Diversity Analysis of Structural Change Based on the Canadian Input–Output Tables

This article presents some of the results of a study conducted at Statistics Canada that involved the analysis of the variability through time of input–output structures. All structures have been analyzed in current and constant prices over the period 1961–84, but only the results about the industries' input structures in current prices are reported in this article. Structural changes are assessed over time horizons of 1, 2 and 5 years, using the Kullback, cross-entropy index formula. Structural changes in the current prices input structure are decomposed into a price and a quantity component, following a new decomposition of the entropy formula. It is shown from that decomposition that the traditional analysis of the variability of constant prices input–output structures may be quite misleading. The authors have found that structural changes generally follow a smooth path through time and tend to be cumulative in the long run, with some cyclical fluctuations in the short term. Some of the structural changes appear to be due to statistical events (establishment moves across industries, changes in methodologies, etc.) rather than reflecting real phenomena. The quantity component of structural change appears to be more important than the price component in almost all time periods and time spans, except when the Canadian economy was subjected to important price shocks during the 1970s.     

Input–Output Anatomy of China's Energy Use Changes in the 1980s

China significantly reduced the energy intensity of its economy in the 1980s. In this paper, we conduct a structural decomposition analysis to explain China's energy use changes between 1981 and 1987—the years for which we have input–output tables. We find that China's energy saving during this period came about primarily by changes in how to produce (production technology changes) rather than changes in what to consume (final demand shifts). The driving force of the energy intensity decline was energy efficiency improvements, which were multiplied across the entire economy through inter-industry input–output linkages.

Sources of Structural Change in Input–Output Systems: A Field of Influence Approach

The analysis of structural change with input–output (IO) tables is extended beyond the initial ideas of Chenery and Watanabe, and beyond the recent applications of Feldman et al. and Dewhurst, to embrace a more comprehensive view. With this perspective, change is decomposed into three initial components, and these components are further divided into change initiated within the sector and outside the sector. The analysis is then linked with the notion of a ‘field of influence of change’ to provide a more complete view of the way in which changes penetrate the rest of the economic system. The analytical perspectives are illustrated with applications to a three-sector set of IO tables for the US economy for the period 1948–77.     

Structural production layer decomposition: a new method to measure differences between MRIO databases for footprint assessments

Recent empirical assessments revealed that footprint indicators calculated with various multi-regional input–output (MRIO) databases deliver deviating results. In this paper, we propose a new method, called structural production layer decomposition (SPLD), which complements existing structural decomposition approaches. SPLD enables differentiating between effects stemming from specific parts in the technology matrix, e.g. trade blocks vs. domestic blocks, while still allowing to link the various effects to the total region footprint. Using the carbon footprint of the EU-28 in 2011 as an example, we analyse the differences between EXIOBASE, Eora, GTAP and WIOD. Identical environmental data are used across all MRIO databases. In all model comparisons, variations in domestic blocks have a more significant impact on the carbon footprint than variations in trade blocks. The results provide a wealth of information for MRIO developers and are relevant for policy makers designing climate policy measures targeted to specific stages along product supply chains.     

Structural change and female participation in recent economic growth: a multisectoral analysis for the Spanish economy

ABSTRACT

Economic growth has different impacts on gender gaps. In recent decades the growing participation of women in the labour market has reduced the gender employment gap, however a notable gender pay gap still persists standing at around 15% on average in the European Union. In this context, this paper evaluates the impact of economic growth patterns on the evolution of gender employment and pay gaps. First, sectorial feminization, direct discrimination, and structural change factors are identified and evaluated as ways to explain changes observed in the gender pay gap. Second, we explore the influence of demand, technology, and intensity factors on the evolution of employment combining gender, skill, sectorial, and temporal perspectives. As a case study, we examine Spanish economic growth from 1980 to 2007 and the influences on the size, composition (by skill), and distribution (by sector) of female and male employment, as well as the consequences for gender gaps. Our results show that structural change contributed to reduce the gender employment gap in Spain; while the evolution of the gender pay gap is less conclusive, following a sort of inverted U-shape. This paper shows the suitability and potential of the multisectorial input–output framework to analyse structural and technological changes and their impacts on the gender employment and pay gaps.     

