I&D para a COMPETITIVIDADE - parte VIII: o caso alemão


Standing out: In the Global Competitiveness Index, Germany scores higher than the U.S. on several measures, including the quality of its institutions and infrastruc­ture. See details on the scoring in the report listed in More to Explore.


In Brief
·         Germany owes its robust economy of recent years in part to the success of its manufacturing sec­tor, from basic materials to tools on the factory floor.
·         The reason Germany has remained competitive against cheaper manufacturers in Asia and else­where is that it has made good use of new technology.
·         The Germans have excelled in old industries such as automobiles and are building centers of excel­lence in biotechnology and other emerging areas.

Felix Michl and Philipp Stahl huddle over a gleaming new three-armed robot in the sprawling laboratory at the Technical University of Munich (TUM). The robot picks up tiny patches of carbon fiber, each less than a tenth of a millimeter thick but con­taining 24,000 filaments, and quickly assembles them into a triangular shape. The trickiest task, the investigators say, is to write the software that translates a 3-D com­puter model of any part—in this case a bicycle seat, but it could also be a medical prosthesis or an automobile component—into instructions for the robot's intricate movements, including the exact position at which the fibers will have their maximum strength and durability. When the project is completed, Michl will use it in his Ph.D. thesis, and Stahl will finish up his undergraduate studies. But the work will get a se­cond life in German factories, including a 70,0000-square-foot, state-of-the-art BMW production facility 30 miles down the road near the medieval town of Lands­hut, where engineers are crafting the next generation of automobiles.
That may be. The steady pipeline of innovation that runs from university and gov­ernment research labs to manufacturers such as BMW is one of the secrets driving the booming German economy. Long belittled as lowly metal bending, German man­ufacturing sailed through the financial crisis with hardly a dent in profits and em­ployment, even though its workers, among the world's most highly paid, make 10 times what their Chinese counterparts earn. German exports have held their share of the global market against China and other emerging countries, even as the U.S. share has plummeted. Rising industrial employment is one reason Germany, as of May, had a jobless rate of only 5.6 percent compared with America's 8.2 percent, according to the Organization for Economic Co-operation and Development. German manufactur­ers have stayed globally competitive because their products—like the BMW i3—are chock-full of science and innovation.
One major factor for Germany's success is that it has managed to tap homegrown sci­entific research and expertise to move up the technological ladder, concentrating on innovative products and processes not easily copied or undercut by cheaper wages. The textile industry is a case in point. Like America, Germany long ago lost the bulk of its clothing and fabrics manufacturing to cheaper locales such as China, India and Turkey. Still, German companies kept a commanding share of the global market for the ever more complex machines that weave, braid and knit textiles, riding the in­vestment boom in low-wage countries. Meanwhile many of Germany's former textile makers also went high-tech, shifting their specialty to industrial textiles for the auto­motive and aerospace sectors. Today the national textile industry is at the forefront of composites research, cooperating with universities and government tech centers to develop the precision machinery that braids the carbon fibers into strands—not un­like wool or cotton, except on a microscopic scale. Had Germany given up this indus­try, it would lack the basis for producing those next-generation composites now being developed at TUM and other labs.
The key for getting this research out of the lab and into the marketplace is the close partnership between research at the universities and today's high-tech factory floors. Most German manufacturers have rich budgets for research, which they often buy from others. Unlike many American firms that might fund a professorship or make a general donation to a university department, German companies usually approach universities with very specific problems they want solved. At TUM, for example, the composites department is funded by SGL Carbon, a German maker of carbon fibers that wants to know what kinds of materials are best suited for the next generation of manufacturing processes. BMW has about a dozen of the department's Ph.D. stu­dents on its payroll; their dissertation projects are part of preproduction research for the i3. Equipment makers such as KUKA (robots) and Manz (composites presses) are deeply integrated into the university's research as well.
Multiply this intense networking by dozens of universities specializing in technology and engineering. At RWTH Aachen University, more than 20 university institutes fo­cus on state-of-the-art production techniques, cooperating with machinery makers, robot companies and software developers to make manufacturing processes so effi­cient that a high-wage country such as Germany can compete with the likes of China. RWTH Aachen is now building a $2.5-billion industrial park for companies partner­ing in this research. The Karlsruhe Institute of Technology specializes in nanotechnology and materials science, working with Germany's leading chemicals com­panies, such as BASF, to design new substances that will allow batteries to store renewable energy more efficiently and cheaply. At the Technical University of Dres­den, researchers partnering with chipmakers and infotech companies are developing integrated circuits that use one hundredth the energy of current-generation electron­ics.
The German government, too, plays a crucial role. Whereas the country funds excel­lent labs for basic science, such as the Max Planck network of 80 institutes covering disciplines as disparate as particle physics and evolutionary biology, Germany's most economically successful research institution is the Fraunhofer Society. Its network of 60 technology centers is cofinanced by the government and businesses and thus is strictly market-driven. Fraunhofer's $2.5-billion annual budget is also flush with pa­tent income, most notably from its invention of the MP3 data format in the 1980s.
A unique trust
