In the paper the author considered estimation of efficiency, which measures the ability of the company to obtain the maximum output from given inputs. The analysis has been carried out by using deterministic method (on the example of the DEA method, Data Envelopment Analysis). The two-step procedure was proposed, namely the returns to scale were specified in the sample and, basing on that, the efficiency of individual enterprises was assessed. In the paper the data from the companies of a key food processing sector in Poland, namely the meat processing, was used. The analysis covered the period 2006–2011, the sample covered from 195 up to 210 enterprises (depending on the analyzed year).

It is clear that there are some theoretical foundations and emerging evidence of a positive relationship between supply chain integration and performance of a company. Nevertheless, D.C.K. Ho, K.F. Au, E. Newton postulated in this context to establish the structures and methods that help to describe and explain the relationship between integration and perfor¬mance practices of companies in the supply chain [Ho et al. 2002, s. 4415]. The paper can be treated as a next step made within the framework of the literature discussion on the method¬ological explanation of the relationship between the integration and performance.

Purpose: To incorporate a new value theory based on co-productivity into the value chain analysis. Methodology: We develop a theoretical model of co-productivity and analyze selected examples of high co-productive value chains. Our theory modifies value theories based on the classical approach (A. Smith, D. Ricardo, K. Marx), production factors of land, capital, labor, and knowledge (J.B. Clark), subjective value for the consumer (C. Menger, W.S. Jevons, and L. Walras), exchange value (A. Marshall), energy value (I. Prigogine), value added for the customer (M. Porter and P. Drucker), information value (V. Rometty), and customer attention (M. Goldhaber). Findings: We demonstrate that the co-productivity theory deeply connects all hermeneutic sources of value creation, but more importantly, it opens opportunities for adopting future-oriented sources. Originality: We present an original theory based on co-productivity, previously unused in logistics. We show how the theory helps to shape more effective value chains.
