Green innovation plays a substantial role in creating new products and services, as well as in reducing environmental impacts and promoting the efficient use of resources and materials. This study investigates the linkage between green innovation and research and development (R&D) practices inside and outside firms over time; it also explores types of external partners. The results show that internal and external R&D efforts enhance the activities of green innovation. However, the external partner is an important factor, whereas cooperation with competitors could help firms in general affairs not related to competition.

RESUMENEn el presente artículo se lleva a cabo un modelo de análisis de la incidencia de las características inherentes al trabajo sobre la satisfacción laboral. El contraste empírico tiene su origen en la Encuesta de Calidad de Vida en el Trabajo del año 2010 (Ministerio de Trabajo e Inmigración de España), siendo la metodología aplicada una regresión stepwise. Las variables independientes que se han considerado en el modelo de la satisfacción laboral fueron, por orden de inclusión y explicación : motivación, actividad, organización del trabajo, salario, jornada, valoración de los superiores, estabilidad, desarrollo personal, vacaciones y permisos y posibilidad de promoción. Se han obtenido como resultado todos los coeficientes de regresión positivos y significativos, siendo la bondad del modelo aceptable en la medida en que las variables independientes se derivan únicamente de características de la organización.PALABRAS CLAVE | Expectativas, motivación, organización, satisfacción laboral, rendimiento. Labour and Immigration, Spain), and the applied model is the stepwise regression. The independent variables which explain the labour satisfaction are by importance: motivation, activity, labour organization, wage, working day, boss valuation, stability, personal development, holidays and permissions, and promotion possibilities. Results show that all the regression coefficients are positive and significant and the goodness of the final model is satisfactory because the independent variables are referred only to the organization characteristics.

ABSTRACT This paper determines a model to analyze the effect of the job-related features on the labour satisfaction. The empirical contrast uses the Quality of Labour Life Survey corresponding to the year 2010 (Ministry of

We analyse the effect of innovation on technical progress in Spanish manufacturing firms by identifying and explaining how the following innovation factors affect technical progress: research and development (R&D) activities and expenditures, patents, innovations in products and in processes, internal organisation of innovation, outsourcing R&D activities, public R&D funding, external relationships of innovation and different ways of external collaboration for innovation. We focus on how firm behaviour and structure drive these innovation factors. Our results are based on multiple regression analyses using firm-level data from 2010. We show that innovations in product, processes and R&D activities (especially external R&D activities) are more likely to improve the productivity of Spanish manufacturing firms. In addition, the activities related to the internal organisation or the external collaboration for innovation generates a higher productivity level. This positive effect is bigger when a firm collaborates with universities and/or technology centres and employs recent college graduates, especially those with degrees in science, engineering or technology.
