Innovation in R&D service firms: evidence from the UK

Research and Development (R&D) service firms make significant contributions to innovation in other businesses. The extant literature considers these firms a homogenous sub-group of Knowledge Intensive Business Service firms (KIBS). The objective of this study is to investigate how R&D service firms innovate and the variety of innovation practices within these firms. Employing data from semi-structured interviews with senior managers from 32 UK-based R&D service firms, we suggest that there are two different modes of innovation: in the first mode, R&D service firms innovate similarly to KIBS whose innovation is ad-hoc in nature and driven by customers’ requests; another group of R&D service firms innovate like New Technology-based Firms (NTBFs) relying more on structured in-house R&D activities.     

Innovation and productivity in family firms: evidence from a sample of European firms

ABSTRACT

Using firm-level data, we estimate the returns to R&D investments for a sample of European manufacturing firms over the period 2007–2009. Results confirm that R&D efforts are positively related to productivity regardless of firm type (family or nonfamily firms). Additionally, we find that family firms invested more in R&D than nonfamily firms, but the returns to their R&D investments are low, emphasizing that they have a lower capacity to translate R&D investments into economic gains.     

How enterprise strategies are related to innovation and productivity change: an empirical study of Japanese manufacturing firms

This study analyzes the total factor productivity of 1067 Japanese manufacturing firms. In production estimation, we employ the directional distance function and Luenberger productivity indicator. Research and development strategy survey data are used to analyze the determinant factors related to improvements in innovation and productivity. Our results indicate that increasing technology and knowledge through a ‘black box’ process is related to an increase in productivity. Furthermore, the protection and management of production knowledge and expertise is a valid method of increasing global technical change.     

The productivity trend in Iran Evidence from manufacturing firms

Iran has been experiencing slow growth for the past ten years. Using plant‐level information, we show that on average firm‐specific productivity in manufacturing sectors declined at the rate of 2.6% annually, while large top decile firms experienced a modest growth in productivity between 2005 and 2011. We decompose this trend and find that within‐plant variation is its main driving force while the between firms and industries component is insignificant. We test several alternative explanations that may contribute to these negative trends. We show that the subsidy reform had a negative effect, while privatization seems to have had no effect. Private management not affected productivity growth, while firm size is associated with higher productivity growth. Also, we find that productivity growth decreases with the energy intensity of the firm. We also find that R&D expenditures significantly increase productivity growth, while the R&D sales ratio is about 0.5% in manufacturing sectors, which is about one‐fifth of the world average. A one‐percent point increase in R&D expenditures increases productivity growth by 0.5%.     

Evidence on the impact of R&D and ICT investments on innovation and productivity in Italian firms

Both research and development (R&D) and information and communication technology (ICT) investment have been identified as sources of relative innovation underperformance in Europe vis-à-vis the USA. In this article, we investigate the R&D and ICT investment at the firm level in an effort to assess their relative importance and to what extent they are complements or substitutes. We use data on a large unbalanced panel data sample of Italian manufacturing firms constructed from four consecutive waves of a survey of manufacturing firms, to estimate a version of the CDM model of R&D, innovation, and productivity [Crépon–Duguet–Mairesse 1998. Research, innovation and productivity: An econometric analysis at the firm level. Economics of Innovation and New Technology 7, no. 2: 115–58] that has been modified to include ICT investment and R&D as the two main inputs into innovation and productivity. We find that R&D and ICT are both strongly associated with innovation and productivity, with R&D being more important for innovation, and ICT investment being more important for productivity. For the median firm, rates of return to both investments are so high that they suggest considerably underinvestment in both these activities. We explore the possible complementarity between R&D and ICT in innovation and production, but find none, although we do find complementarity between R&D and worker skill in innovation.     

R&D spillovers and productivity: Evidence from U.S. manufacturing microdata

This paper deals with the estimation of the impact of technology spillovers on productivity at the firm level. Panel data for American manufacturing firms on sales, physical capital inputs, employment and R&D investments are linked to R&D data by industry. The latter data are used to construct four different sets of `indirect' R&D stocks, representing technology obtained through spillovers. The differences between two distinct kinds of spillovers are stressed. Cointegration analysis is introduced into production function estimation. Spillovers are found to have significant positive effects on productivity, although their magnitudes differ between high-tech, medium-tech and low-tech firms.

Innovation and productivity in agricultural firms: evidence from a country-wide farm-level innovation survey

ABSTRACT

The literature on the links between innovation and productivity at the firm level in agriculture is almost nonexistent. In this paper, we analyze the factors behind the innovation effort of farms and the impact that innovation effort has on farm’s productivity, exploiting a unique farm-level agricultural innovation survey carried out in Uruguay. The results indicate that farm size, cooperation with other agents to perform R&D, the education of the owner of the farm, the participation of foreign capital and the existence of links with other organizations, in particular scientific, horizontal and vertical ones, are positively correlated with innovation effort. Public and private financial support are not clearly linked with innovation effort. The innovation effort has a positive effect on farm’s productivity. Some heterogeneities across industries in agriculture are found.     

