7 Powers im Glas- und Keramiksektor Bremen (WZ C23): Wettbewerbsvorteile für den Mittelstand
Intro: Bremen as a location for C23. Historically, Bremen had brickworks (Backsteine), but today it’s more about specialized glass (e.g., aerospace, optics, or construction glass) and ceramics (technical ceramics). Wait, what are real companies in Bremen for C23?
- Glass: SCHOTT AG has a site in Bremen? Actually, SCHOTT is in Mainz. But there are companies like “Bremer Werk für Glasbau” or specialized glass processing. Let’s check real data: Bremen has “Glaswerkzeug”, “Glas Baustoffe”. There is “Bremen Bonds” (no, that’s finance). Let’s look at the Bremen economic structure. C23 includes manufacture of glass and glass products, ceramic products, and building materials (stones, sand, clay). Bremen has a strong construction sector, so building materials (e.g., concrete, but concrete is C24? No, C23 is “Herstellung von Glas und Glaswaren, Keramik, Verarbeitung von Steinen und Erden”). In Bremen, there are companies like “Kieswerk”, “Ziegelwerk”. Also, “Otto Fuchs” is metals. What about “Dörentrup Quarzglas”? No, that’s Lippe. Let’s focus on the broader C23 in Bremen: e.g., “Glasbau Bremen”, “Bremer Baustoffe”, “Nordziegel”, or just talk about the structural challenges of C23 in a city-state like Bremen where heavy industry is limited but specialized manufacturing (e.g., technical glass for aerospace, or high-end ceramics) exists. Bremen is a hub for aerospace (Airbus), so technical glass/ceramics for aerospace (e.g., insulation, composites) is a realistic angle. Also, the port logistics for building materials (cement, stones) is huge in Bremen. Let’s mention “Bremer Baustoffzentrum”, “Weser-Kies”, “Hanson Deutschland” (HeidelbergCement) in Bremen. Also, “Glaserei” and “Glasbau” for the construction sector.
Apply 7 Powers (Hamilton Helmer):
- Scale Economies (Skaleneffekte)
- Network Economies (Netzwerkeffekte)
- Counter-Positioning (Kontra-Positionierung)
- Switching Costs (Wechselkosten)
- Branding (Markenbildung)
- Cornered Resource (Monopolisierte Ressource)
- Process Power (Prozessmacht)
Structure:
Die Branche Glas, Keramik und Steine (WZ C23) in Bremen: Ausgangslage
Bremen as a city-state. Limited space for heavy raw material extraction, but strong in processing, logistics, and high-tech applications (aerospace, maritime). Mention specific location factors: Hafen (logistics for raw materials like sand, cement, stones), Nähe zu Airbus / OHB (demand for technical ceramics/glass), Hochschule Bremen (materials science).
Methodische Grundlage: Die 7 Powers (Link to /frameworks/)
Brief explanation of the framework.
Die 7 Powers im Kontext von Bremen (WZ C23)
1. Scale Economies: Logistik und Bündelung am Bremer Hafen
Cement, gravel, sand. Companies like CEMEX or HeidelbergCement use the port. Scale in bulk handling.
2. Cornered Resource: Fachkräfte und Hochschul-Kooperationen
University of Bremen (MAPEX Center for Materials and Processes), HS Bremen. Access to specialized material scientists.
3. Switching Costs: Technische Keramik für die Luft- und Raumfahrt
Suppliers to Airbus/OHB have high switching costs due to certification (EN 9100).
4. Branding: “Bremer Backstein” und Architektur-Glas
Heritage of brick architecture. High-quality glass for facades.
5. Process Power: Präzisionsglasbau und CNC-Bearbeitung
Small and medium enterprises (KMU) with proprietary machining processes.
6. Counter-Positioning: Dezentrale, flexible Produktion vs. NRW-Massenfertigung
Bremen KMUs counter-position against the large Rhineland (NRW) or Bavaria (Bayern) mass producers by being agile and close to the customer.
7. Network Economies: Cluster Maritime und Aerospace
The Bremen aerospace and maritime cluster creates network effects for specialized glass/ceramic suppliers.
Standortfaktoren Bremen im Vergleich (vs. NRW, Bayern, Thüringen)
- NRW: Heavy concentration of glass (e.g., Flachglas in Weißwasser? No, that’s Saxony. NRW has Saint-Gobain, Pilkington in Gelsenkirchen). Mass production, but high energy costs and space constraints.
- Bayern: Strong in technical ceramics (e.g., Rosenthal, CeramTec in Stuttgart region, but Bavaria has strong automotive ceramics).
- Thüringen/Sachsen: Glass industry (Jena, Weißwasser).
- Bremen: Logistics hub, aerospace pull, but high real estate prices and limited expansion space.
