IT Outsourcing—A Source of Innovation? Microeconometric Evidence for Germany

Does IT outsourcing really influence firms' process innovativeness? We investigate this question with a distinguished view on manufacturing and service sectors. Previous studies suggest firms sourcing out IT services to external service providers are generally more process innovative. Based on a firm‐level data set comprising 1452 firms from the German manufacturing and services sectors, the econometric analysis confirms a positive and significant relationship between IT outsourcing and process innovation activity on an aggregate level. As proposed by our framework of differences between manufacturing and service firms, a more detailed analysis reveals that this positive relationship only holds for services firms.

Servitization across countries and sectors: Evidence from world input-output data

This paper uses the supply tables underlying WIOT data to explore the provision of services by manufacturing. The service shares differ substantially across countries and sectors, while they remain largely stable over time. A latent class analysis assigns broadly defined manufacturing sectors to economy-wide growth models, differentiating between service- and manufacturing-driven models in catching-up and developed economies. Servitization increases with labor productivity. The service intensities in the sectoral production mix are lower in countries with higher manufacturing shares. This holds for both catching-up and developed economies. However, servitization is largely unrelated to productivity and employment growth. We therefore argue that the degree of servitization is contingent on and an attribute of the respective economic model in which a sector operates.     

我国生产性服务业与制造业关系的区域差异研究 ——基于两部门模型

基于两部门模型,分析工业化不同阶段生产性服务业与制造业发展关系的演变,并对影响我国生产性服务业与制造业发展的因素进行分区域分析,结果表明:我国生产性服务业和制造业的发展关系在不同区域存在显著差异,东部地区的制造业与生产性服务业呈现互动发展关系;中部地区的制造业与生产性服务业的产业关联性较弱,尚未形成互动发展的格局;西部地区的制造业不发达,生产性服务业发展缓慢,两者之间的产业关联效应最低。因此,各区域应根据所处的发展阶段和实际情况采取不同的发展策略:东部地区应充分发挥市场作用,明确政府职能,促进制造业和生产性服务业的融合发展;中部地区应加快制造业的转型升级,优化服务业结构,推进制造业与生产性服务业的互动发展;西部地区应跨越重工业化阶段,着力发展轻工业、生态农业和服务业,建设具有西部特色的以中小城市为主、大城市为辅的城市体系。     

A NEW SECTORAL TAXONOMY BASED ON PECUNIARY KNOWLEDGE EXTERNALITIES: KNOWLEDGE INTERACTIONS IN A VERTICALLY INTEGRATED SYSTEM

The paper presents a new sectoral taxonomy that focuses on the existence of non-negligible external effects that derive from user–producer knowledge interactions. These are coupled with intermediate goods transactions, in a system of vertically integrated manufacturing and services sectors. These externalities, the so-called pecuniary knowledge externalities, are the main source of changing technological conditions experienced by downstream producers. A distinguishing feature of the taxonomy lies in its derivation from a particularly dynamic context of changing production functions. The taxonomy is empirically derived, examining effects generated by technological knowledge in a system of intermediate goods transactions and taking into account peculiar characteristics of sectors in European economies. The results allow for a classification of sectors in five groups. An analysis of these classes confirms previous evidence that technological characteristics of sectors across classes differ.     

Sources of Structural Change for the UK Service Industries 1979–84

Over the period 1979 to 1984 the UK economy experienced severe structural change in that the oil and services sectors increased their share of employment and output, whilst the share of manufacturing fell by about 5 percentage points. This paper uses input–output tables for 1979 and 1984 to decompose the changes in output of total marketed services and the component industries into the changes due to price changes and those due to volume changes. The volume changes are, in turn, decomposed into those internal to the service industries, e.g. changes in demand for business services by communication, and those external to the industries, e.g. changes in demand for services by manufacturing. The analysis is done at a 101-industry level with results presented in the paper for the five service industries, Distribution and Catering, Transport, Communications, Business Services and Other Market Services. The paper is intended to give insight into the answers to the following questions: How much of the increase in service output has been due to the reallocation of activities previously done within manufacturing? In what respects were services insulated from the effects of the general recession 1979-812? Has the recent growth in services output been due to more consumers' expenditure and other. final demand or to other factors? The main conclusion is that changes in Input–Output coefficients were very important for structure change in UK services, almost entirely because they dominated the fastest-growing sector, business services.     

