Q2. What are the future works in "Assessing the implementation of sustainable public procurement using quantitative text-analysis tools: a large-scale analysis of belgian public procurement notices" ?
In this part of the paper the authors discuss the findings in relation to the literature and offer venues for future research. Further research into the implementation of SPP and the differences between actual and perceived SPP is thus necessary. Further research into the drivers and barriers of the different types of SPP is therefore necessary to see if and how the implementation of the other types of SPP can be increased. Further research is thus necessary to examine and explain the relationship between SPP and budget.
Q3. How much of the GDP of the European Union was spent on works, goods, and services?
In the European Union, the general government expenditure on works, goods, and services (excluding utilities and some concessions) was approximately 13.3% of the GDP of 2017 (DG GROW, 05 November 2019).
Q4. What is the main reason why public procurement is so powerful?
Because of its sheer size, public procurement has the potential of being a very powerful policy tool to tackle societal and environmental issues (Grandia & Meehan, 2017), such as the decrease of long-term unemployment, improvement of working conditions, and prevention of climate change (Grandia, 2017; Preuss, 2009).
Q5. How many folders were removed from the dataset?
The 106 folders that contained public procurement notices from 2017 were removed from the dataset too, as they were only for January of that year.
Q6. How many notices were included in the analysis?
As the previous analysis showed that the notices with annex(es) paid considerably more attention to SPP than notices without annex(es), the subsequent analyses are limited to the 20% (28,452) notices containing one or more annexes to increase validity.
Q7. How many public procurement notices were published between 2011 and 2016?
To provide an overview of the actual implementation of SPP and its subcategories and identify patterns therein the authors analysed more than 140.000 public procurement notices that were published between 2011 and 2016 using text-mining techniques.
Q8. Why do the notices vary slightly in the analysis?
Due to missing values in background characteristics provided in the .xlm files, the number of notices per analysis can vary slightly.
Q9. What are the frequently identified subcategories of SPP?
If the authors zoom in at the level of the sub-subcategories (table 3) it becomes apparent that environmental friendliness in general4 and waste are the most frequently identified SPP subcategories.
Q10. How many responses did Renda et al. get to the implementation of SPP?
The response rate of the 2012 EU report on the implementation of SPP in the EU27 (i.e. Renda et al., 2012) was for example a mere 4%.