R&D and productivity: evidence from large UK establishments with substantial R&D activities

ABSTRACT

We use Office for National Statistics' micro data for large UK establishments in the production industries in the period 1997–2008 to study the relationship between their productivity and the presence of substantial R&D activities, either at the production unit itself, or at other UK reporting units owned by the same enterprise group. We estimate that total factor (revenue) productivity is on average about 14% higher at the establishments which have substantial R&D themselves, compared to those with no R&D. Among the establishments with no R&D themselves, we estimate that productivity is on average about 9% higher at those which belong to enterprise groups which do have substantial R&D elsewhere in the UK in the same sub-sector. For the establishments with substantial R&D themselves, we also estimate a significant positive relationship between current productivity and past R&D expenditure using dynamic specifications which allow for both establishment-specific ‘fixed effects’ and a serially correlated error component.     

Knowledge spillovers,absorptive capacity and total factor productivity in China’s manufacturing firms

Applying the stochastic frontier framework, this study explores the diffusion and absorption of technological knowledge in China’s manufacturing firms, based on a panel of more than 10,000 local and foreign-invested firms over the period 1998–2001. Our empirical approach allows us to distinguish between technological progress (TP) and technical efficiency (TE) in analysing whether R&D, exports and the presence of foreign direct investment simultaneously enhance TP through knowledge spillovers in a single framework and whether different types of domestic absorptive capacity moderate external knowledge spillovers in relation to TE. The results show that there are positive inter-industry productivity spillovers from R&D and foreign presence, whereas evidence of intra-industry productivity spillovers from FDI to Chinese firms is less robust. We find evidence that absorptive capacity is one of the key determinants to quantitatively explain intra-industry differences in productivity of local Chinese firms. The findings have important policy implications.     

The productivity effects of local R&D outsourcing: the moderating role of subsidiary mandate and internal R&D

This study examined the moderating effects of two kinds of internal R&D (parent R&D and subsidiary R&D) on the relationship between local R&D outsourcing and subsidiary productivity as internal R&D challenges the collaborative relationships in the local environment. Due to the specific feature of a subsidiary mandate, we further investigate whether two distinct kinds of internal R&D have different moderating effects between exploitation-oriented subsidiaries and exploration-oriented subsidiaries, based on a sample of longitudinal data set of 263 Taiwan-based manufacturing subsidiaries over the period 2006–2009. The empirical results show that for exploitation-oriented subsidiaries parent R&D plays a significant and negative moderating role on the impact of local R&D outsourcing based on local collaboration, while a positive moderating role is observed with parent R&D and subsidiary R&D for exploration-oriented subsidiaries.     

Impact of patenting on firms' performance: an empirical investigation based on manufacturing firms in India

The study aims to estimate the impact of R&D expenditure and patenting on the performance of firms using productivity, profitability and Tobin's q ratio as the performance indicators. The study uses firm-level data of 489 high- and medium-technology firms during the period of 2000–2010. We employ relatively a new source of data particularly in the context of India, firm-level patent granted, that has not been explored earlier. The study finds that firms patenting result in productivity improvement of firms, whereas R&D expenditure does not. The study further finds the evidence of positive impact of patenting on financial performance of firm with significant differences between foreign and domestic firms.     

Measuring knowledge intensity in manufacturing industries: a new approach

This article presents the methodology and results for measuring the knowledge intensity of manufacturing industries based on the knowledge-related characteristics of their workforce. The measures link information from the Occupational Information Network project (from the US Department of Labor) and the Occupational Employment Statistics (from the Bureau of Labor Statistics) to produce industry-specific knowledge intensity measures. The new measures overcome the main issues posed by the industry-average R&D share in total sales variable, often used as a proxy for knowledge intensity in the literature.     

Modes of international activities and the innovativeness of firms: an empirical analysis based on the Japanese National Innovation Survey for 2009

We quantitatively examine the factors which account for differences in innovation output depending on the mode of international activities, employing the innovation accounting framework proposed by Mairesse and Mohnen [2001. To be or not to be innovative: An exercise in measurement. NBER Working Paper No. 8644. Cambridge, MA: National Bureau of Economic Research; 2002. “Accounting for Innovation and Measuring Innovativeness: An Illustrative Framework and an Application.” American Economic Review 92 (2): 226–230]. We find that internationally engaged firms use more innovation inputs and generate more innovation outputs. Firms with R&D establishments abroad show the best innovation performance. A significant part of the higher innovation performance of internationally engaged firms can be explained by their greater intra-firm knowledge spillovers, R&D intensity, perceived competitive pressure, and proximity to basic research. However, more importantly, our innovation efficiency analysis suggests that engagement in international activities increases the sales amount of innovative products though it does not necessarily raise the probability that a firm successfully develops a new product or process.     

