The Pre-1979 Context: A Backward Border Region

Before the thunderous arrival of the special economic zone (SEZ) designation in 1979, the territory that would become Shenzhen was not a nascent metropolis but a quiet, struggling, and geographically marginalized backwater: Bao'an County. Understanding this foundational "before" state is not merely an act of historical curiosity; it is an analytical imperative. The magnitude of Shenzhen's subsequent metamorphosis—from a sleepy border region to a global megacity—can only be measured against the stark baseline of its pre-reform conditions. This chapter establishes that baseline, deconstructing the confluence of geographical, economic, demographic, and administrative forces that consigned Bao'an to the periphery of Guangdong's development and China's modernizing narrative. We will examine how its very location became a liability, how its agrarian structure stifled productivity, how its historical role as a migration corridor drained human capital, and how its low administrative rank ensured chronic neglect. Together, these factors created a powerful gravity of underdevelopment, making the later transformation not just impressive but seemingly antithetical to its inherent conditions.

**1.1 Geographical Marginality: The Curse of the Frontier**

Bao'an County's defining physical characteristic was its position on the southern fringe of Guangdong Province, a borderland in the most literal sense. For centuries, its identity was shaped by its adjacency to the British colony of Hong Kong, a relationship that fostered not integration but separation and tension.

The Physical and Strategic Landscape The county's geography was a study in contrasts. To the south, a serpentine boundary—largely following the Sham Chun River (Shenzhen River)—separated it from the New Territories of Hong Kong. This was not a porous, commercial frontier but a heavily fortified "closed border" (*guan'ao*). The terrain itself was a mix of alluvial plains, low hills, and coastal inlets, but its strategic value was perceived almost exclusively through a military and security lens by the central government in Beijing. Following the establishment of the People's Republic of China in 1949 and the consolidation of the Hong Kong border, this 27-kilometer frontier became one of the most militarized and regulated inland borders in the world. Barbed wire, watchtowers, and patrols defined the landscape, turning a potential zone of exchange into a zone of containment.

This border status had immediate economic consequences. While Hong Kong, even as a British colony, was being woven into global trade networks and evolving into an industrializing port, Bao'an was cut off. The flow of goods, capital, and ideas was severely restricted, permitted only through a handful of tightly controlled official crossing points like Shatoujiao. The county was, in effect, placed in a developmental straitjacket. Its southern coastline, with natural deep-water advantages, was rendered inert for large-scale commercial shipping. Its proximity to one of Asia's great financial centers became an irrelevance, even a hazard, as the border drew a line through natural economic spheres.

Peripheral Position Within Guangdong Even within the provincial context of Guangdong, Bao'an was marginal. The economic and political heart of the province gravitated toward the Pearl River Delta's core cities: Guangzhou, the provincial capital and historic commercial hub; and the industrializing cities of the eastern delta, like Shunde and Dongguan, which were more integrated into intra-provincial networks. Bao'an lay on the periphery of this delta system, its connections to the interior weak. The primary transportation artery, the Guangzhou-Kowloon Railway, ran through the county but had limited local impact; it was a through-line connecting the provincial capital to the British border, not a catalyst for county-wide industrialization. Bao'an's county seat, located in what is now the old town of Shenzhen (Nantou), was a typical regional administrative center, serving a vast but sparsely populated rural hinterland, not a hub of commercial activity.

The concept of "periphery theory" from economic geography is instructive here. A core region (like Guangzhou or Hong Kong) generates agglomeration economies, innovation, and capital accumulation. Peripheral regions, lacking these dynamics, often experience a "backwash effect" where resources—including human capital—migrate toward the core, exacerbating local underdevelopment. Bao'an was trapped in this dynamic, doubly marginalized: by the national security apparatus that sealed its southern border and by provincial economic patterns that flowed elsewhere.

A Visual Analogy: The "Bowl" Effect Consider the Pearl River Delta as a series of interconnected economic bowls. Guangzhou, Hong Kong, and later emerging industrial towns like Dongguan were bowls filling rapidly with capital, labor, and enterprise. Bao'an, however, was a bowl with a large crack in its southern side (the closed border) and a very narrow, poorly connected neck to the northern bowls. It could not retain its own resources, nor could it easily receive overflow from the delta's core. Its geography was not an asset waiting to be leveraged; it was a structural deficit.

**1.2 The Agrarian Economy: Subsistence and Stagnation**

The official economic description of Bao'an County in 1978 was "primarily agrarian, with a small fishery." This simple phrase masked a reality of low productivity, vulnerability, and minimal state investment that characterized much of rural China but was acute in this border region.

Structure of Agricultural Production Agriculture was dominated by double-cropping rice systems in the alluvial plains, supplemented by sweet potatoes, peanuts, and a variety of vegetables in the hilly areas. The "household responsibility system" had not yet been implemented; farming was organized under the people's commune system, which had been in place since the late 1950s. This system suffered from the classic "tragedy of the commons" problem: collective ownership led to weak incentives and low labor effort. Output quotas were set by the state, with a significant portion of the harvest requisitioned as taxes and for urban supply, leaving peasants with barely enough for subsistence.

A crucial metric is land productivity. In 1978, Bao'an's average grain yield per hectare was significantly below the provincial average for Guangdong's more developed delta counties. For instance, data from the *Guangdong Statistical Yearbook* (1979) suggests yields in core delta counties like Shunde or Nanhai could be 20-30% higher due to better irrigation, fertilization, and slightly more flexible local management. Bao'an's yield was further constrained by its relative lack of major irrigation infrastructure projects compared to the delta's heartland.

The "Fishery" and Coastal Economy The official characterization as having a "small fishery" is telling. It was not a modern, commercial fishing industry but a subsistence and local-market activity. The coastal villages along the South China Sea engaged in net fishing and shellfish gathering, primarily for local consumption. There was no deep-water port, no cold storage, no processing facilities to connect this resource to larger markets. The county's 100+ kilometers of coastline were an underutilized asset, rendered economically inert by the lack of infrastructure and the closed-border policy that prevented access to Hong Kong's massive fish market.

The Tax Burden and Capital Starvation The agrarian economy was further squeezed by the fiscal relationship with higher levels of government. As a county, Bao'an had limited fiscal autonomy. A large portion of its agricultural tax revenue—both in kind and in cash—was extracted by the provincial and prefectural (then Huiyang Prefecture) governments. This created a vicious cycle: low agricultural surp
