Economic growth and sector dynamics

This paper analyzes the endogenous determination of sectors in a growing economy. It assumes that there are traditional sectors and modern sectors and economic growth is driven by rising productivity of the modern sectors. It also assumes that individuals are heterogeneous, which leads to increasing marginal opportunity costs in creating new modern sectors. We show that under these main assumptions, economic growth first increases diversification to sectors and then reduces it. We also show that for the equilibrium to be stable and well-behaved, it is required that the modern and traditional sectors should be substitutes and not complements.

Structural Change and Economic Growth in China

This study develops a new analytical framework to account for sources of rapid economic growth in China. The traditional Solow approach is expanded to include another source of economic growth—structural change. The empirical results show that structural change has contributed to growth significantly by reallocating resources from low‐productivity sectors to high‐productivity sectors. It is found that the returns to capital investment in both agricultural production and rural enterprises are much higher than those in urban sectors, indicating underinvestment in rural areas. On the other hand, labor productivity in the agricultural sector remains low, a result of the still large surpluses of labor in the sector. Therefore, further development of rural enterprises and an increase in labor flow among sectors and across regions are key to improvements in overall economic efficiency.     

Growth,economic structure,and residential distribution of a small city

This article presents a growth model of a small open city with economic structure and geography. The city which is located along a line segment has three, industrial, services and housing, sectors. The spatial growth model of a small city synthesizes the main ideas in some important models in the neoclassical growth theory, urban economics, and the literature of economic growth of small open economies. We show that the dynamic system has a unique equilibrium. We also simulate the motion of the urban economy over time and space. The unique feature of our approach is to treat production activities, economic structure, residential distribution, capital accumulation, and consumption on the basis of microeconomic mechanism as an integrated whole. Our simulation provides some important insights into the processes of the urban economic growth. For instance, under certain conditions, when the industrial sector’s productivity is increased, the wage rate, price of services, capital intensities of the services and industrial sectors, and per-worker output levels of the two sectors are increased. The total labor supply, the capital stocks employed by the three sectors and the labor forces by the service and industrial sectors are all increased. The shares of the three sectors are not affected by the technological change in the long term, even though the shares are initially affected. The per capita consumption level of the industrial goods rises and the consumption level of services falls. The land and housing rents are increased and the consumption of housing per household falls. Moreover, the current account balance tends to be more in surplus and the growth rate is increased.     

A New Typology for Economic Sectors with a view to Policy Implications

This paper is an attempt to tease out a typology of economic sectors based on a systems approach to innovation and economic growth that may be useful for policy analysis. The typology explored here revolves around novel products rather than ethereal knowledge-producing entities. This insight goes back to Allyn Young (1928) and Joseph Schumpeter (1934) who argued that the introduction of new goods was the engine of economic growth. More precisely, our typology of sectors focuses on novel products which are efficiency-enhancing within and between sectors through the market mechanism. The scheme revolves around the relationship between 'Enabling' and 'Recipient' sectors (which gives the typology its name: ER), and offers a lens for viewing and interpreting a substantive part of the mechanics of modern economic growth. The last part of the paper briefly discusses a few immediate policy implications, although it has the potential for greater use and value in this regard.     

An input–output model of water consumption: Analysing intersectoral water relationships in Andalusia

This paper presents an input–output model of sectoral water consumption, created by combining the extended Leontief input–output model with the model of energy use developed by Proops. The analysis is applied to Andalusia, a region situated in the South of Spain which is characterized by water shortage. We determine which economic sectors consume the greatest quantities of water, both directly and indirectly, and to what extent this natural resource may become a limiting factor in the growth of certain production sectors. The model allows us to distinguish between direct and indirect consumption, thus offering the possibility of designing an economic and environmental policy oriented towards water saving. Additionally, the model allows simulation of possible changes in water consumption caused by certain environmental measures, as well as their consequences on the regional economy.     

