This paper analyzes the impact of innovation on the performance of Rwandese manufacturing firms, using data from a 2006 World Bank survey. Key findings indicate that product innovation is directly linked to process innovation, and that international quality-recognition significantly influences financial performance, while engagement in innovation does not guarantee such recognition. The study recommends public support for research and development to enhance financial outcomes for these firms.

Innovation and Firms’ Performance in the Rwandese Manufacturing Industry.

A firm Level Empirical Analysis


By:
Etienne Ndemezo1, Charles Kayitana2, Angelique Dukunde3 and Jean Bosco Ndikubwimana4

Abstract

The main objectives of this paper is (i) to determine factors that support engagement in innovative
activities by Rwandese manufacturing firms; (ii) to assess effects of innovation decision on
innovation performance of Rwandese manufacturing firms; and (iii) to evaluate impacts of
innovation performance on financial performance of Rwandese manufacturing firms. To address
these two objectives, we used a structural multistage framework as proposed by Crepon et al.
(1998). Data used are from the 2006 enterprise survey conducted by the World Bank in Rwanda
and referenced as ‘ID RWA_2006_ES_v01_M_WB’. This study resulted in three main outcomes:
(i) product innovation is linked directly to the process innovation, meaning that firms which engage
in process innovation introduced new or improved products on the market; (ii) innovation output,
here the ‘international quality-recognition’, is not linked to the firm engagement in innovation. It
is linked to the use of technology licensed from foreign firms; (iii) the ‘international quality-
recognition’ is the main determinant of firm’s financial performance. Consequently, in order to
boost manufacturing firms’ financial performance a public assistance in Research and
Development to Rwandese manufacturing is recommendable.