Closely partnering with nearby universities, each Fraunhofer center acts as a trans­mission belt to an entire cluster of companies networked with the center—and with one another—through collaborative research designed to find its way into processes and products. There are centers for every conceivable industrial sector, including pol­ymer research for chemical companies, precision optics for the makers of sensors and lasers, and nanoelectronics to produce next-generation IT components.
Several centers, such as the Fraunhofer Institute for Production Technology in Aa­chen, focus on developing cost-efficient manufacturing techniques to keep Germany competitive with China. And for composites research, there is a Fraunhofer project group in Augsburg near Munich that grew out of a cold war–era rocket propulsion lab. Partnering with TUM and more than 50 companies, including BMW, Audi and Airbus owner EADS, the Augsburg center is already working toward the next genera­tion of composite fibers derived not from petroleum but from lignin, an inexhaustible by-product of the wood and paper industries.
What also speeds up the transmission of these technologies is the encouragement of job-hopping of researchers and engineers. The average Fraunhofer scientist, for ex­ample, switches to an industrial company after five to 10 years, and many of the best corporate engineers also do stints as professors or Fraunhofer directors. Klaus Drechsler, professor and head of the Institute for Carbon Composites at TUM, spent part of his career at EADS developing composites for the Airbus. Now he is in charge of setting up the new Fraunhofer center for composites in Augsburg. This kind of job-hopping, crucial in diffusing expertise and technology, is much rarer in the U.S., where a government researcher usually stays in one place for life.
This intense and complex collaboration is typical of German innovation. Much of it grew over decades among companies large and small that are now so used to working together they know instinctively what information they can share and what is best kept proprietary. “This trust between companies and institutions that cooperate but also compete is unique—you don't see that in very many countries,” says Beñat Bil­bao, an economist at the World Economic Forum in Geneva and co-author of the lat­est “Global Competitiveness Report,” which every year shows Germany outranking the U.S. in industrial innovation. Most of these clusters of companies and their sup­pliers grew organically over decades (in some cases over centuries, such as the former clockmakers in the Black Forest that are now the world's leading producers of preci­sion surgical instruments), which makes them not so easy to copy.
Still, the Germans manage to keep creating such networks in newly emerging indus­tries. One of the latest is the BioEconomy Cluster near Leipzig, where a network of more than 60 companies and research institutes is developing ways to produce chemicals and plastics from biomass, replacing costly and CO2-spewing petroleum not just for energy but for other products now refined from oil. When Fraunhofer sets up new tech centers, it identifies companies and institutions that are already strong in their fields instead of trying to create something from scratch. “Our philosophy is to take something that's already working and water it so that it grows,” says Fraunho­fer Society president Hans-Jörg Bullinger. In setting up the new carbon composites cluster, for example, Fraunhofer identified existing companies and university de­partments and provided funding, staff and a facility to encourage collaborative re­search.
The second lesson, Bullinger says, is to commit to the long haul. New Fraunhofer centers have their funding secured indefinitely and are left to themselves, with no evaluation taking place for the first five years beyond the requirement that they raise double their seed money from private companies. The companies, too, are invested for the long term; many of Germany's most innovative and tech-driven manufactur­ers are family-owned companies that do not worry about quarterly reports. A typical German tech company looks like Trumpf, an almost invisible, family-owned firm that has been a world leader in industrial laser technology for over a generation and now has annual sales of almost $3 billion. Fraunhofer, too, added 3,000 new researchers in the worst phase of the financial crisis. “Many countries have tried to copy us,” Bullinger says. “But their efforts fail because they think short term.”
That may be the fatal flaw in President Barack Obama's proposal, unveiled in March, for a $1-billion National Network for Manufacturing Innovation that is explicitly modeled after Germany's Fraunhofer. If Congress approves it, the network will be a public-private partnership in cooperation with manufacturing companies to put in place up to 15 manufacturing technology centers around the country—so far so good. But the funding is only set up for the first four years. In Bullinger's view, that is much too short for the best companies and researchers to commit to serious projects. “The likely result is a scramble for project money instead of something sustainable,” Bull­inger says. Still, he says, it is a step in the right direction.
The German system has its weak sides, of course. The country's precision culture can be better at perfecting existing technologies than inspiring radical innovation. And the nation has had its periods of “technophobia,” during which politicians and protest movements chase away promising high-tech industries, such as biotech in the 1980s. But Germany's drive for industrial innovation has put to rest the old cliché that man­ufacturing is low tech and has set an example of how to go head-to-head with China. Those graduate students reinventing manufacturing in a university lab in Munich are a model to learn from.

Falou-se aqui do Instituto Fraunhofer. Pois bem o Prof. José Encarnação é português e foi Director do Fraunhofer IGD.

Infelizmente cá em Portugal os empresários, em particular nas PME, frequentemente são pouco qualificados e não acreditam no valor da investigação. Também estão frequentemente forçados a resolver problemas de curto prazo e com um ambiente assim é difícil de fazer I&D de valor. Muitas vezes a selecção de um fornecedor não é feita por qualidade ou preço mas por relações pré-existentes entre as empresas em questão. Isto também acontece noutros países mas cá em Portugal o problema é mais gritante. Assim não há muito espaço para I&D mas ainda se vai fazendo algo ocasionalmente.

Ao contrário do que se possa pensar até existe cá em Portugal alguma indústria de máquinas-ferramenta. Também existe alguma indústria aeronáutica. Não falo das OGMA que passam grande parte do tempo a instalar upgrades ou a reparar aeronaves mas sim de empresas privadas de menor dimensão que constroem aviões de pequena dimensão para particulares.
