Induced effects of smart food/agri-systems in Japan: Towards a structural analysis of information technology

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.     

ICT and economic growth in Sub-Saharan Africa: Transmission channels and effects

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.     

Technical efficiency and use of information and communication technology in Spanish firms

The literature concerned with the relationship between performance and information and communications technology (ICT) is usually focused on the ICT investments. This paper shows that it is the level of use of ICT within organisations, with preference as regards the expenses of ICT, which is responsible for the effect on performance. A general sample of 2255 Spanish companies has been used. Firms’ performance is measured as technical efficiency, which is determined by a data envelopment analysis (DEA), in which special attention is paid to the problem of the outliers. Finally, the analysis of the level of use of ICT is focused on a key area of the organisations, the supply chain, which affects the technical efficiency of the firms analysed. Results show that there is evidence of a positive effect of the use of ICT on technical efficiency. This effect is especially notable at intensive use levels in activities related to operations/manufacturing, purchasing or sales.     

External knowledge search,innovative performance and productivity in the Korean ICT sector

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.     

How information and communication technology drives (routine and non-routine) jobs: Structural path and decomposition analysis for China

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.     

Impact of information and communication technologies on agricultural households’ welfare in Benin

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.     

Measurement and characterisation of the Digital Divide of Spanish regions at enterprise level. A comparative analysis with the European context

Until now, a reduced number of research is observed on the adoption and use of ICTs in enterprises and on the digital divide (DD) between them at regional scale in Europe. What is meant by DD are the differences in the levels of digital development of the enterprises; being the digital development the degree of adoption and use of ICTs and e-commerce by the firms. The aim of this piece of work is to characterise and measure the DD in the Spanish regions and those in the countries of the European Union based on the data of their enterprises with more than 10 employees which have used ICTs. The methodology is developed in the following stages: 1) Construction of a synthetic index of digital development (Enterprise Digital Development Index –EDDI-) for countries in the EU and Spanish regions. The production of this index is carried out based on the factors obtained with the factor analysis (FA) with the aim of identifying the key variables which define the different EDDI components. These variables come from the “Community survey on ICT usage and e-commerce in enterprises” of Eurostat. 2) Classification of Spanish regions into the groups of European countries with a similar level of EDDI components based on the discriminant analysis. Those groups are previously obtained by using cluster analysis. And 3) Comparative analysis of the DD between the Spanish regions and those in countries of the EU based on EDDI components and the identified groups. The study provides a synthetic index (EDDI) at European scale comprising 3 dimensions which permits obtaining: i) a ranking from more to less digital development of countries and regions permitting the measurement of the DD among them is established; and ii) a typology of European countries and Spanish regions is defined according to the 3 dimensions of EDDI. The main results of this piece of work show that the Spanish regions at enterprise level: i) are in a medium or higher level of digital development than their European counterparts, presenting, furthermore, a lower DD between them in relation to what happens in European countries; ii) stand out for having a higher digital inclusion than European countries in the ICTs related to infrastructures of internet access and for the interaction with the public authorities; and iii) have a digital development deficit in the integration of ICTs for e-commerce.     

Standard essential patents and global ICT value chains with a focus on the catching-up of China

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.     

Analyzing the relationships between information technology, inputs substitution and national characteristics based on CES stochastic frontier production models

This research examines four interrelated issues at the country level: the value of information technology (IT), inputs substitution and complement, the complementarity phenomenon created by IT and national characteristics, and the productivity paradox, jointly and critically from a global perspective, using the so-called productive efficiency as the performance measure. To that end, we develop the three-factor constant elasticity of substitution (CES) stochastic production frontier model and apply it to a set of panel data from 15 countries over the period 1993–2003, along with the traditional two-factor CES models, within the one- and two-equation frameworks. In the two-equation setting, six national characteristics are selected as the contributing factors of the productive efficiency. The findings include: (i) the value of IT as measured by the productive efficiency is duly recognized: (ii) the productivity paradox is found to be absent from the production process in a majority of developed and developing countries considered, rejecting the existing argument that the paradox exists only in developing economies but does not exist in developed countries; however, the developed countries have used IT capital in their production systems more productively efficiently than the developing nations; (iii) traditional capital (non-IT capital), traditional labor, and IT capital are not pairwise substitutable, contrary to the notion that they are pairwise substitutable at the firm level; (iv) constant returns to scale, as commonly assumed, are not supported by the data; (v) different national characteristics affect a country's output (represented by gross domestic product or GDP) and its productive efficiency differently; and (vi) the complementarity phenomenon is observed in most of the countries (developed and developing) under study.