Disaggregate productivity comparisons: sectoral convergence in OECD countries

International comparisons of productivity have used exchange rates or purchasing power parity (PPP) to make output comparable across countries. While aggregate PPP holds well in the long run, sectoral deviations are persistent. It raises the need for a currency conversion factor at the same level of aggregation as the output that is compared. Mapping prices from household expenditure surveys into the industrial classification of sectors and adjusting for taxes and international trade, I obtain an expenditure-based sector-specific PPP. Using detailed price data for up to 8 years between 1970 and 1999, I test whether the sectoral PPPs adequately capture differential changes in relative prices between countries. They work well for agriculture and the majority of industrial sectors, but not for most service sectors and for manufacturing sectors that produce differentiated products. Using the most appropriate conversion factor for each industry, productivity convergence is found to be taking place in all but a few industries for a group of 14 OECD countries. The latter results are robust to the base year used for the currency conversion.     

Environmental Kuznets Curves for Air Pollutant Emissions in Italy: Evidence from Environmental Accounts (NAMEA) Panel Data

This paper provides new empirical evidence on delinking and Environmental Kuznets Curves (EKC) for greenhouse gases and other air pollutant emissions in Italy. A panel dataset based on the Italian NAMEA (National Accounts Matrix including Environmental Accounts) for 1990–2001 is analysed. The highly disaggregated dataset (29 production branches, 12 years and nine air emissions) provides a large heterogeneity and can help to overcome the shortcomings of the usual approach to EKC based on cross-country data. Both value added and capital stock per employee are used as alternative drivers for analysing sectoral NAMEA emissions. Trade openness at the same sectoral level is also introduced among the covariates. We find mixed evidence supporting the EKC hypothesis. The analysis of NAMEA-based data shows that some of the pollutants such as two greenhouse gases (CO₂ and CH₄) and CO, produce inverted U-shaped curves with coherent within-range turning points. Other pollutants (SO_X, NO_X, PM₁₀) show a monotonic or even N-shaped relationship. Macro sectoral disaggregated analysis highlights that the aggregated outcome should hide some heterogeneity across different groups of production branches (industry, manufacturing only and services). Services tend to present an inverted N-shape in most cases. Manufacturing industry shows a mix of inverted U and N-shapes, depending on the emission considered. The same is true for industry (all industries, not only manufacturing): although a turning point has been experienced, N-shapes may lead to increased emissions with respect to very high levels of the economic driver. In general, EKC evidence is more pronounced for greenhouse gases. The results suggest that analysis at macro sector (whole industry, manufacturing only and services) can be the most promising approach to future research on EKC.     

THE DRIVERS OF STRUCTURAL CHANGE

The main goal of this paper is to provide an integrated survey of the literature devoted to identifying the drivers of structural change, broadly defined as the process of reallocation of economic activity across the three broad sectors agriculture, manufacturing and services. Using the GGDC 10‐Sector Database, this paper first presents the empirical facts associated with structural change in different regions of the world – that is Europe and the USA, Asia, Latin America, and Africa – then reviews four determinants of structural change: (i) changes in income, (ii) changes in relative (sectoral) prices, (iii) changes in input–output linkages and (iv) changes in comparative advantage(s) via globalization and trade.     

The impact of R&D on factor-augmenting technical change – an empirical assessment at the sector level*

The aim of the paper is to quantify endogenous factor-augmenting technical change driven by R&D investments in a panel of 11 OECD countries over 1987–2007. This paper contributes to the scant empirical evidence on the speed, sources and direction of technical change for various sectors and production factors. Assuming cost-minimization behavior, a CES framework is used to derive a system of equations that is estimated by a GMM system estimator. The estimated factor-augmenting technology parameters show that in most sectors, technical change was labor-augmenting and labor-saving. Statistically significant effects of manufacturing and services R&D were found on factor-augmenting technical change (with the highest R&D elasticities found in the high-tech manufacturing and transport, storage and communication sectors). Whereas ‘in-house’ R&D stimulates total factor productivity, R&D spilled over to other sectors has a capital-augmenting effect accompanied by a higher use of labor. The results of this study provide a starting point for incorporating endogenous factor-augmenting technical change in impact assessment models aimed at broad policy analysis including economic growth, food security or climate change.     

