Đổi mới và Các công ty "Năng suất tăng trưởng ở Slovenia Ngược lại với các kết quả tiếp theo, ở đây chúng tôi không phân biệt đối xử giữa sản phẩm và quá trình đổi mới và xem xét bất kỳ hình thức của yếu tố quyết định của tăng trưởng năng suất. | 8 Innovation and Firms Productivity Growth in Slovenia 187 where VA is value added and Emp is employment. In contrast to the subsequent results here we do not discriminate between product and process innovation and consider any form of determinant of productivity growth. Contrary to our expectations no significant positive effects of innovation on labor productivity growth are revealed in the top panel of Table . Moreover small manufacturing firms between 10 and 50 employees even experienced a significant negative treatment effect of innovation on labor productivity growth significant at 10 only . It remains to be seen in the later specification whether this result is robust. One possible explanation for failure to find more conclusive results may be that we are not capturing the relevant growth period. It may take longer than 2 years after the initial innovation for firms to internalize all the benefits of it. To control for this we redefined productivity growth so that we explore the growth in labor productivity between the second and fourth year after the innovation VA VA growth t 4 t 2 1 ln ln Emp t 4 Emp t 2 The bottom panel of Table presents estimates of the average treatment effect of innovation on labor productivity growth between the second and fourth years after the innovation was initially made. By changing the period of observation we hope to capture the effects of innovation on productivity that were not apparent in the first 2 years after the time of innovation. As before we find that innovating firms did not grow significantly faster in terms of productivity than comparable noninnovating firms. We no longer find negative impacts of innovation on productivity growth in small manufacturing firms. Interestingly while a non-significant impact of innovation on productivity growth of manufacturing firms has been expected with respect to our previous OLS results finding non-significant results for services firms is a little more surprising. .
