6. Limitations of the Analysis • What does it mean to say that technology affects spatial structure? • Economics & economic geography • Theoretical exploration; no data available • Only technologies, not other forces shaping spatial structure • Use of mfg technologies, not their production • Use by manufacturers, not other businesses or households • Effects on locations of households & non-mfg firms • Mfg technologies important but not dominant in shaping land use patterns A World-Class Education, A World-Class City

7. Conceptual Framework A World-Class Education, A World-Class City

8. Agglomeration Economies • Cost or productivity advantages from geographic proximity • Lead to geographic clustering, metropolitan areas, higher wages • Sources: • Common skill needs • Proximity to suppliers, transportation, R&D, etc. • Face-to-face communication • Entrepreneurship A World-Class Education, A World-Class City

9. Amenity Values • Households (esp. rich) willing to pay more to move away from unpleasant land uses • Demand for zoning to separate uses • Gentrification & displacement A World-Class Education, A World-Class City

10. Transportation Costs • Lower transportation costs encourage firms to spread out geographically • New technologies can create new modes of transportation with higher or lower costs (e.g., trucking) • Lighter-weight products reduce per-unit shipping costs Source: www.londonshippingcontainers.co.uk Date accessed: 2/6/2014 A World-Class Education, A World-Class City

11. Plant-Level Scale Economies • Large-scale production is cheaper when fixed costs are high (e.g., assembly lines) • Large factories, often on large parcels of land, favors mfg location in nonmetropolitan areas, small metropolitan areas, outlying portions of metropolitan areas • Reduction of scale economies creates opportunities for smaller manufacturers, more likely to locate on small parcels of land in denser portions of large metropolitan areas A World-Class Education, A World-Class City

12. Input Requirements • Labor-, capital-, and land-intensity of production • Labor-intensive production means many jobs in each factory • Automation issues • Disappearing jobs? • Rising wages? Source: www.i.telegraph.co.uk Date accessed: 2/6/2014 A World-Class Education, A World-Class City

15. Modular Pharmaceutical Manufacturing: Potential Impacts • Modest reduction in internal scale economies but not much impact on firms size or land use • More intense competition for pharma mfg among regions with pharma R&D A World-Class Education, A World-Class City

16. Cloud Computing • Software on remote servers • “Big data” • Already in use; large impact on production by 2025 Source: www.webmedia.greenqloud.com Date accessed: 1/28/2014 A World-Class Education, A World-Class City

17. Cloud Computing: Potential Impacts • Some reduction of internal scale economies • Opportunities for smaller manufacturers, more likely to locate on smaller parcels in denser portions of metropolitan areas • Disagglomerative potential • No need for manufacturers to co-locate with IT specialists • Virtual collaboration as substitute or complement for in-person collaboration? A World-Class Education, A World-Class City

18. Industrial Robotics • More mobile, flexible • Robots work alongside humans, learn from them • Limits on speed & precision limit them to simple, repetitive tasks • Cost is declining rapidly • Large near-term impact on production Source: www.iec.ch Date accessed: 1/28/2014 A World-Class Education, A World-Class City

19. Industrial Robotics: Potential Impacts • Reduction of internal scale economies as costs fall • Opportunities for smaller manufacturers, more likely to locate on smaller parcels in denser portions of metropolitan areas • Reduction of labor-intensity, overall mfg employment effect uncertain • Demand for engineers & technicians—could be a location factor for user firms, possibly favoring Midwest mfg centers A World-Class Education, A World-Class City

20. Advanced Materials • Novel internal structures yield superior properties • Lightweight materials • Self-repairing materials • Nanomaterials • Some already in use, others many years away Source: www.panalytical.com Date accessed: 1/28/2014 A World-Class Education, A World-Class City

21. Advanced Materials: Potential Impacts • Lightweight materials reduce transportation costs—less agglomeration of manufacturers • Possible negative health impacts lead households to locate away from mfg, reinforce separate-use zoning, possibly raise mfg wages A World-Class Education, A World-Class City

22. Advanced Sensing • Sensors on pallets & parts • Track every stage of production • Generalization of GPS & RFID • Cost is declining rapidly • Already in use; large near-term impact on production Source: www.designworldonline.com Date accessed: 2/11/2014 A World-Class Education, A World-Class City

23. Advanced Sensing: Potential Impacts • Short-term adoption by large firms but long-term reduction of plant-level scale economies • Opportunities for smaller manufacturers, more likely to locate on smaller parcels in denser portions of metropolitan areas • Demand for logistics specialists & technicians—could be a location factor for user firms • Removes inefficiencies in production process, puts premium on good freight transportation—could be a location factor for user firms A World-Class Education, A World-Class City

24. Digital Manufacturing Source: www.siemens.com Date accessed: 1/28/2014 A World-Class Education, A World-Class City • Use of IT to cut costs, increase throughput, integrate or remove steps in mfg process • Design, prototyping, testing • Connect suppliers to customer firms • Some parts already in use, others many years away

25. Digital Manufacturing: Potential Impacts • Short-term adoption by large firms but long-term reduction of plant-level scale economies • Opportunities for smaller manufacturers, more likely to locate on smaller parcels in denser portions of metropolitan areas • Dispersion of mfg suppliers and/or new agglomeration? • Customization may encourage mfg to locate near household & business consumers (metropolitan areas) A World-Class Education, A World-Class City

26. Demand for skilled production technicians—could be a location factor for user firms, favoring metropolitan areas with both IT and production workers • Removes inefficiencies in production process, puts premium on good freight transportation—could be a location factor for user firms A World-Class Education, A World-Class City

27. Additive Manufacturing (3-D Printing) Source: www.assets.inhabitat.com Date accessed: 1/28/2014 A World-Class Education, A World-Class City • Products built up from layers of material • Digital file, computer scanning, physical layering • No scrap material • Limited number of materials, no joining • Used in rapid prototyping • Probably small near-term impact on production, but expert views differ

28. Additive Manufacturing: Potential Impacts • Large reduction of internal scale economies as costs fall • Opportunities for smaller manufacturers, more likely to locate on smaller parcels in denser portions of metropolitan areas • Quieter, cleaner factories less undesirable as neighbors: less separation of land uses, possible gentrification of formerly industrial areas A World-Class Education, A World-Class City

29. Reduction of labor-intensity, overall mfg employment effect uncertain • Reduced demand for machinists & welders, clusters of these workers less of a location factor for mfg • Demand for industrial designers—could be a location factor for user firms • Reduced input use makes input transportation less important, encouraging disagglomeration of mfg A World-Class Education, A World-Class City

30. Conclusion A World-Class Education, A World-Class City

31. Summary of Impacts • General reduction of scale economies favors smaller mfg firms, less land consumption, dense metropolitan locations for mfg • Most technologies don’t make factories pleasanter neighbors, don’t encourage industrial-residential mixed land use • Demand for new skilled production workers—could be location factor for user firms • Good freight transportation more important as mfg location factor A World-Class Education, A World-Class City

32. Public Policy: Build the High Road • R&D centers • Technical assistance • Mfg-specific zoning • Workforce development • Improved freight transportation A World-Class Education, A World-Class City

33. Public Policy: Block the Low Road • Assist only firms with potential for high wages, productivity, productivity growth • Encourage (or at least don’t discourage) unionization, avoid right-to-work laws • Compete for mfg on basis of innovation, skilled labor, good freight transportation, not low wages or relocation subsidies A World-Class Education, A World-Class City
