产品加工业全要素生产率和技术效率的提高作用并不明显;外商直接投资所带来的技术溢出对于提高中国农产品加工业的全要素生产率有较好的促进作用。根据研究结论,文章得到的政策启示是:提升农产品加工业出口贸易对全要素生产率的正向作用;强化外商直接投资所带来的技术溢出效应;提高农产品加工业人力资本水平;改善农产品加工业RD投入结构和市场环境;改进农产品加工业的规模经济效应。     

Environmental regulation and the productivity of Japanese manufacturing industries

This paper attempts to provide empirical evidence on issues concerning: (a) the effect of the stringency of environmental regulations (as measured by pollution control expenditures) on innovative activity (as measured by R&D expenditures) and on the average age of capital stock and (b) the productivity enhancement effect of environmental regulations in Japanese manufacturing industries. The empirical findings in the paper show that the pollution control expenditures have a positive relationship with the R&D expenditures and have a negative relationship with the average age of capital stock. It is also shown that increases in R&D investment stimulated by the regulatory stringency have a significant positive effect on the growth rate of total factor productivity.     

全要素生产率与中国经济增长关系研究——基于VAR模型视角

运用TFP的变动来对经济增长潜力展开分析,是国内外经济学界的常见研究思路。从新古典模型出发,对改革开放以来的中国TFP进行估算分解,并构建TFP、GDP增长、资本增长和劳动力增长之间的VAR模型。实证研究认为,目前中国已进入跨越式发展时期,应大力发展资本市场,促进资本要素的有效流动,促进产业结构优化,将提高劳动力受教育水平作为重要发展战略,注重进行技术基础的革新,提高经济增长质量,促进经济发展方式向集约型发展方式转变。     

Capital services estimates in Portuguese industries, 1977–2003

This paper presents capital services estimates for 26 Portuguese industries for the 1977–2003 period. The estimation procedure follows an integrated approach under which the flows of capital services are approximated as a proportion of the capital stock converted into standard efficiency units. Our findings suggest a close proximity between the evolution of capital flows and the observed fluctuations of Portuguese macroeconomic growth. TFP growth estimates based on growth accounting reveal, furthermore, a very disappointing performance of the Portuguese economy during the period under study, with an average annual rate of TFP growth of 0.8% being observed. Performance varies across industries, but the bulk of activities show very modest rates of TFP growth.     

The impacts of membership in multi-hospital systems on cost,productivity growth and technical change

We examine whether affiliation in a multi-hospital system contributes to higher rates of total factor productivity (TFP) growth, technological progress and cost efficiency. With a 1996 to 1999 panel of 248 US hospitals (some are private nonprofit (church-related and other nonprofit) and the remaining are public (government, nonfederal)), empirical results indicate that urban system member hospitals experienced higher rates of both TFP growth and technical progress than the rates of TFP growth and technical progress experienced by urban nonsystem hospitals. Rural system member hospitals experienced smaller rates of both TFP decline and technical regress than the rates of TFP decline and technical regress experienced by rural nonsystem hospitals.