Services liberalization and productivity of manufacturing firms

Employing a unique database of Ukrainian firms in 2001–07, we use the external push for liberalization in the services sector as a source of exogenous variation to identify the effect of services liberalization on total factor productivity (TFP) of manufacturing firms. The results indicate that a standard deviation increase in services liberalization within a firm is associated with a 9.2 percent increase in TFP. The effect is stronger for firms with high productivity, bringing about a reallocation of resources within an industry. Industry‐level results show that the effect of reallocation on industry productivity is almost as strong as the within‐firm effect. The dynamic interaction of services liberalization and TFP through the investment channel reinforces the effect. The effect is robust to different estimation methods and to different sub‐samples of the data. In particular, it is more pronounced for domestic and small firms.     

The impact of R&D subsidy on innovation: evidence from New Zealand firms

This study examines the impact of government subsidy through R&D grants on innovation output for firms in New Zealand. Using a large database that links administrative and tax data with survey data, we find that R&D grants have a stronger effect on more novel innovation (e.g. applying for a patent or introducing new products to the world) than on incremental innovation (e.g. any product innovation) and that larger, project-based grants are more effective at promoting innovation than smaller, non-project-specific grants. There is little evidence that R&D grants have differential effects between smaller (<50 employees) and larger firms.     

Impact of firm size and industry type on R&D efficiency throughout innovation and commercialisation stages: evidence from Korean manufacturing firms

Technological innovation through R&D is a critical element in enhancing and fostering firm performance. In particular, measurement of R&D efficiency throughout the innovation and commercialisation stages is important. However, almost of R&D efficiency-related studies assumed that R&D is a single stage. This study aims at analysing relative efficiency scores throughout the stages of the R&D process using a two-stage data envelopment analysis (DEA) model with a sample of 1039 Korean manufacturing firms. Based on our preliminary results, this study was extended by comparing subsample groups categorised by firm size and industry type. The key findings include: (1) firms show imbalanced R&D efficiency throughout the two stages and (2) R&D efficiency is different by firm size and industry type. The empirical results and findings may assist policy- and decision-makers to enhance R&D efficiency at the firm level. Moreover, introduction of the two-stage DEA model and comparative analysis methods to firm-level data contributes to scholars.     

Research and development and labour productivity: do high-tech firms exhibit labour- or capital-saving technical change?

Employment and output in the advanced technology sectors have generally exhibited above-average growth for more than two decades. While this industry accounts for a relatively small share of total employment, the majority of private sector research and development (R&D) expenditures in the US is concentrated within seven sub-sectors. However, little attention has been paid as to whether high-tech productivity exhibits Hicksian capital or labour ‘savings’ bias or tendency to displace either factor input over time. Biased technical change can occur as economies transition between growth regimes. An augmented production function is employed to analyse the additional impact of R&D activity on firm-level labour productivity. A panel data set comprised of high-tech firms located across the advanced economies, China and India from 1990 to 2013 is used in the analysis. Labour-saving technical change was present across the advanced technology sectors and most countries. The expanded models of labour productivity that used fixed effects with lagged regressors confirmed the prior results as well as finding that R&D per employee, relative R&D intensity and firm market share contribute to firm-level labour productivity growth across countries and sectors. Additional support was found for diminishing returns to scale but not for R&D spillover effects.     

Relationship lending and innovation: empirical evidence on a sample of European firms

This paper investigates the impact of relationship lending on innovation (the probability to innovate and the intensity of innovation). Using a unique dataset providing detailed information on bank–firm relationships across European firms, we relate different proxies of relationship lending (soft information, long-lasting relationships, number of banks and share of the main bank) to innovation. We find a very strong and robust positive effect of ‘soft-information-intensive’ relationships, a less robust positive effect of long-lasting relationships and a negative effect of credit concentration as measured by the number of banking relationships. We also find that ‘soft-information-intensive’ relationships reduce credit rationing for innovative firms, while long-lasting relationships seem to favour innovation via other relational channels. These results raise some concern on the impact of screening processes based on automatic procedures, as those suggested by the Basel rules, on firms' capability to finance innovative activities in Europe.     

Mapping research on R&D,innovation and productivity: a study of an academic endeavour

ABSTRACT

This paper accounts for the development of the academic endeavour to determine the firm-level relationship between investments in R&D and productivity. The impact of 28 highly cited publications within this line of study is investigated using a combination of bibliometric techniques and citation function analysis. We show how the attention paid to this line of research broadens and deepens in parallel to the diffusion of innovation as a research theme during 2000s. Our findings also suggest that the attraction of scholarly attention is driven by combination of broadening interest in the central research question under study and boundary-pushing methodological contributions made in the key contributions.     

Determinants of R&D in knowledge-intensive business services firms

Research and development (R&D) is a key factor enabling firms to gather information, create knowledge and innovate. Although often seen as the preserve of goods-producing sectors, knowledge-intensive business services (KIBS) in particular also engage in R&D. In this paper, we are interested in understanding the determinants of R&D in KIBS. We address this question by exploring factors connected to R&D in KIBS, with attention to whether it is connected with internal capabilities or to establishments' openness. We show that KIBS' R&D is associated with internal capabilities, and that recourse to external R&D is part of a strategy of openness that complements internal capacity. We also suggest that KIBS's own view of R&D is aligned with R&D in the goods-producing sector, leading establishments in non-technological KIBS sectors to under-report R&D.
