Fewer degrees of separation make companies more innovative, creative

20.08.2007
“I read somewhere that everybody on this planet is separated by only six other people. Six degrees of separation between us and everyone else on this planet,” quips the character, Tess, in John Guare's 1990 play “Six Degrees of Separation.”

Researchers at the University of Washington and New York University who examined networks of companies in relation to their creative strengths have discovered that it is, indeed, a small world.

Corey Phelps, an assistant professor of management and organization at the UW Business School and co-author of the study, says that when companies are indirectly linked in a network of strategic alliance relationships with only a few degrees of separation, they are more innovative.

Phelps and Melissa Schilling, an associate professor at NYU, analyzed the innovative performance of 1,106 companies in 11 different industries over a six-year period. They examined the pattern or structure of strategic alliance relationships among companies in each industry. They found that how firms are connected to one another influences the number of patented inventions they obtained. Those that secured more patents were classified by Phelps and Schilling as being more creative.

“Most social networks, whether we're talking about friendships among individuals or alliances between companies, are typically clustered,” Phelps says. “Generally speaking, we only know a very small number of people and these individuals mostly know each other. As we know from high school, the world is cliquish. This is the essence of clustering.

“Because of this clustering, we might expect that it would take many connections to link two people or two firms from different parts of the world. However, if only a small number of individuals have ties that bridge clusters, then the average degree of separation between any two individuals in the network decreases dramatically. This is the essence of a small world. We know a small subset of people well, who also know each other, but thanks to a few boundary spanners, it only takes a few links to connect anyone in the world.”

According to the researchers, companies reap greater benefits when they are part of a network that exhibits a high degree of clustering and only a few degrees of separation, both of which are characteristic of a small world network.

They found that clustering enables information to travel quickly and accurately because it creates redundant paths between companies and increases the level of cooperation among them. Clusters within networks are important structures for making information exchange meaningful and useful, they add. Clustering can make firms more willing and able to exchange information. A network in which companies are directly or indirectly connected to many others by only a few degrees of separation has high reach. Reach increases the amount and diversity of information available by increasing the number of companies that provide information and by decreasing the length of the path the information has to travel. Based upon their analysis, the authors conclude that companies involved in large-scale alliance networks that exhibit high levels of clustering and reach are more innovative.

"When a small-world network structure emerges within an industry, all companies in the network benefit in terms of increased innovation, Phelps says. “Our results are particularly important because in today's knowledge economy, innovation is king. Without the ability to continually create and commercialize new products and services, companies often wither and die. This study helps us understand how large-scale alliance networks influence innovation. It improves our understanding of why some industries and regions are more innovative than others.”

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Studying fundamental particles in materials

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
