In most OECD countries, between 50% to 80% of large enterprises cooperate for product and/or process innovation with some partner(s). These percentages are twice as high as those of firms with less than 250 employees, for which shares of cooperating firms are between 20% and 40%. Mexico is the only exception, with a percentage of SMEs indicating some type of cooperation for innovation (29.2%) slightly higher than Mexican large firms (25%).
