文章借鉴Feder非均衡模型的思想,构建了一个反映工业发展对经济发展影响的非均衡计量经济模型。模型分析表明,工业部门比非工业部门边际生产率更高,工业部门对非工业部门存在正的外部性,将更多的资本、人力等资源配置到工业部门有利于提高整个经济的生产率水平,推进产业结构升级,促进经济增长。     

部门间生产率差距、劳动力去工业化与结构性减速

基于中国劳动力就业结构出现过快和过早去工业化的迹象，本文从部门间生产率差距的视角，利用多部门一般均衡模型、数值模拟和计量实证分析方法研究发现：（1）理论上，当服务业劳动生产率增长慢于工业，部门间生产率差距将扩大，导致劳动力去工业化速率加快；且部门间生产率差距的存在使得劳动力去工业化对经济增长产生结构性减速效应。服务业部门生产率加快提升，部门间生产率差距将会缩小，从而减缓去工业化速率和降低结构性减速压力；工业部门生产率提升尽管会扩大部门间生产率差距从而加快劳动力去工业化，但在长期中起到均匀化经济增长速率的作用。（2）利用2001—2018年中国省级和城市级面板数据的计量实证分析发现，部门间生产率差距的存在导致劳动力去工业化的效应在全时段样本下显著，但劳动力去工业化对经济增长的结构性减速效应仅在2009—2018年区间样本下显著，表明近年来中国经济增长减速与部门间生产率差距及其导致的劳动力去工业化相关。（3）赶超成功与失败国家的经验比较也表明，工业与服务业部门劳动生产率的改善与协调是跨越中等收入陷阱以及跨越后实现持续赶超的关键。     

The political economics of complexity : From the information economy to the ‘complexity’ economy

The economics of information allows one to distinguish within the national product the real production from the costs of organization. It reveals a continuous inflation of these costs which, per employee and since 1900, has been twice as fast as the increase of productivity. From this, one can conclude that the growth of productivity comes up against a real ‘wall’ when the costs of organization approach 50% of the national product. This is the essential cause of the present crisis. The author subsequently designs an economy of organization structures applicable to complex systems, such as physical, biological or social systems. He shows how the 50% wall is characteristic for centralized structures. Most economic structures are those where social forces and solidarities are distributed justly among all levels of organization, from local to global ones. They tend to establish themselves by self-organization, but a new political economy applying these principles would, aided by information and communication technologies, accelerate this process.     

The Japanese information economy: Its quantification and analysis in a macroeconomic framework (with comparisons to the U.S.)

Japan is one of the leading information societies and there is official policy promotion of its information economy image. In this study the information sector of Japan is measured and analysed within a macroeconomic framework, using input-output techniques. Important benchmark statistics on both the primary and secondary information sectors are derived and compared to those obtained in an earlier study of the U.S. The analysis reveals the high growth potential of both information sectors in the two economies. However, important inter-country differences also emerge, in particular in regard to the amount of resources devoted to the information task at the disaggregated sector level. This leads to a discussion of the relationship between investment in the information sector, organisational design, informational efficiency and productivity growth, which is seen to be of crucial importance for the future success or failure of the two economies. Limitations of the approach adopted in this study and areas for further research are indicated.     

Towards an information economy : The case of Singapore

Recent empirical studies have documented the emergence of information-based economies in developed countries within Europe, the U.S.A., Japan, and Australia. Casual observations suggest that the newly industrializing country of Singapore is proceeding towards a similar trend. The primary purpose of this paper is to account for the share of Singapore's national product which originates from informational activities. In particular, we define and estimate the size of Singapore's information sector within an input-output framework. Our results indicated that a sizable portion of Singapore's economy is information-based. In view of the significant penetration of informational activities in economic production, advances in communication technology and concomitant improvements in information-handling capabilities are bound to affect factor productivities and incomes with consequences for a country's pattern of employment and production structure. It is anticipated that an economics of communication becomes necessary for an awareness of communication technology as a choice variable in economic planning. We conclude our discussion with an assessment of the admissability of an information sector concept in economic analysis and the usefulness of empirical studies based on such a concept.     

Hiding in Plain Sight: A Note on Public Goods,Information Technology,and Productivity

This research note advances a conjecture that may help to explain the “paradox” of productivity and information technology (IT). Conventional measures of the economic output of the IT sector may substantially understate the actual value of IT because software is a public good, which is largely unpriced. I provide a simple exploratory calculation that lends plausibility to this explanation. I hope that this conjecture may inspire research by those with greater expertise in the evolution of software.     