Does It Make Sense to Apply the Static Open Input–Output Model for Imputation and Structural Decomposition?

This paper aims to stimulate discussion on the question concerning whether input–output (10) analysts should go on applying the static open 10 model in times when data supply and computer capacity allow us to switch to semi-closed 10 models, which are rated as comparative improvements. It is argued that the most frequent of the open 10 model's applications, i.e. imputations and structural decompositions, with a switch to a semi-closed model, lose the properties which make them so attractive: imputations no longer are straightforward assignments of production and primary inputs to the components of total final demand; structural decomposition no longer is an additive assignment of changes of production and primary inputs to sources of structural change. In the author's opinion, imputations and structural decompositions on the basis of the open 10 model should be abandoned.     

Financial and Structural Stimuli for Regional Growth

The economies during the post-industrial era are returning to the classical meaning of manufacturing sector in the process of balanced regional growth and are searching for stimuli for diversifying economic structure and reindustrialization. Expansion of a new growth theory highlighted the necessity for the well-developed so-called innovative manufacturing sector; however, stimuli for realizing the potential of this sector are limited due to relative attractiveness of sectors with lower risks and faster returns especially in regions followers. Moreover, regional success as a result of the previous development can hinder changes and stimulate economic agents to avoid regions and sectors with high potential but weak performance. Generation of regional economic growth can be considered in a framework of two kinds of stimuli as financial and structural. Financial capital as an important factor for supporting structural change in economy helps to stay in harmony with the modern economy; however, existing sectoral composition can be persistent to changes. Latvia is considered as a case study about issues on fmancial and structural stimuli for regional growth because of the bright dominance of capital city region （high regional differentiation） and typical post-industrial economic structure in parallel with an intention to actively participate in reindustrialization and increase the innovativeness of economy. This article searches whether foreign investment stock in a company＇s equity capital provides a stimulus for an industrial change at a micro level （five regions and 12 manufacturing sectors in accordance with statistical classification of economic activities NACE 2 Rev. （Nomenclature generale des Activities economiques dans les Communuates Europeennes） two-digit level） and whether this change contributes to the regional growth. Unbalanced regional growth as a result of reallocation of financial resources among sectors of economic activity and differences in distribution of economic success at a sector     

Mixing oil and water? Using hybrid input-output tables in a Structural decomposition analysis

Input-output studies of energy use frequently adopt the so-called hybrid table, where the rows corresponding to energy sectors are in energy units rather than in monetary units. However, we show that, in structural decomposition analyses, this hybrid approach may induce arbitrary results that depend on the choice of units, rather than on changes in economic structure. This is because an economically meaningless sum of monetary and energy units enters the calculations. Our proposed solution to this problem is based on using a sum of monetary units instead, thus avoiding this attempt to mix oil and water.     

A Spatial Structural Decomposition Analysis of Chinese and Japanese Energy Demand: 1985–1990

This paper proposes a spatial structural decomposition analysis to measure the effects of the changes in intra- and inter-country linkages on the embodied energy demand in the concerned country. For the empirical analysis, we have used the China- Japan inter-country input–output tables for 1985 and 1990, expressed in constant prices of 1990. The empirical results reveal that (1) at least for the period between 1985 and 1990, the effects of the non-competitive input structural changes in China on the primary energy requirements of Japan were negligible, and (2) the contribution of the Japanese final demand shifts on the total change in Chinese primary energy demand was 40 times larger than that of the Chinese final demand shifts on the primary energy requirements of Japan. The Japanese policy makers should concentrate on the energy impacts of the changes in the domestic production structure rather than the changes in the Chinese production structure.     

转型时期制度变迁对我国经济增长影响的实证分析

Analytical Problems in Decomposing the System-wide Effects of Sectoral Technical Change

The disaggregated structure of input–output (IO) analysis makes it very attractive in analyzing technical change. Various authors have applied IO models in comparative static experiments to measure the effects of observed technical changes in individual industries on economy-wide total output (or related primary input) requirements. Less often have researchers performed similar analyses on the effects of changes across all consuming industries in the productive consumption of a sector's output, because of the need to append an external analysis of substitution. Despite the obstacles to joint analyses of sectoral production and cross-sectoral consumption change, its appeal has long been recognized. In this paper, an anomaly in such analyses is presented: the sum of the separate effects of changes in production and changes in productive consumption does not equal the effects of the joint change. A comparative static exercise reveals the root cause of the anomaly: essentially, an index number problem. Empirical analyses are performed across a comprehensive set of US sectors to estimate the range of discrepancies.

