Advancements in productivity in the digital economy constitute an important engine for economic growth. What drives productivity dynamics in the information and communication technology (ICT) sector? This study examines the productivity dynamics of ICT firms across countries from the perspective of corporate balance sheets. We study the effects of intangible assets and leverage on productivity growth using firm-level panel data from five industrialized countries. We find that intangible assets positively affect the total factor productivity in the ICT sector. The positive effect of intangible assets on total factor productivity growth is larger for ICT manufacturing firms than for ICT service firms. We also find that leverage has a positive relationship with total factor productivity development in the ICT sector. In addition, our empirical results substantiated that productivity is catching up to the technological frontier. Furthermore, larger firms and/or younger firms generally show higher total factor productivity growth than their peers. Economies of scale are more prominent in the ICT service sector than in the ICT manufacturing sector. Our findings contribute to the understanding of cross-country productivity dynamics in the ICT sector at the firm level in the digital economy.  相似文献

Despite significant progress in the empirical analysis of the impact of information and communication technology (ICT) on economic growth, previous studies have not empirically examined the mechanisms by which ICT hinders or expands economic growth. The specific aim of the present study was to identify the transmission channels through which ICT contributes to economic growth. The examined channels included; openness, FDI inflows, education, domestic investment, political institution, and inflation. The study employed the panel-corrected standard errors (PCSE) and system two step system GMM techniques on a sample of 44 countries in Sub-Saharan Africa (SSA) over the period 2004–2020. Using an ICT composite index, the causal mediation analysis identified that ICT contributed directly to growth, as proposed by the growth theories. Furthermore, the same analysis identified; domestic investment, openness, and education as crucial variables through which ICT penetration indirectly promoted per capita growth in the SSA region. The robustness of this result was verified using a variety of tools. The present findings suggested that the current efforts to expand ICTs in Sub-Saharan Africa should be continued since this sector has a considerable indirect impact on promoting economic growth.  相似文献

A comprehensive exploration into the routine/non-routine job implications of information and communication technology (ICT) is crucial for tackling routine-replacing technological change challenges in the digital era. To this end, we propose an integrated input-output (IO) analytical framework to detangle the intertwined relations between ICT and non-ICT sectors, and further incorporate structural path analysis (SPA) and structural decomposition analysis (SDA) to examine the extent to which and how ICT sub-sectors drive the formations and changes of embodied routine/non-routine jobs in ICT. An empirical study using China's national IO tables from World Input-Output Database and the matched occupational employment data derived from 2000 and 2010 Population Census is conducted. We find that China's ICT growth over 2000–2010 has not led to a decline in jobs, which still holds true for both ICT manufacturing and ICT service, as well as for routine/non-routine jobs. We also find an increase in the embodied employment share of non-routine relative to routine jobs. The typical paths “source sector → (intermediate sector) → ICT final demand” generate many routine/non-routine jobs, which are primarily lied in the zero and first rounds. The decomposition results show that the declining sectoral routine/non-routine job coefficients drives the decline of both ICT embodied routine and non-routine jobs (especially the former), which is completely offset by the rising final demand of ICT. The proposed integrated IO analytical framework could also be applied to other indicators and extended to multi-country/region analysis.  相似文献

Patents, standards and their combination, standard-essential patents (SEPs), are important in the information and communication technology (ICT) sector, in particular in mobile communication. We argue that SEPs are relevant in macroeconomic development and estimate the effect of a country's SEP portfolio on its value-added trade in global ICT value chains (GVC). We find that SEPs retain a higher share of value-adding domestically and that absorptive capacity is needed to join GVCs. China entered the SEP market late and is catching up rapidly. The trade effect of SEPs on China is different from that on matured economies because of the initially low value of its SEPs.  相似文献