Intersectoral labour reallocations and unemployment in Italy

The Italian labour market, like most European labour markets and unlike the US, shows a greater cyclical sensitivity of the service sector with respect to manufacturing and firing costs higher than hiring costs. This accounts for the negative relationship between sectoral employment shifts and Italian unemployment in the post-war period and, correspondingly, for the pro-cyclical pattern of the Lilien index, in contrast with the US experience.By applying the Lilien index to the Italian context, this paper analyses the relative importance of sectoral regional and national factors in the explanation of changes in industrial structure, and their impact on unemployment. The econometric exercise illustrates that, given the structural features of the Italian labour market, the decline in intersectoral and interregional labour reallocations has significantly contributed to the increase of unemployment in Italy. New hires, the pull of new sectors, sectoral shifts and regional mobility can keep unemployment down, while at the same time maintaining some of the structural features of the “European model” (high employment security and stability).     

Productivity Growth, Efficiency and Outsourcing in Manufacturing and Service Industries

This paper is a survey of recent contributions to, and developments of, the relationship between outsourcing, efficiency and productivity growth in manufacturing and services. The objective is to provide a thorough and up–to–date survey that provides a significant discussion on data, as well as on the core methods of measuring efficiency and productivity. First, the readers are introduced to the measurement of partial and total factor productivity growth. Different parametric and non–parametric approaches to the productivity measurement in the context of static, dynamic and firm–specific modelling are discussed. Second, we survey the econometric approach to efficiency analysis. The issues of modelling, distributional assumptions and estimation methods are discussed assuming that cross–sectional or panel data are available. Third, the relationship between outsourcing and productivity growth in manufacturing and services is discussed. The correspondence between a number of hypotheses and empirical findings are examined. Examples of varieties of relevant empirical applications, their findings and implications are presented. Fourth, measurement of inputs and outputs in manufacturing and services are discussed. Finally, to promote useful research, a number of factors important to the analysis of outsourcing, efficiency and productivity growth in the service sector are summarised.     

Expectations Formation and Business Cycle Fluctuations: An Empirical Analysis of Actual and Expected Output in UK Manufacturing, 1975–1996

Direct measures of expectations, derived from survey data, are used in a Vector Autoregressive (VAR) model of actual and expected output in eight industries in the UK manufacturing sector. No evidence is found with which to reject rationality in the derived expectations series when measurement error is appropriately taken into account. The VAR analysis illustrates the importance of intersectoral interactions and business confidence in explaining the time profile of industrial outputs, examines the mechanisms by which shocks are propagated across sectors and over time and investigates the relative importance of sectoral and aggregate shocks of different types.     

The path to outcome delivery: Interplay of service market strategy and open business models

Firms in a variety of manufacturing sectors as well as the software industry have increasingly embraced services alongside their product portfolios in order to improve financial performance. Yet, the key question “How do service market strategy change and the accompanying business model change interact, and how does their interplay affect value creation?” remains open. Relying on twelve case studies of firms that have shifted towards providing highly advanced services (e.g. outcome-based contracts), theoretical propositions concerning the interplay of market strategy and business model on value creation are derived. The firms studied report two interdependent changes: first, they evolve the market strategy from provision of pure products to provision of services and then outcomes, in order to achieve a better fit with customer needs and to grow their service businesses. Second, they rely increasingly on partners and suppliers to provide new activities that are outside their competence base. This 'open business model' allows them to grow their new service businesses effectively and efficiently. At the same time, however, the shift to a service market strategy requires enhanced accountability to customers and increases the threat of penalties in the case of failure, while reliance on partners and suppliers leads to loss of control over the activity system and increases the threat of failure due to third party dependency. Thus, this paper finds that the success of firms that shift to services and outcomes hinges on their ability to balance the trade-off between increased value (i.e. growth, efficiency and effectiveness) and increased uncertainty associated with service market strategy/open business model interplay.

Structural change and blurred sectoral boundaries: assessing the extent to which knowledge-intensive business services satisfy manufacturing final demand in Western countries

This paper focuses on the vertical integration of knowledge-intensive business services (KIBS) into manufacturing sectors, using a subsystem approach to input–output analysis. It aims at correctly assessing the process of structural change that has occurred in the four main European countries (France, Germany, Italy and the UK) over time (1995–2005). It does not focus on KIBS sectors per se, but on their function as carriers and sources of knowledge which influences the performance of sectors, value chains and clusters across industries and within countries. The analysis shows that KIBS’ contribution to satisfying the final demand of manufacturing is in general largely underestimated; that KIBS vertical integration into manufacturing has increased over time in all the countries investigated except the UK; and that the extent to which manufacturing sectors outsource to KIBS is significantly affected by their technological intensity.     

