This paper examines the determinants of eco‐innovation strategy in Spanish manufacturing firms. Using panel data of 3,201 Spanish firms for the period 2008–14, we specify a dynamic random probit model controlling for sample selection. The empirical results confirm that public regulations and R&D efforts encourage firms to place eco‐innovation activities among their strategic priorities, although subsidies are not found to be a distinctive driver. Furthermore, we find that eco‐innovation is highly persistent at the firm level, past eco‐innovation behavior being clearly of key importance in explaining the current state of a firm's eco‐innovation orientation. In contrast, market factors are not found to be a key driver for eco‐innovative firms.

The concept of the circular economy (CE) is currently gaining impetus as a way to move towards sustainable, low‐carbon, resource‐efficient, and competitive economies. However, despite the potential benefits of CE activities, their implementation remains relatively rare. We use a cross‐sectional survey of European small and medium‐sized firms (SMEs) to identify the main barriers firms face to promote the CE, focusing specifically on the following: those related to a lack of resources (human and financial) and capabilities (expertise) and those related to the regulatory framework (administrative procedures and the costs of meeting the regulations). Our results indicate that it is the complexity of administrative/legal procedures and the costs of meeting regulations/legal standards that constitute the most significant barriers, whereas the lack of human resources is also perceived to be an obstacle by firms engaged in CE activities. Those obstacles may be considered revealed barriers, and it is only when the firms become involved in these activities that they actually perceive them. Furthermore, when we consider the breadth of CE activities, administrative procedures and regulations once again emerge as the most significant obstacles. Finally, we stress the need to distinguish between different CE activities given that the perception of barriers differs substantially across these activities. Firms undertaking a disruptive innovation redesigning products and services to minimize the use of materials are more likely to perceive all barriers as important. However, firms implementing such activities as minimizing waste, replanning energy usage, and using renewable energy only perceive those obstacles related to administrative procedures and regulations.

Although environmental innovation studies have traditionally focused on manufacturing firms, the distinctive features of eco‐innovation activities carried out by service firms require special attention. Using the Spanish Commumity Innovation Survey (CIS), this paper determines which are the main drivers of undertaking eco‐innovation and investigates the similarities and differences between service and manufacturing firms within the five sub‐groups of services (supplier dominated, scale intensive physical networks, scale intensive information networks, science‐based, and others). The results confirm that the main eco‐innovation triggers are similar—technological push factor orientation (internal R&D and persistence) and firm size—while the impact of market pull factors and public environmental legislation differ within the services sub‐groups. In addition, we find a high degree of heterogeneity within service firms. In contrast to traditional service firms, those in the groups involving R&D activities, information networks, and scale‐intensive physical networks exhibit intensive eco‐innovation performance and show a high level of green indicators.