Adjustment, Stabilisation and the Analysis of the Employment Structure in Turkey: An Input- Output Approach

The aim of the paper is to examine the effects on employment of the large-scale structural adjustment programme undertaken by Turkey from the early 1980s onwards. In this respect, we particularly analyse how appropriate the choices of factor intensity after structural adjustment programme have been in the domestic production in comparison with the availability of domestic factor endowment. Our findings show that foreign trade in intermediate goods creates extra use of domestic labour, which can be considered as the labour cost of importing intermediate goods. This is the case in the majority of industries in the pre- and post-liberalisation period in Turkey. However, the capacity of using extra labour as a result of importing intermediate goods appeared to have decreased in the post-liberalisation period.

European Technology,Trade and Income Changes for 1975–85: An Intercountry Input–Output Decomposition

This paper refines, develops and applies input–output (IO) decomposition analysis: by providing it with a unique intercountry perspective, by concentrating on explaining income growth, and by systematically separating the effects of trade structure changes from the effects of technology and preference changes. The resulting matrix formula distinguishes six components and is applied to a set of European Community (EC) intercountry IO tables for 1975 and 1985 with 25 sectors and eight EC countries. Because GDP growth is analyzed in nominal terms, macro-economic demand growth is found to be the most important component. The other five components relate to the effects of coefficient changes. Their sizes are smaller, but significant and widely different between sectors and countries, which shows that there is clear potential for effective sector policies.     

Factors driving sectoral and occupational employment changes during the Spanish boom (1995–2005)

Spain's economy grew at a real annual average rate of over 3.5% between 1995 and 2005. Total employment increased by more than five million. This process altered the sectoral and occupational structure of employment. The dynamics of final demand, technology and labour requirements linked to technology and labour market institutions mostly drive shifts in the structure of employment. We analyse their effects and relative weights on private employment growth in an input–output framework, by means of structural decomposition. The analysis of the occupational structure is a novelty. Sectoral and occupational structures of employment are receiving a great deal of attention: the productivity growth and economic prospects of service economies and the debate between skilling and polarization are, respectively, the main issues. This paper provides useful insights on the dynamics of the structure of employment during a process of vigorous job growth.     

Additive Structural Decomposition Analysis and Index Number Theory: An Empirical Application of the Montgomery Decomposition

In recent years, a large number of empirical articles on structural decomposition analysis, which aims at disentangling an aggregate change in a variable into its r factors, has been published in this journal. Commonly used methods are the average of the two polar decompositions and the average of all r! elementary decompositions (Dietzenbacher and Los, 1998 Dietzenbacher, E. and Los, B. 1998. Structural decomposition techniques: sense and sensitivity. Economic Systems Research, 10: 307–323. [Taylor & Francis Online] [Google Scholar], D&L). We propose to use instead the ‘ideal’ Montgomery decomposition, which means that it satisfies the requirement of factor reversal imposed in index number theory. We prefer it to the methods previously mentioned. The average of the two polar decompositions is not ‘ideal’, so that the outcome depends on the ordering of the factors. The average of all elementary decompositions is ‘ideal’, but requires the computation of an ever increasing number of decompositions when the number of factors increases. Application to the example of D&L (four factors) shows that the three methods yield results that are close to each other.     

Challenges of green consumption in China: a household energy use perspective

To encourage economic progress, China's government has been pushing domestic consumption as a substitute for its waning growth in investment and exports. It has also been promoting greener policies for growth, of which green consumerism is a prime component. By examining the economy through the lens of household energy consumption, this paper lays out the challenges the nation must overcome through green consumption. We explore the trends in household energy use and decompose energy used indirectly by households into six factors: changes in total population, urbanization rate, energy efficiency, interindustry input mix, household consumption preferences, and per capita household consumption level. Doing so yields insights into how progress in industrial technology, household income, urbanization, and lifestyles has affected energy use in the production of goods and services used by households. It also offers policy suggestions on how China might guide lifestyle changes to effect green consumption.