Sectoral Shocks and Metropolitan Employment Growth

In this paper, we study the sources of industry employment growth in each of five metropolitan statistical areas (MSAs). The objective is to understand the relative importance of aggregate disturbances versus local sectoral shocks in generating observed employment fluctuations at the MSA level. The empirical evidence presented in this paper derives from structural vector autoregressions (SVARs), estimated for each of the five MSAs. Estimations use monthly employment data covering nine one-digit industrial categories for the period 1951:1–1999:8, as well as two variables that capture the influences of aggregate (i.e., national) shocks on MSAs. We find that within-MSA industry shocks explain considerably more of the forecast error variance in industry employment growth than do aggregate shocks. Sectoral shocks account for between 87 and 94% of the 36-month-ahead forecast error variance. Among individual local sectors, shocks to MSA-specific government, manufacturing, and service sector employment growth are the predominate sources of variability.     

Economic Structure and Local Growth: France, 1984–1993

For 52 industry sectors and 42 services sectors, this paper tests how the local economic structure (local sectoral specialization and diversity, competition, average size of plants, and total employment density) affects the 1984–1993 employment growth of 341 local areas. These areas entirely and continuously cover the French territory. The impact of the local economic structure differs in industry and services. In industrial sectors, local total employment density, competition, and plant size always reduce local growth. Sectoral specialization and diversity have a negative impact on growth, but also increase the growth of a few sectors. Service sectors always exhibit negative specialization effects and positive diversity effects. Competition and plant size have a negative impact and density a positive one, but exceptions are observed for some sectors.     

Knowledge,diversity and entrepreneurship: a spatial analysis of new firm formation in Great Britain

This paper argues that the diversity of a region's knowledge stock and its balance between knowledge-based manufacturing and services are both important determinants of variations in the rate of new business formation across spatial areas. An empirical study of new firm formation across 408 local unitary authorities and districts in Great Britain over the period 2001–2007 is presented, taking explicit account of the interactions amongst spatial units through an econometric modelling procedure involving maximum likelihood spatial models and alternative spatial weighing matrices. The results indicate that both related and unrelated knowledge diversity have a positive impact on the rate of business formation, whilst aggregate local economy-wide industrial and ethnic diversity has no impact; the division of the knowledge stock between services and manufacturing is also significant, with services having a positive impact on new business formation in contrast to a negative impact for high-technology manufacturing. There is also some support for the view that low wages and economic inactivity constrain new business formation, whilst a competitive regional environment has a positive impact. The results imply that polices should be aimed at creating a diverse set of knowledge-based industries rather than specialization in a narrow range.

Enhancing the green efficiency of fundamental sectors in China’s industrial system: A spatial-temporal analysis

Due to sectoral interactions in the economy, the overall green efficiency (GE) of China’s industrial system relies heavily on fundamental sectors that contribute substantial energy to the supply chain production of other sectors but shows low sectoral GE. For the three fundamental sectors in China’s industrial systems, namely the smelting and pressing of nonferrous metals (SPNFM), the processing of petroleum, coking, and nuclear fuel (PPCNF); and the manufacturing of nonmetallic mineral products (MNMMP), we employed a three-stage data envelopment analysis (DEA) model to measure GE in the fundamental sectors in 30 provinces from 2010 to 2015. We then adopted a stochastic frontier analysis (SFA) model to evaluate the influence of technological innovation (TI), industrial agglomeration (IA), environmental regulation (ER), and intraindustry competition (IC). The results showed that GE in the three fundamental sectors varied spatially. Specifically, TI promoted GE in MNMMP, but the effect was not obvious in the SPNFM and PPCNF sectors. Moreover, ER had positive impacts on GE in the fundamental sectors. The effects of IA and IC on GE in the fundamental sectors varied in direction and strength. After eliminating the impacts of environmental effects and statistical noise, the real GE in the three fundamental sectors varied significantly compared to the comprehensive GE. Policy opportunities for enhancing GE in the fundamental sectors mainly lie in region-specific policy and regulations that avoid a “one-size-fits-all” governance approach.
