how advanced are italian regions in terms of public eservices
DESCRIPTION
The study aims at providing evidence on regional differences in the diffusion of ICT in the public sector in Italy, with a focus on different types of public e-services (eGovernment, eHealth, eEducation and Intelligent Transport Systems). Data are ob-tained by merging four different surveys carried out by Between Co. (2010-11) and Istat - Italy’s National Bureau of Statistics (2009). We pursue a three-fold objective. First, we attempt to overcome the prevailing attitude to consider the various domains of public e-service provision as separate from one another. In other words, measuring the progress of digital government requires a holistic view to capture the wide spectrum of public e-services in different domains (e.g. local and national administrative procedures, transportation, education, etc.) and the different aspects of service provision (not just e-readiness or web interactivity, but also multi-channel availability and take-up). Second, we shall tackle a major drawback of existing statistics and benchmarking studies of public e-services, which are largely based on the count of services provided online, by including more sophisticated indicators both on quality of services offered and back office changes. Third, we develop a sound, open and transparent methodology for constructing a public eServices composite indicator based on OECD/EC-JRC Handbook. This methodology, which incorporates experts opinion into a Data Envelopment Analysis, will allow us to combine data on different e-service categories and on different aspects of their development, and will enable us to define a ranking of Italian regions in terms of ICT adoption and public e-service development.TRANSCRIPT

Aims and scope • Providing evidence on regional differences in the
diffusion of public eServices in Italy with a focus on
– different types of public eServices: beyond a monodimensional analysis based on e-gov diffusion
– not only front- but also back-end issues
– different channels for service delivery
• Providing a sound, open and transparent methodology for constructing a public eServices composite indicator based on OECD/EC-JRC Handbook
![Page 3: How advanced are Italian regions in terms of public eServices](https://reader033.vdocument.in/reader033/viewer/2022060110/555b07e7d8b42a64398b5085/html5/thumbnails/3.jpg)
Composite indicators (CI)
A composite indicator is formed when individual indicators are compiled into a single index, on the basis of an underlying model of the multi-dimensional concept that is being measured (OECD Glossary of statistical terms)
• Composite indicators are increasingly used by statistical offices, international organizations (e.g. OECD, EU, WEF, IMF) and academic researchers to convey information on the status of countries in fields such as the environment, economy, society or technological development: Cox et al., 1992; Cribari-Neto et al., 1999; Griliches, 1990; Huggins 2003; Grupp and Mogee 2004; Munda 2005; Wilson and Jones 2002; among others
• The proliferation of these indicators is a clear symptom of their importance in policy-making, and operational relevance in macro and micro economics in general (Granger, 2001)

Pros and cons of CI
Pros Cons
Can summarize complex or multi-dimensional issues in view of supporting decision-makers.
Easier to interpret than trying to find a trend in many separate indicators.
Facilitate the task of ranking countries on complex issues in a benchmarking exercise.
Can assess progress of countries over time on complex issues.
Reduce the size of a set of indicators or include more information within the existing size limit.
Place issues of country performance and progress at the centre of the policy arena.
Facilitate communication with general public (i.e. citizens, media, etc.) and promote accountability.
May send misleading policy messages if they are poorly constructed or misinterpreted.
May invite simplistic policy conclusions. May be misused, e.g., to support a desired
policy, if the construction process is not transparent and lacks sound statistical or conceptual principles.
The selection of indicators and weights could be the target of political challenge.
May disguise serious failings in some dimensions and increase the difficulty of identifying proper remedial action.
May lead to inappropriate policies if dimensions of performance that are difficult to measure are ignored.

Existing CIs in public eServices field
• are specific to a single domain / type of eService
• employ simple equal weighting as standard aggregation method (with a few exceptions)
• do not assess results with Uncertainty or Sensitivity Analysis (UA – SA)
Critical remarks have been raised against EC eGovernment bechmarking index. Criticism is mainly focused on theoretical framework, indicators chosen, aggregation scheme adopted (Bannister, 2007; Bretschneider et al, 2005; Fariselli & Bojic 2004; Goldkuhl & Persson, 2006; Jansen, 2005)

What is new in our methodology for a Public eServices CI
1. Expanding the scope of the analysis of eServices diffusion – A holistic view to capture the wide spectrum of public e-services in different domains
(in our case: eGov, eEducation,eTransportation) and the different aspects of service provision (e.g. technical and organizational change within PAs and new service implementation)
2. Improving the quality of the framework – Using more sophisticated indicators both on quality of services offered and back
office changes – Robustness check of the framework / classification of indicators
3. Developing a sound, open and transparent methodology – Asking experts to assess the importance of basic indicators – Real benchmarking: measuring the distance from the efficiency frontier – Tracing back the contribution of the different aspects of eService diffusion (e.g. back-
and front-end issues) to intermediate and final indices – Checking the robustness of results by reiterating the calculation of the CI with 12
other different methods (Uncertainty Analysis)

