CBI Regional Trends Survey Analysis: Objectives
• Are there significant differences between regions in the way in which innovation responds to its determinants?
• Are the effects of one region’s activities on another observable, and do these linkages vary across regions?

CBI Regional Trends Survey: Innovation Question – Data Source
• The data source is the CBI-Experian Regional Trends Survey.
• Quarterly data on innovation and other variables, with the innovation data dating from 1990.
• Data allows us to observe changes in innovation over time and across regions.

CBI Regional Trends Survey: Regional Data
Individual responses are aggregated to the regional level using a regional weighting matrix of value added weights for six industrial groups, and three size groups, with the simplification that the size distribution is assumed similar across the UK.
![Page 5: CBI Regional Trends Survey: Innovation Question Analysis Ciaran Driver, Tanaka Business School Imperial College, University of London Christine Oughton,](https://reader036.vdocuments.us/reader036/viewer/2022062619/5518ba5955034638098b466e/html5/thumbnails/5.jpg)
Innovation question (17a):
“Do you intend to authorise more or less expenditure in the next twelve months than was authorised in the past twelve months on product and process innovation?”
These “balance” replies are interpretable as rates of growth of the underlying variable (Driver and Urga 2004)

• Innovation through “Market Research and Design”
Thus it is a broad innovation indicator
What does the Innovation Question Capture?

• Dominance of national-level training
• In regions that have high levels of general qualifications (A-levels or degrees), own-region training is not significant

Caveat 2
•Basic equation potentiallymis-specified in that innovation experiences a downward step break around 1999
•Introducing the regional training variable removes the need for a break dummy
•But is regional training truly exogenous?
![Page 23: CBI Regional Trends Survey: Innovation Question Analysis Ciaran Driver, Tanaka Business School Imperial College, University of London Christine Oughton,](https://reader036.vdocuments.us/reader036/viewer/2022062619/5518ba5955034638098b466e/html5/thumbnails/23.jpg)
CBI Regional Trends Survey Analysis: Objectives - Recall
• Are there significant differences between regions in the way in which innovation responds to its determinants?
• Are the effects of one region’s activities on another observable, and do these linkages vary across regions?
![Page 24: CBI Regional Trends Survey: Innovation Question Analysis Ciaran Driver, Tanaka Business School Imperial College, University of London Christine Oughton,](https://reader036.vdocuments.us/reader036/viewer/2022062619/5518ba5955034638098b466e/html5/thumbnails/24.jpg)
Effects of regional innovation on unit cost
• A regional model of unit cost
• Is national or regional innovation more important?
![Page 25: CBI Regional Trends Survey: Innovation Question Analysis Ciaran Driver, Tanaka Business School Imperial College, University of London Christine Oughton,](https://reader036.vdocuments.us/reader036/viewer/2022062619/5518ba5955034638098b466e/html5/thumbnails/25.jpg)
• Does innovation affect unit cost with a lag?
• We use the survey data to form a dependent variable of change in unit cost
• Change in unit cost is then regressed on:
• Lagged innovation intentions
• Survey-based capacity utilisation
A regional model of unit cost: innovation effects

• Innovation in the CBI survey mainly seems to be associated with capital investment
• A reasonable first-cut model is obtained with a lagged dependent variable and the index of business optimism
• There is similarity across regions to the extent that the optimism elasticities can not be shown to be different across the 10 main regions
Conclusions_1
![Page 32: CBI Regional Trends Survey: Innovation Question Analysis Ciaran Driver, Tanaka Business School Imperial College, University of London Christine Oughton,](https://reader036.vdocuments.us/reader036/viewer/2022062619/5518ba5955034638098b466e/html5/thumbnails/32.jpg)
• National training affects innovation strongly but the variable may be non-stationary
• When national training is excluded, regional training is significant (at least at 10%) in all but one region
Conclusions_2
![Page 33: CBI Regional Trends Survey: Innovation Question Analysis Ciaran Driver, Tanaka Business School Imperial College, University of London Christine Oughton,](https://reader036.vdocuments.us/reader036/viewer/2022062619/5518ba5955034638098b466e/html5/thumbnails/33.jpg)
• Innovation intentions at national level affects perceived change in unit cost in each region
• There is little support for regional innovation affecting unit cost
• An exception is for the panel of regions with higher general education where both regional and national innovation variables are jointly significant or significant when entered singly
Conclusions_3