Industrial structure and jobless growth in transition economies

When does employment growth mirror aggregate growth? Applying a two sector model, where productivity growth differs across sectors of production, this article is concerned with a feature characterising a number of transition economies: a divergence between production and employment growth. In our framework the industrial structure that allows employment growth to mirror output growth is endogenous, and related to a number of industry- and economy-wide characteristics. The article shows how the critical industrial structure necessary for avoiding ‘jobless growth’ is context-specific, questioning a ‘one size fits all’ policy approach when aiming to fulfil the Europe 2020 Strategy.     

Efficiency change,technological change and capital accumulation in Italian regions: a sectoral study

This paper examines the sources of labour productivity in the Italian regions during the period 1980–2004. Five economic sectors are investigated using data envelopment analysis (DEA) and taking into account productive specialisation and sector inefficiencies. Labour productivity change is decomposed into five components by means of Malmquist productivity indices: intra-sector efficiency change, composition efficiency change, input-biased technical change, magnitude component technical change and capital accumulation. Using bootstrap procedure, the components of labour productivity changes are statistically tested. Efficiency analysis shows that productive specialisation is not a source of inefficiency and efficiency gains can be obtained by sector-specific policies. Thus, it is possible to obtain improvements in efficiency in each sector of activity rather than reallocating resources among sectors. The results of the decomposition by sectors reveal heterogeneous sources of growth. The total economy has shown evidence of non-neutral technical change and, it has been found that agriculture, industry and construction experienced capital using technical change. The analysis of the decomposition of the labour productivity growth is complemented by an analysis of β-convergence.     

Effects of re-invention on industry growth and productivity: evidence from steel refining technology in Japan, 1957–1968

This paper examines the economic impact of re-invention – the degree to which an innovation is modified by user – on industry growth and productivity. The paper focuses on two re-inventions made by a Japanese steel company; these inventions improved the productive efficiency of Austrian-made refining technology, namely basic oxygen furnace (BOF). Results obtained from the plant-level production function estimation indicate that re-inventions account for approximately 30% of the total factor productivity of the BOF, substantially promoting the dissemination of the BOF technology. Our simulation analysis indeed reveals that re-inventions contributed to steel output growth by about 14%. This paper also documents that innovating companies played the role of a ‘lead user’ in developing and disseminating their re-invented technologies.     

Efficiency and productivity in the Indian unorganized manufacturing sector: did reforms matter?

This paper analyzes total factor productivity growth of the unorganized manufacturing sector in India using several rounds of the large scale national sample survey state level data for 15 major Indian states for the period 1978–1979 to 2000–2001. Data envelopment analysis is used to compute Malmquist total factor productivity index and its components. The impact of economic reforms on efficiency and productivity is examined. Evidence suggests that total factor productivity registered a positive growth during the period in the country as a whole. Most states in the country witnessed higher total factor productivity growth in the post 1990s reforms period than in the pre-reforms period. Decomposition of the Malmquist productivity index shows that improvement in technical efficiency rather than technical progress had contributed to the observed acceleration in the growth rate. Econometric analysis of the determinants of total factor productivity growth demonstrates that ownership, literacy, farm growth and infrastructure availability significantly influence total factor productivity growth in the sector.

Environmental productivity and Kuznets curve in India

As a result of India's extremely rapid economic growth, the scale and seriousness of environmental problems are no longer in doubt. Whether pollution abatement technologies are utilized more efficiently is crucial in the analysis of environmental management because it influences the cost of alternative production and pollution abatement technologies. In this study, we use state-level industry data of sulfur dioxide, nitrogen dioxide, and suspended particular matter over the period 1991-2003. Employing recently developed productivity measurement technique, we show that overall environmental productivities decrease over time in India. Furthermore, we analyze the determinants of environmental productivities and find environmental Kuznets curve type relationship existences between environmental productivity and income. Panel analysis results show that the scale effect dominates over the technique effect. Therefore, a combined effect of income on environmental productivity is negative.     

Services,innovation and the new economy

Several distinctive stylized facts form the new economy, an information technology service sector organized in network forms of organization, an inflation rate below its fundamentals, an increase in stock market volatility, high rates of economic growth, but apart from a small information technology manufacturing sector low productivity rates. This paper presents a model where the innovation of new service varieties can explain all of these facts. First, productivity gains are no longer realized within but between firms, as the increase in variety increases value-added per employee. Whilst service innovators, such as the information technology manufacturers, get ever more productive, individual service firms will exhibit low productivity. It is this unmeasured sectoral productivity gain, which is the key element in understanding the intrinsic inertia in the price index. Finally, the paper shows that variety in the service sector enables service providers to realize rents, where fluctuations of these rents are the basis of more than proportional changes in the firms' stock market value.     