Public eServices CI - our framework -
• Existing theoretical frameworks are mainly focused on eGovernment and based on stage models implying linear progression (Lee, 2010)
[i.e. from stage 1 = input/eReadiness to stage n = outcome] – academic papers (Andersen & Henriksen, 2006; Hiller & Belanger, 2001; Layne & Lee,
2001; Moon, 2002; Siau & Long, 2005; Scott, 2001; West, 2004) – institutional reports (Center for Democracy & Technology, 2002; Grant & Chau, 2005;
United Nations, 2001, 2003, 2005, 2008) – private consulting firms reports (Accenture, 2003; Deloitte Research, 2000)
• Most available frameworks can hardly be applied to the construction of our CI
“Too often composite indicators include both input and output measures. […] However, only the latter set of output indicators should be included if the index is intended to measure innovation performance”
(OECD/EC-JRC Handbook on Constructing CIs, p.6)

Basic indicators selection & robustness check of the framework
• An initial set of 30 indicators were assigned to each “pillar” (e-service domain) and “sub-pillar” (aspect of innovation activity being considered)
• 8 Principal Component Analyses and KMO tests were performed (1 for each sub-pillar) to check the consistency of the framework
• We applied the eigenvalue-one criterion [only one eigenvalue should exceed the unity (Kaiser, 1960)] to make sure that indicators in each sub-pillar share no more than 1 underlying dimension
• 6 indicators that did not pass this test have been discarded

Steps for computing CI
• What is the relative importance of each Basic Indicator?
• How to aggregate the Basic Indicators in order to measure the level of development of each region in eEducation, eGovernment and eTransportation?
• How to calculate the final score?
• What is the robustness level of the results we obtained?

Gathering expert opinion through Budget Allocation (BA)
What is BA? Experts are given a “budget” of N points, to be distributed over a number of individual indicators by “paying” more for those indicators whose importance they want to stress. (Moldan and Billharz 1997)
Phases: 1. Selection of experts for
the evaluation
2. Allocation of budget to indicators
3. Calculation of weights
(a) Randomly selected from the corresponding authors of 751 top-journal articles reviewed by Arduini and Zanfei (2011). => 100 papers extracted.
(b) Also included 15 participants at the 1st International EIBURS-TAIPS Conference that present papers on eServices diffusion
An on-line questionnaire was administered. Experts were asked to allocate a 100 points budget within each sub-pillar, so that the total number of indicators to evaluate is < 4 (Bottomley et al., 2000)
![Page 17: How advanced are Italian regions in terms of public eServices](https://reader033.vdocument.in/reader033/viewer/2022060110/555b07e7d8b42a64398b5085/html5/thumbnails/17.jpg)
Results of BA
No expert consensus on the appropriate set of weights (Mean coef of var among indicators = 0.4426)
– High variation / disagreement
– No single pair of expert suggesting similar weights
We must choose a statistical method to calculate weights, while trying not to waste the information provided by the experts

Combining Benefit of the Doubt (BoD) approach with expert opinion
• BoD is a method for data aggregation based on Data Evelopment Analysis (DEA) (Melyn & Moesen, 1991, Cherchye et al., 2007)
• BoD advantages – objective statistical/mathematical approach – it measures “efficiency” => compares a region’s performance
with a benchmark in a multi-dimensional space – the algorithm tends to use those indicators where the region
shows better performances • no other weighting scheme yields higher composite indicator value
(political acceptance) • reveals policy priorities / past choices • embeds concern for regional diversity
• BoD + Expert constraint (Cherchye et al., 2008)
– We impose that the use of each indicator is limited by expert opinion. The MIN (MAX) use of an indicator corresponds to the MIN (MAX) weight it has received from the experts
![Page 19: How advanced are Italian regions in terms of public eServices](https://reader033.vdocument.in/reader033/viewer/2022060110/555b07e7d8b42a64398b5085/html5/thumbnails/19.jpg)
Indicator = ratio of the distance between the origin and the actual observed point and that of the projected point in the frontier
Source: rearranged from Mahlberg and Obersteiner (2001)
Through DEA we estimate an efficiency frontier used as a benchmark to measure the relative performance of regions
Benefit of the Doubt (BoD) approach through Data Envelopment Analysis (DEA)
In our case, CIs of the 3 pillars
are the distance from an ideal
case with 100% on all basic
indicators

