The purpose of this paper is to investigate the effect of financial constraints on innovation in developing countries. It also examines how the effect of financial constraints varies by sector and with main firm characteristics such as size and age.

The study utilizes matched firm-level data from two sources; the World Bank Enterprise Survey and the Innovation Follow-Up Survey. From 11 African countries, 4,720 firms have been included in the sample. A recursive bivariate probit model is used.

The result shows that financial constraints adversely affect a firm’s decision to engage in innovative activities and the likelihood to have product innovation and process innovation. The results point out that the extent of the adverse effect of financial constraints on innovation differs across the sectors, firm size and age groups. A firm’s innovation is also explained by firm size, R&D, cooperation/alliance, the human capital of the firm, staff training, public financial support and export. At last, the probability of encountering financial constraints is explained by firms’ ex ante financing structure, amount of collateral, accounting and auditing practices and group membership.

Managers should strengthen the internal and external financing capacity to reduce financing constraints and their adverse effect on innovation.

A pending policy task for African leaders is to design and evaluate reforms that reduce the adverse effects of financial constraints on innovation.

This study contributes to the existing literature on financing of innovation by examining how and to what extent financial constraints affect innovation across various sectors, size and age groups.

The purpose of this paper is to investigate how firms in developing countries finance innovation. Notably, the study seeks to investigate whether innovative firms exhibit financing patterns different from those of non-innovative ones. It also examines the effect of financing sources on firm’s probability to innovate.

The study utilizes firm-level data from the World Bank Enterprise Survey. From 28 African countries, 11,173 firms have been included in the sample. A statistical t-test is used for two independent samples and logistic regression models.

The results show that innovative firms, specifically innovative small- and medium-size firms exhibit financing patterns different from non-innovative peers. Further analysis indicates that there is no statistically significant difference between the financing patterns of innovative and non-innovative large firms. In Africa, innovation is mostly financed using internal sources and bank finance. Equity finance and bank finance have shown a higher effect followed by internal finance, finance from non-bank financial institutions and trade credit finance on firms’ probability to innovate.

The management of innovative firms should reduce dependency on short-term and retained earning financing and increase the use of long-term instruments improve innovation performance.

A pending policy task for African leaders is to design and evaluate reforms to create a strong financial sector that willing to support the innovation process.

This study contributes to the existent literature on finance of innovation by examining how firms finance innovation activities in developing countries. This study provides evidence on how innovative firms exhibit financing patterns different from non-innovative ones from developing countries.