Estimation of the employment effects of changes in capital investment is a standard tool in public policy debates. Typically, such predictions are based on employment multipliers derived from Input–Output analysis. In this paper, we measure the employment effects of changes in capital investment in the U.S. information sector by econometrically estimating an “employment multiplier” from historical data. The estimated multiplier is 10 information sector jobs for each million dollars in expenditure, and perhaps 24 new jobs per million dollars invested across the entire economy. Employment multipliers derived from the Input–Output methodology average about 16 jobs per million, but the multiplier includes jobs outside the information sector. Including employment spillovers, our estimates suggest the multipliers from Input–Output models are plausible. We also note that information sector jobs have substantially higher median earnings than the private sector average, so the economic significance of changes in information sector employment are greater than might first appear. Our findings may be useful in debates over changes in industry regulation that could affect investment.  相似文献

China's financial industries started the process of marketization only two decades ago, but by 2017 its financial technology or fin-tech sector had taken half of the global market. The exponential diffusion of information and communication technologies (ICTs) in Chinese financial contexts have generated new organizational structures and socio-political relations that have the capacity to change China's position in the world economy. Drawing upon the sociological concept of institutionalization, this paper examines how the Chinese state has integrated ICT diffusion in its formal policies and its informal rules in China's financial development since 1991. Further, it addresses the political and socio-economic consequences of these developments. Based on the analyses of government documents and sources, trade journals, and statistic data from business databases, this paper divides the Chinese institutionalization of financial technologies into three stages and identifies the primary actors and paradigms for ICT diffusions in each stage. ICT diffusion has been constitutive but also disruptive to the existing financial policies, instrumental to the commercialization of state-owned banks, and has gradually transformed into a set of formal and informal rules accepted by a network of professionals, corporations, and government agencies. The institutionalization of ICT diffusion has engendered the continuous adjustment of financial policies and propelled innovations in China's financial economy.  相似文献

The Japanese government decided to promote “smart society” in the 5th Science and Technology Basic Plan. The purpose of this research is to evaluate the effects of information and communication technology (ICT) in smart society by input-output analysis using the food industry and agriculture as examples. We define food production and agricultural activities utilizing ICT as a smart food-agri system, and try to analyze the effect of such a system on the economy as a whole. As a result, we confirmed that such a system has a large economic ripple effect on information sectors. At the same time, through these analyses, (1) we redefine information goods and service sectors, (2) we describe the new management sectors that are using these goods and services, but are not currently independent businesses, and (3) we clarify new industrial structure that exists in “smart society” using ICT.  相似文献

This study aims to examine the impact of inventions, measured by the number of new patents, on economic growth. Specifically, we focus on patents in the ICT sector for a global sample of 43 economies, comprising 26 advanced and 17 emerging market economies in the period 1998 to 2016. We use a two-step system GMM to control for potential endogeneity in the data. Our results are threefold. First, total patents have mutually causal effects with economic growth, but there is no evidence of an impact of total patents on manufacturing sector growth. At the same time, ICT patents have a unidirectional causal impact on both, overall economic growth, and the growth of services and manufacturing. Second, the impact of total patents on economic growth is stronger in advanced economies. At the same time, ICT patents have a positive significant impact on the growth of advanced economies and a negative significant effect on the growth of emerging economies. Third, in the long-run, ICT patents have a positive significant impact on economic growth, while total patents do not.  相似文献

The aim of this paper is to present a quantification approach for the calculation of the ICT sector's structural effects in the economy, focusing on the case of Greece. We construct a composite sector using a hypothetical extraction methodology based on the most recent Greek input-output table and structural business statistics at the national level. Our framework builds on the formal definition of the ICT sector provided by OECD and includes two distinct sub-components, ICT manufacturing and ICT services. In the second stage of this study, we explore the production linkages among ICT services, ICT manufacturing and the rest of the Greek industries using input-output-based and network analysis-based metrics that build on the intermediate transactions of an expanded input-output table of the Greek economy that includes the two sectors. Our empirical findings suggest that the total ICT sector has a major contribution to the Greek economy in terms of GDP and employment, but this is driven mainly by the ICT services component. We further identify that ICT services are more integrated in the Greek production network compared to ICT manufacturing, but their production linkages are underperforming in terms of meaningful contribution to the activity of the rest of the sectors. These results reflect the low integration of digital technologies and can be further embedded in a discussion on the ICT deficiencies of the Greek economy and the need for targeted regulatory and financial interventions.  相似文献