中国钢铁行业全要素生产效率实证分析

基于动态DEA的非参数Malmquist指数法,分析了1992～2007年中国28个省市钢铁行业全要素生产率以及七大经济区钢铁行业全要素生产率变动情况,并将全要素生产率的变动分解为技术进步、纯技术效率、规模效率三个指标,分析了这三个指标对中国钢铁行业全要素生产率的影响。结果显示,中国钢铁行业TFP的增长主要是由技术进步推动的,当技术进步促进TFP提升时,总会受到技术效率相对下降对TFP增长的抑制;七大经济区钢铁行业全要素生产率存在明显级差,低效经济区学习和追赶高效经济区的效应也应该发挥更大作用;钢铁产业各经济区产能应实现在高效率地区的相对集中,获取行业的规模经济;各经济区都应该注重钢铁行业管理水平的提高,突破钢铁行业能效提高的技术效率瓶颈。     

中国能源生产率的影响因素分析

This paper identifies the determinants of energy productivity based on a basic economic growth model. Using panel data including 29 provinces from 1995 to 2007, we find that energy productivity is negatively associated with the industry sector share in GDP and the state-owned sector share in GDP, and is positively associated with the electricity share in energy consumption. In addition, we find that there exists a big gap of energy efficiency among eastern, middle and western region in China. Our results suggest that we should induce the industry development structure from the industrial sector to service sector, prompt the reform of state-owned enterprises, as well as improve the energy consumption structure dominated by coal to diversified cleaning energy.      

Export Growth,Capacity Utilization,and Productivity Growth: Evidence from the Canadian Manufacturing Plants

Aggregate labor and multifactor productivity growth slowed substantially post‐2000 in the Canadian manufacturing sector. To examine the source of the decline, this paper proposes a decomposition method that delves deeper into the two micro‐components of aggregate productivity growth: a within‐plant component and a between‐plant component. The decomposition builds on earlier work by Jorgenson and his collaborators that decomposes aggregate productivity growth into its industry components, but applies it to the plant level and introduces non‐neoclassical features of the plant‐level economic environment. It finds that the preponderance of the aggregate labor and multifactor productivity growth slowdown is due to the pro‐cyclical nature of productivity growth arising from capacity utilization. Almost all of the aggregate productivity growth slowdown is driven by exporters, as exporters experienced large declines in labor productivity growth in the post‐2000 period as a result of large declines in their capacity utilization.     

In-house information activities in an applied general equilibrium framework

Increasingly, firms' activities consist of information generating and processing activities, and information costs tend to dominate production costs. This indicates the necessity for explicitly incorporating private bureaucracies in economic modelling, if we want to understand economic development. Porat and Rubin's concept of the ‘secondary information sector’, which accounts for non-marketed information services produced in-house, is an attempt to account for and analyse intra-firm information activities at an industry and economy-wide level. The present study extends their work by embedding the sector in a simple computable general equilibrium model, using Japan in 1980 as an illustrative case study. Scenarios modelling changes in sectoral exports and domestic demand are conducted. Advantages and disadvantages of the secondary information sector concept are highlighted and areas for further research are indicated.     

China's Recent Economic Performance and Future Prospects*

Our forecast of China's economic future is based primarily on the supply side growth accounting model. The life cycle model of household saving provides us with the most plausible explanation for a continued high rate of savings and investment. China's labor force will soon stop growing, but migration out of agriculture should have little impact on farm output while providing a steady stream of labor to the modern more productive sectors. There is also room for rapid expansion of human capital. Maintaining high productivity growth will depend primarily on strengthening currently weak institutions, notably the financial sector and, more importantly, the legal system.

Developmental aspects of China��s trade pattern: The role of imported intermediate goods

This paper studies the relationship between China’s trade and its economic development. More than two centuries ago Adam Smith argued that it is the use of imported intermediate goods that constitutes the vector through which openness improves productivity. Imported intermediate goods can relieve what would otherwise be key constraints allowing faster growth, together with better human development. While China’s trade reform is often related to its productivity growth, there has been remarkably little attention to the relationship between imports and productivity growth at the industry-sectoral level. Our paper examines the sector-specific impact of intermediate goods utilizing a time series for the share of imported intermediate goods in each sector derived from our model calculations. Our study indicates that imported intermediate goods are playing an important role in the growth of Chinese productivity.     

Modeling the diffusion of general purpose technologies in an evolutionary multi-sector framework

General purpose technologies (GPTs) are characterized by their pervasive use in the economy. The introduction of a new GPT (product innovation) as well as increasing productivity within a GPT-sector (as a consequence of process innovations) affect the economy in several ways. First, a new GPT offers the opportunity to produce goods by means of cheaper processes; secondly, technical change within the GPT sector influences productivity gains in related sectors. Also social consequences such as changing wage share, technical unemployment and transitional wage inequality can be observed. Finally, the emergence of a GPT often coincides with output decline, preceding economic growth. This paper introduces a multi-sector diffusion model to study these effects by combining classical economics and replicator-dynamics. Empirical evidence is given by the information and communication technology sector in Denmark and its impact on the economic structure from 1966 to 2007.
