Abstract
This paper describes the role of R&D and analyse its impact on productivity in the Czech economy in a CDM model. Four CIS waves (2001, 2003, 2006, and 2008) were used in the CDM model. The estimated low innovation input elasticity around 9 % describes the Czechs as poor innovators in the EU. This economy was a developing country until 2006 and we have observed a substantive FDI inflow since 1998. Multinationals have a higher sales share now and are an essential part of the economy. Multinationals engage less in innovation, but innovating MNEs spend more on R&D per employee and appropriate more from their innovated goods. The FDI inflow was a form of innovation wave. Innovation output is an important determinant for boosting productivity among SME’s. Public support had positive effect on innovation intensity; however, no additional effect on innovation output.

Notes
For justification of basic research—see Arrow (1962).
There are neoclassical theories of Romer (1986) and Lucas (1988). There are also competing Schumpeterian theories of Grossman (1993), Aghion and Howitt (2005), and others. There are Evolutionary theories of Nelson (1982), and Dopfer (2005). End eventually complexity science theories (path dependence) of David (1975) and Liebowitz and Margolis (1995).
The National Innovation Strategy (Government Resolution No. 207 of 24 March 2004) and National Innovation Policy of the Czech Republic for 2005–2010 (Government Resolution No. 851 of 7 July 2005) defined state support opportunities and proffered areas of research.
European patent office (EPO) patents, there are about 10 million inhabitants in the Czech Republic. Patent are count in Fractional count, inventor’s country, priority date.
During last 3 years this firm had non-zero sales from innovated products and services and non-zero R&D expenditures in one of these areas: Intramural and external R&D, new equipment, new knowledge, training, advertisement and costs related to introduction of goods to the markets, and other expenditures related to introduction of new products and processes. These expenditures are associated with product, process, organizational, or marketing innovation and they resulted in new to the firm innovation.
Not all models are specified to the number of employees. Some are not normalized, i.e. plain innovation sales variable is used.
CIS data—Innovation survey (TI), Firms’ data—The annual statement of economic entities in selected production sectors (P5-01), R&D data—Annual Report on research and development (VTR 5-01). Representativeness of data samples is provided by the CZSO surveys are carried out according to the State Statistical Service (No. 89/1995 Sb.). A detailed description of data and questionnaires can be found here: http://apl.czso.cz/pll/vykazy/pdf1. The CIS data analysis was possible at CERGE—EI.
Hampering factors refer to barriers, which prevents a firm to innovate or innovate more (lack of information, skilled personnel, technology, finances, high costs, and prior innovation). Demand pull factors refer to information sources, which a firm use to market analyses and possible innovation projects. There are important information sources inside the firm, and outside the firm (suppliers, clients, competitors etc.). Technology push variables refer to a pressure of new technologies to the production function of a firm, which is motivated to introduce new product range, approach new markets, increase the quality of goods, production capacity, lower the costs, environmental impact, material and energy requirements. See the CIS questionnaire for full definitions (CZSO 2001).
We performed control estimation without individual effects with jackknife robust standard error. Statistically significant were only firms with 100–999 employees (3rd equation). The computation requirements for 3SLS jackknife procedure with fixed effects were too high, but we suspect similar results showing so called “inverse-U” relationship between innovation output and firm size.
