Certified organic enterprise bases in Shandong expanded fast, then clustered around a smaller core
Certified organic agriculture in Shandong Province grew quickly between 2014 and 2023, but the expansion did not spread evenly across the province. The study tracked certified organic enterprise production bases across 16 prefecture-level cities and found that the count of bases rose substantially while spatial concentration intensified over time. A broad provincial increase masked a more uneven geography beneath the surface.
The pattern resolved into a clear core–periphery structure centered on the Jiaodong Peninsula. In practical terms, the organic sector did not diffuse uniformly through the province as it expanded; it accumulated where infrastructure, market access, and institutional support were already stronger. For enterprise-led agriculture, location is not a neutral backdrop. Certification costs, logistics, product branding, and access to buyers all shape where firms are willing to invest, and those forces can quickly magnify regional differences.
Why enterprise-led organic growth follows a selective spatial path
The paper treats enterprise-led organic agriculture as a distinct development model. Organic conversion carries a long certification cycle, high upfront spending, stringent production standards, and substantial market uncertainty. Smallholders often cannot absorb those risks alone, so enterprises become the main actors able to finance production bases, organize certification, and connect output to larger markets.
This creates an “organization-first, land-later” pathway. A firm establishes the business structure, secures certification, and then anchors production on selected land parcels in cities where industrial conditions, policy support, and market access are favorable. The result is not simply more organic land; it is a spatially selective network of certified production bases. That distinction matters because bases are the organizational units that determine whether organic agriculture becomes a durable market sector rather than a scattered set of isolated farms.
Transportation, e-commerce, and geographic indications moved in the same direction
The regression analysis linked expansion of certified bases with several structural advantages. Transportation infrastructure showed a positive association, which is consistent with the logistics demands of organic supply chains. Organic products typically require tighter coordination between production, processing, certification, and delivery, so cities with better road and transport links can lower transaction costs and reduce spoilage or distribution delays.
E-commerce connectivity also showed a positive association with base expansion. That finding fits the modern organic market: producers need direct access to consumers who are willing to pay for traceability, quality signaling, and certification labels. Digital commerce can shorten the distance between producer and buyer, especially for premium agricultural products that rely on branding and trust rather than commodity pricing alone.
GI-protected agricultural products were also positively associated with organic base growth. Geographic indication status strengthens regional identity and can enhance product reputation, making it easier for enterprises to package organic goods as place-based premium products. In a market where certification alone may not secure a price advantage, GI protection can add another layer of differentiation.
Fiscal spending ran in the opposite direction
Fiscal expenditure showed a negative association with certified base expansion. The finding does not suggest that public spending suppresses organic growth in a direct mechanical sense. A more plausible reading is that fiscal resources may be deployed to compensate for weaker areas, which means higher spending can coincide with places that still lag in enterprise-led organic development.
In other words, public finance may be following need rather than reinforcing concentration. That pattern is familiar in regional development research: stronger cities attract firms through market forces, while weaker cities receive compensatory support without immediately generating the same level of private-sector response. The result is a persistent gap between places that are structurally attractive to organic enterprises and places that depend more heavily on policy intervention.
Local clustering reveals how the sector hardened into a core–periphery system
Spatial statistics using Global and Local Moran’s I showed that the geographic organization of certified bases became more clustered over time. Local Moran’s I identified high–high concentration patterns, indicating that cities with many bases tended to sit near other cities with similarly strong organic activity. This is a classic agglomeration dynamic: once a core forms, it tends to attract more capital, knowledge, certification capacity, and supply-chain services.
The study’s interpretation is that enterprise-led organic agriculture evolves through a layered Pressure–Transformation–Support–Market mechanism. Environmental and regulatory pressure encourages the shift away from conventional production. Transformation occurs as enterprises reorient production toward certified organic standards. Support arrives through infrastructure, policy, and institutional backing. Market access then reinforces the system by rewarding firms that can move premium goods efficiently and credibly.
That sequence helps explain why spatial inequality deepens even as the sector grows. Cities with better transport links, stronger digital commerce, and established agricultural branding are able to convert policy signals into commercial expansion more effectively than peripheral areas.
What this means for regional agricultural policy in Shandong
The evidence points to a dual challenge: expand organic agriculture while preventing the sector from becoming locked into a narrow geographic core. If organic development depends mainly on market access and existing industrial advantages, peripheral cities may remain structurally disadvantaged despite overall provincial growth. Policy design therefore needs to do more than encourage certification in aggregate. It has to address the specific barriers that prevent weaker regions from attracting enterprise investment in the first place.
Shandong’s experience is especially relevant because the province is both a major agricultural producer and a national demonstration region for agricultural transformation. The rapid rise in certified bases signals real momentum. Yet the provincial map shows that momentum is unevenly distributed, and the concentration pattern itself may shape future competitiveness, resilience, and equity in the organic sector.
The study remains limited to certified enterprise production bases rather than organic farmland area or production volume, so it captures organizational presence rather than total output. Even so, that focus is valuable because certification-based bases are the sites where enterprise strategy, market access, and spatial selection intersect most clearly. The unresolved question is how policy can broaden that geography without weakening the commercial incentives that made the sector grow in the first place.