Information technologies are very important to transform the agricultural sector and improve economic performance. Nevertheless, does the use of information and communication technologies (ICT) improve agricultural households' welfare? To answer this, the study used a nationally representative household survey, the Comprehensive Food Security and Vulnerability Analysis (CFSVA) carried out in 2017 in Benin. The survey covered a sample of 15 000 households, however, the analysis focused on the 6502 agricultural households. An endogenous switching regression model was employed to control for selection bias and endogeneity issues. Results indicated that the use of ICT increases households' consumption expenditure by 89.6%. This implies that the use of ICT improves agricultural households' welfare. Other variables that affect agricultural households’ welfare include age, marital status, farm size, access to credit, ownership of livestock, membership in a farmer-based organization, and region of residence. Furthermore, the decision to use ICT in agricultural households depends on the level of education, age, sex, marital status, farm size, access to credit, ownership of livestock, membership in a farmer based organization, and location. These findings suggest that policies that promote the use of ICT are key to improving welfare of agricultural households in Benin. These policies must consider demographic, socio-economic, and institutional characteristics of households.  相似文献

This article conjectures that the legacy industry-specific regulation that has governed the telecommunications sector for a long time is in basic conflict with the dynamics and product innovations that characterize the modern information and communications technology (ICT) sector. Reasons for the failure of legacy regulation to promote product innovations are explained and proposals for alternatives, such as deregulation and regulatory reform are discussed. Both regulation and competition policy are more difficult for ICT than for other sectors. Therefore both, regulation and competition policy may need reforms in order to deal with new problems. The most drastic and most realistic alternative to legacy-type regulation remains deregulation and a move to competition policy. Symmetric regulation, smart regulation, quasi-Coasean approaches and subsidies all have some limited applicability to specific situations, but are all associated with complications that have to be resolved, while competition policy is a comprehensive alternative. Last-mile access and gatekeeper access are analyzed as two main areas of legacy regulation, which are in danger of being exported to other ICT areas. Such exports may negatively affect the dynamics of the ICT industry. Rather than being exported, legacy regulations should be reduced in order to enhance product innovations.  相似文献

The adoption of information and communication technology (ICT) has made it possible to experience high levels of visibility, control and connectivity across the entire supply chain. However, in road transport logistics, wireless ICT applications like cellular networks, Wi-Fi, UMTS, 4G and WiMax have not entirely solved reliability and connectivity problems due to difficulties associated with limited range, scalability and security. This paper examines the feasibility of using a vehicular network technology, dedicated short range communication (DSRC), in a multimodal logistics environment as means of providing enhanced visibility and connectivity using a secure access architecture. The secure access architecture is necessary to provide a high degree of security to the detailed visibility involving road haulage feeding port operations using a centralised port service.  相似文献

The Internet has changed the global economic landscape. In particular, the fast-changing Information and Communication Technology (ICT) has directly led to a far-reaching impact on the production and operation of firms. Many previous studies have discussed the relationship of ICT and the total factor productivity (TFP) of firms, but failed to reach a consistent conclusion. This paper, based on the data of Chinese listed manufacturing firms from 2010 to 2019, explores the impact of ICT on manufacturing firms' TFP and its mechanism, and concludes that ICT have positive correlation with the TFP of manufacturing firms. According to the estimated results of this paper, TFP will increase by about 1.8 % for every 1 % of additional ICT investment. Through channel analysis, this paper finds that the positive effect can be achieved through the following four channels: cutting information search costs, enhancing information processing capabilities, reducing internal capital misallocation, and promoting R&D efficiency. This paper is a supplement to research on firm TFP, provides new micro-evidence for exploring the relationship between ICT and TFP of manufacturing firms, and brings important implications for understanding the role of ICT in firm production activities.  相似文献

