#### 3.1.2 Business Sectors  
The data contains 45 categories of industry sectors (Table 3) for the contracts, which exceeds our analysis scope. To find the important ones, we investigate both the value and the quantity of contracts in each sector (see the table below). Six sectors are in the top ten for both value and quantity: (1) construction work, (2) office and computing machinery, equipment and supplies except furniture and software packages, (3) architectural, construction, engineering and inspection services, (4) medical equipment, pharmaceuticals and personal care products, (5) business service: law, marketing, consulting, recruitment, printing and security, (6) health and social work services. The construction work sector of ranks first for both value and quantity.  
From Table 4, we can see that number of observations is 234,071 in total, but missing values occur in some variables. About 9% of the contracts are green under our selection standards, and 79% applied an open bids procedure (OPE). The proportion of product contracts and service contracts are 36% and 49%, respectively; the remaining 15% is for work. Forty-four percent of contracts are under GPA and a very small number of contracts are funded by EU or are electrical. In our sample, central purchasing body awards only 5.6% of the contracts and 2.9% are joint procurement. On the aspect of tenderers, 42% contracts have SME tenderers providing an offer, and the average number of awarded SMEs in one contract is 2.57. In addition, only 6% of the contracts are awarded to a group bidder, and the average number of offers and awards are 3.87 and 3, respectively. What is more, construction work, medical products, and construction services are the top three sectors for contract quantities, accounting for 14%, 10%, and 8.2%, respectively.