Satiation in an evolutionary model of structural economic dynamics

This paper presents the problem of satiation of consumption and technology in relation to a model of evolutionary endogenous growth. The model represents an attempt to provide an evolutionary economic micro foundation to Pasinetti's scheme of the structural economic dynamics of an economy that is based on only labour and knowledge. The micro foundation is based on a set of rules that makes endogenous the demand coefficients, the labour coefficients, and the number of available sectors. Through process innovations firms increase their productivities with respect to individual goods, but a growth slowdown takes place unless the benefits from specialisation are exploited at still higher levels. Another cause for slowdown is related to an Engelian hierarchy of goods. As the standard of living grows, existing sectors and consumption goods satiate, so new sectors need to be provided by product innovations in a sufficient pace to keep up with the labour that is displaced from old sectors.     

我国垄断行业收入与经济增长关系的实证研究——基于面板协整理论

基于1990—2008年我国垄断行业收入的面板数据,通过面板协整、Engle-Granger检验以及运用误差修正模型对我国垄断行业的收入水平与经济增长的长期关系进行分析。研究结果显示:与能源、交通相关的垄断行业的收入与经济增长之间存在长期稳定的协整关系;与能源相关的垄断行业的收入对经济增长具有正向影响,而与交通相关的垄断行业的收入对经济增长的影响不太显著;金融保险业和房地产业的收入与经济增长之间并不存在长期稳定的面板协整关系。     

Decomposition of Productivity Considering Multi‐environmental Pollutants in Chinese Industrial Sector

The objective of this study is to calculate and decompose productivity incorporating multi‐environmental pollutants in Chinese industrial sectors from 1992 to 2008. We apply a weighted Russell directional distance model to calculate productivity from both the economic and environmental performance. The main findings are: (1) Chinese industrial sectors increased productivity, with the main contributing factors being labor saving prior to 2000; (2) The main contributing factors for productivity growth in coastal areas include both economic and environmental performance improvement. While central and western regions improved productivity owing to economic development, they have a trade‐off relationship between economic and environmental performance.     

Modelling regional policy scenarios in the agri-food sector: a case study of a Spanish region

The agri-food industry has several features of great importance for sustainable economic growth in rural areas. The objective of this work is to evaluate the effects associated with different scenarios of growth, and changes in the regional agri-food industry. These scenarios simulate changes in exports and imports, changes in technology and changes in the level of industrial integration. We develop a computable general equilibrium model calibrated for the region. Our results indicate that policies trying to improve the competitiveness and dynamism of strategic sectors as the agro-industrial complex in this regional economy exert positive effects on its growth and income, having notable impacts on local job markets but also in other sectors and activities linked through the whole production chain.

Corporations and local economies in the Brazilian Amazon: the impacts of the mining sectors scheduled investments in Southeastern Pará (2004–2010)

Southeastern Pará is an extraordinarily dynamic region. There were large cattle ranching projects, financed in the 1960s. Expansion of peasant agriculture, mineral projects and gold prospecting followed the ranching projects. Also important structural transformations reinforced the role of the urban centres and the local rural bases in the logistics of new economic sectors conditioned by the presence of Companhia Vale do Rio Doce (CVRD), in the region since 1985. This article presents the results of an input–output analysis of the investment programme of CVRD from year 2004 up to 2010. The main findings are that the mineral sector has achieved a considerable influence over the economy of Southeastern Pará, so that during the cycle of investments each 1% in the growth of the mineral production creates growth possibilities of about 0.83% for the agricultural sector and about 0.86% for the local urban sectors. Considering just the production growth, a percentile point will imply growth at, respectively, 0.73% and 0.76% for those sectors. For the economy of the rest of the state of Pará, those elasticities would be, incorporating the investments, 0.80% and, without them, 0.68%. For the economy of the rest of Brazil they would be, respectively, 0.88% and 0.78%.     