Despite policy initiatives aimed at promoting female access to jobs, the information and communication technology (ICT) professions have traditionally been largely monopolised by men. Segregation, gendered stereotypes and environmental factors have a clear impact on educational and professional choices, as well as on working conditions. The spread of ICT to all economic activities has meant that ICT specialists are now to be found everywhere, not only in the ICT sector where many stereotypes related to technical jobs persist. This work aims to analyse the gender wage gap and discrimination in ICT professions, with the emphasis on how working in an ICT-intensive industry might affect that situation. The study uses the Spanish Earning Structure Survey data for 2014, and applies wage decomposition techniques to the wage distribution. The results show that female ICT professionals face unfavorable working conditions, especially in highly qualified jobs and in ICT-intensive industries.  相似文献

Information and communication technologies (ICTs) like CRM, ERP and Intranet are considered important for creating competitive advantage. Despite their rapid deployment rates, only a few studies mainly from the information technology (IT) and engineering literature have been devoted in uncovering the factors that influence the diffusion of new information technologies within an organization. Similarly, empirical studies regarding the impact of ICT diffusion on organizations are strikingly limited. In an attempt to fill this research void, the present study examines the implementation of ICT tools within marketing-related and non-marketing-related functions. By testing a number of hypotheses using structural equation modeling, the authors conclude that the antecedents and consequences of ICT diffusion in these functions vary. Their findings provide the foundation for a more thorough examination of both intraorganizational diffusion of ICT tools as well as their impact on organizations.  相似文献

In recent years, Korea’s Information and Communication Technology (ICT) industry has grown rapidly. The prosperity of the ICT industry has brought growing recognition that rising productivity and innovative performance have made major contributions to ensuring competitive advantage in international markets. In this context, recent studies stress the importance of external knowledge for improving both innovative performance and productivity. This paper empirically investigates the effects of firms’ external knowledge search behavior on their productivity as well as their innovative performance in the Korean ICT manufacturing sector. Based on firm-level data from the Science and Technology Policy Institute (STEPI), this study indicates that incremental innovation and productivity are both related to external knowledge search.  相似文献

The sequence of events leading up to the upcoming auction of 1800 MHz spectrum in India has led to the auctions acquiring an extraordinary significance for the future of the Indian mobile industry. A key feature of the auction design proposed by the regulator TRAI is the benchmarking of the reserve price of 1800 MHz to the price of 2100 – 3G spectrum revealed in the 2010 auction. In the context of the low number of LTE devices available and the fragmentation in the 1800 MHz band, this paper proposes reducing the duration of spectrum holding to ten years (from the current level of twenty years), and calibrating the reserve price of 1800 MHz with its value with GSM deployment. An economic model is used to compute the value of startup and incremental 1800 MHz spectrum. The estimated values are shown to differ from the value of 2100 MHz spectrum at a pan-India level and also in their distribution across circles. A new set of reserve prices are computed based on the estimation. The estimated values are also shown to be close to the AGR-adjusted price revealed in the 2001 auction. A reserve price based on the 2001 auction is also provided. Concomitant features of the auction are suggested to give coherence to the auction design.  相似文献

Information work is defined from a behavioural perspective, as the manipulation of information, when performed by workers. A set of activities characterizing information work are identified, drawing on Blooms Taxonomy as the reference source. Using this measure, the 1977 Dictionary of Occupation Titles was content analysed to identify those occupations which could be behaviourally classified as information work. 40% of all occupations were determined to be informational in work behaviour. These occupations were found across all sectors, although they were concentrated in the service sector. Many occupations, old and new, have taken on an informational character.  相似文献

This paper investigates the cointegration and causal relationships between Information and Communication Technology (ICT) and economic output in Australia using data for about five decades. The framework used in this paper is the single-sector aggregate production function, which is the first comprehensive approach of this kind to include ICT and non-ICT capital and other factors to examine long-run Granger causality. The empirical evidence points to a cointegration relationship between ICT capital and output, and implies that ICT capital Granger causes economic output and multifactor productivity, as does non-ICT capital.  相似文献