The “pie-share” constraint
• Applying only the bounding and the non-negativity constraints may allow for extreme scenarios (Cherchye L., 2008)
– If a region’s value of one sigle indicator dominates those of other regions, that region will get the max score of 1 even if it has very low values in the other indicators
• We introduce a pie-share constraint that incorporates expert opinion (Wong and Beasley, 1990)
Li = lower bound = MIN expert weight from BA
Ui = upper bound = MAX expert weight from BA
![Page 22: How advanced are Italian regions in terms of public eServices](https://reader033.vdocument.in/reader033/viewer/2022060110/555b07e7d8b42a64398b5085/html5/thumbnails/22.jpg)
Results
• In the following slides the resulting scores and ranks from the constrained optimisation are presented
• The score:
– represents a measure of a region’s efficiency compared to the benchmark (the “ideal case”)
– is the sum of the pie-shares of each indicators, that we have grouped toghether at a sub-pillar level (aspect of innovation activity being considered)

Results per pillar (1/4) scores
• The highest variation in the scores can be found in eTransportation domain, while eEducation performances seem not to vary much
• eGov results for Lombardy, Piedmont and Province of Trento are lower than expected.
– This is probably due to the high proportion of very small municipalities
![Page 25: How advanced are Italian regions in terms of public eServices](https://reader033.vdocument.in/reader033/viewer/2022060110/555b07e7d8b42a64398b5085/html5/thumbnails/25.jpg)
Results per pillar (2/4) rankings
• The 3 rankings differ substantially
=> significantly different regional patterns
– Very high variations in the ranking for the Province of Trento and Lazio. Medium-high variation for Lombardy, Calabria, Campania
– Other regions show a more homogeneous approach to public eServices development which is characterized by different trajectories of diffusion
• High scores for EMR, TOS, BOZ | medium scores for VEN MAR PIE | low scores SIC, BAS
![Page 26: How advanced are Italian regions in terms of public eServices](https://reader033.vdocument.in/reader033/viewer/2022060110/555b07e7d8b42a64398b5085/html5/thumbnails/26.jpg)
Results per pillar (3/4) pie shares
Tracing back pillar results through “pie shares”
• eEducation - Pie shares are more or less fixed, i.e. all regions use the same “mix” of indicators to maximize their score, under the expert constraint. This is due to quite similar relative values of each indicator and to the specific combination of bounds that experts have imposed
• eTransportation – Pie shares are flexible, so each region chooses its own set of weights revealing the areas where investments have been made
• eGovernment – intermediate case
![Page 27: How advanced are Italian regions in terms of public eServices](https://reader033.vdocument.in/reader033/viewer/2022060110/555b07e7d8b42a64398b5085/html5/thumbnails/27.jpg)
Results per pillar (4/4) pie shares
• Indicators related to ICT diffusion in internal processes and organizational changes have a major role in computing the final score of all public e-services categories (eEdu, eGov and eTra)
• The importance of back office re-organization through ICTs has emerged in the literature on the development of organizations, which has emphasized the essential role of skills that characterize the different components of an organizational structure (Fountain and Osorio-Ursua, 2001; Fountain, 2003; West, 2005; Helfat et al., 2007)
![Page 28: How advanced are Italian regions in terms of public eServices](https://reader033.vdocument.in/reader033/viewer/2022060110/555b07e7d8b42a64398b5085/html5/thumbnails/28.jpg)
1. Normalization: MIN-MAX, where MAX is the region with the highest score
2. Final aggregation through Geometric Mean – the marginal gain of an increase
in a low score is much higher than in a high score

Uncertainty Analysis (UA)
• UA is a robustness assessment of a CI (Saltelli et al, 2008)
• The uncertainties in the development of a composite
indicator will arise from some or all of the steps in the construction line (Saisiana et al, 2004)
(a) selection of subindicators (b) data selection (c) data editing (d) data normalization (e) weighting scheme (f) weights' values and (g) composite indicator formula (e) level of aggregation where the methodology applies

Results of UA
• CI final scores based on BoD weights are among the best possible results a region can obtain
• Good robustness level, especially for top and bottom ranked regions
– 13 regions out of 19 show only a 0/1/-1 shift compared to the median rank
![Page 35: How advanced are Italian regions in terms of public eServices](https://reader033.vdocument.in/reader033/viewer/2022060110/555b07e7d8b42a64398b5085/html5/thumbnails/35.jpg)
Conclusions 1/2
From a methodological point of view
– BoD approach combined with BA is an effective way incorporate both regional choices and expert judgment into CI
– Geometric aggregation gives higher scores to regions showing a more balanced eServices diffusion among the 3 domains
– Uncertainty analysis on rankings shows high robustness levels for top and bottom ranked regions

Conclusions 2/2
Main findings and implications from our analysis: – ranking reflects hierarchy of regions in terms of per capita
income and industrial development: current development of public eServices does not seem to correct unbalances between regions lagging behind and frontrunners
– high heterogeneity in terms of mix of e-service proficiency: need for a regional differentiation of e-service promotion policies ;
– there is more cross regional variation in terms of eEducation and eTransportation than in terms of eGov: human capital formation and mobility enhancing are bound to be the real distinctive assets of regions