全球制造业工资停滞之谜*——来自进口中间产品质量视角的经验证据

本文从快速增长的中间产品贸易及其质量视角研究了全球制造业工资停滞现象。首先，基于DS垄断竞争框架和Koch & Smolka(2019)的研究，本文重新构建开放条件下的工资决定模型，发现进口中间产品质量影响各国劳动工资。其次，借鉴Feenstra & Romalis(2014)的研究，本文构建全新的测度产品—行业—国家层面进口中间产品质量GEKS 指数法，估算1995—2011年37个国家从248个出口市场进口的制造业四位码中间产品质量指数，发现全球制造业进口中间产品质量上升趋势明显但分化严重，中等和低等收入国家质量指数持续上升，高等收入国家质量指数持续下降。最后，本文从跨国—行业层面定量识别进口中间产品质量对进口国制造业工资的具体影响，发现：(1)进口中间产品质量对全球制造业的劳动工资有显著负向影响，对中等收入国家、中级技术密集型行业、高技能劳动者以及进口矿物类中间产品制造业的工资降低效应最大；(2)进口中间产品质量通过“就业破坏效应”和“研发激励效应”两种机制造成全球制造业工资下降；(3)进口中间产品质量变化造成制造业工资下降是全球化中的市场性经济规律和暂时性“全球冲击波”。上述发现解释了全球制造业工资停滞之谜，并启示各国须尊重全球化的市场规律，加强国际合作，共同应对冲击，提高民众福祉，携手共建人类命运共同体。     

Forecasting material and economic flows in the global production chain for silicon

Material and economic flows in a global production chain are analyzed in order to identify shifts in economic structure relevant to environmental issues. Results suggest that the economic and environmental weight of high-tech manufacturing and specialized material sectors will increase significantly relative to extractive and primary commodity sectors, perhaps reaching a similar environmental scale within a few decades. Though further study is needed, the forecasts suggest that a reprioritization of analysis and policy to address these new industries is in order. These results are based on a case study of the global production chain for high-purity silicon and its use in semiconductors, solar cells and optical fiber from primary materials. Forecasts for future material/economic flows are carried out based on the identification of time scales that reveal stable long-term trends. Assuming constant growth over 7–10 year averages reproduces thirty years of historical growth of three global sectors to around 1–2% accuracy. This suggests the constant growth model can be used to forecast with a relatively high degree of confidence.     

A two-sector Kaleckian model of growth and distribution with endogenous productivity dynamics

This study extends a two-sector Kaleckian model of output growth and income distribution by incorporating endogenous labour productivity growth. The model is composed of investment goods and consumption goods production sectors. The impact of a change in wage and profit shares on capacity utilisation and output growth rates at the sectoral and aggregate levels are identified. The study reveals short-run cyclical capacity utilisation rates and productivity growth dynamics. Even if the short-run steady state is stable, the capital accumulation rate in the consumption goods sector must decrease more than that in the investment sector for long-run stability. When simultaneous rises in profit shares in both the sectors affect long-run aggregate economic growth differently at a steady state, the distributional interests between the same class in different sectors may hamper the long-run economic growth. A policy message is that the effect of income distribution on industrial output growth is not always beneficial. These phenomena are specific to two-sector models and cannot be observed when using conventional aggregate growth models.     

Frontiers and sustainable economic development

Exploiting new resource “frontiers,” such as agricultural land and mineral reserves, is a fundamental feature of economic development in poor economies. Yet frontier-based development is symptomatic of a pattern of economy-wide resource exploitation in developing economies that: (a) generates little additional economic rents, and (b) what rents are generated are not being reinvested in other sectors. Such development is inherently unsustainable. The following paper explains this phenomenon, and provides evidence that long-run expansion of agricultural land and oil and natural gas proved reserves across poor economies is associated with lower levels of real income per capita. The paper proposes a frontier expansion hypothesis to explain why the structural economic dependence of these economies on frontier land expansion and resource exploitation is not conducive to sustained long-run growth. The key to sustainable economic development in poor economies will be improving the economic integration between frontier and other sectors of the economy, targeting policies to improved resource management in frontier areas and overcoming problems of corruption and rent-seeking in resource sectors.      

A new approach to determining sectoral priorities in an economy: input–Output elasticities

This paper uses input–Output elasticities to identify important economic sectors. Elasticities of output employment and income are used to identify key sectors of the Greek economy. A comparison of the rankings of economic sectors based on input–output elasticities with those based on net backward linkages indicates significant divergence in sectoral rankings obtained from the two approaches. The elasticity approach yields more consistent estimates of sectoral output employment and income potentials than the net backward linkage approach. Measured in terms of the potential to generate output employment and income agriculture services and textiles are found to be the key sectors for the Greek economy.
