The Impact of Resource-Based City Sustainable Development Policies on Industrial Structure Upgrading: An Analysis of FDI, Green Technology Innovation, and Human Capital Mechanisms Based on Chinese Cases

Research on Policy Drivers for the Transformation and Upgrading of Resource-Based Cities

As centers for economy, education, and science, the sustainable development of cities is crucial for economic growth. Resource-Based Cities (RBCs), due to their abundant natural resources (such as coal, oil, and metals), have historically laid the foundation for China's industrialization. However, their over-reliance on local resources, single industrial structures, and the risk of resource depletion present severe transformation challenges. To address this challenge, China issued the "Sustainable Development Plan for Resource-Based Cities" (SDPRC) in 2013.

The SDPRC is not just a policy framework but a systematic project aimed at promoting the upgrading of the industrial structure of resource-based cities. This study treats the SDPRC as a quasi-natural experiment to examine its actual impact on the industrial structure upgrading of resource-based cities.

Logic of Capital Inflow and Industrial Upgrading

The core logic of capital entering resource-based cities lies in the contradiction between resource endowments and industrial structure. Under the traditional model, the urban industrial structure is highly concentrated on local resource extraction and primary processing, which limits economic diversification and long-term sustainability. The introduction of the SDPRC aims to break this single structure and guide cities toward industries with greater resilience and innovation capabilities. The inflow of capital and industrial upgrading are essentially manifestations of the process by which resource-based cities transition from being "resource-dependent" to "innovation-driven" under policy guidance.

Analysis of Driving Mechanisms of Capital Flow

Research results indicate that the promoting effect of the SDPRC on the industrial structure upgrading of resource-based cities is not a single direct effect but is driven by multiple internal mechanisms:

1. Green Technology Innovation Effect: The policy encourages cities to transform towards low-carbon, high-value-added industries, which directly promotes green technological innovation, providing technical support for the upgrading of the urban industrial structure. 2. Human Capital Effect: The policy guides cities to focus on the cultivation and optimization of human capital, enhancing the intrinsic driving force for the upgrading of urban industries. 3. FDI Effect: The optimization of the policy environment and the adjustment of the industrial structure attract more foreign direct investment (FDI) into resource-based cities, providing key external capital and technological input for industrial upgrading.

Heterogeneity Analysis: Impact of Regional Differences

Heterogeneity analysis further reveals regional differences in policy effectiveness. The study found that the promoting effect of the SDPRC on industrial structure upgrading is more significant in resource-based cities located in the southeast of the "China Red Line." Furthermore, the policy's driving effect on industrial structure upgrading is more pronounced in regions with higher GDP per capita. This indicates that the effectiveness of the policy interacts with the economic foundation and geographical location of the target city.

Capital Signals and Long-Term Trends### Capital Signals and Long-Term Trends

From the perspective of the capital market, policy-driven structural reforms indicate that capital is re-evaluating the investment value of Africa and other emerging markets. Capital is no longer just focused on the simple extraction of resources but is more favoring industrial upgrading paths that are policy-driven, innovative, and sustainable. Resource-based cities that can successfully activate mechanisms for green technology innovation and human capital accumulation will become the focus for capital seeking long-term value. This event signifies that global capital is shifting from a purely "resource acquisition" mindset to an assessment framework of "sustainable development models."

Does this event mean that global capital is re-evaluating the investment value of Africa? Yes, it indicates that capital is shifting from a simple dependence on traditional resource endowments to an assessment of the innovation capabilities and sustainable development potential embodied by policy-driven industrial structural upgrades. It suggests that the future capital flow landscape in Africa over the next decade will place greater focus on emerging markets capable of achieving green transformation and technological innovation.
