Tutor lesson-prep guides · Junior Secondary Geography

Students know Hong Kong used to make things, but cannot say by how much the scale changed. This lesson uses four sets of figures: jobs down from 900,000 to 80,000, factories from 50,000 to 9,000, manufacturing at about 1% of GDP, and fewer than nine workers per factory.

Objectives — Students can: (1) use employment and factory numbers to calculate the scale of decline and give three causes; (2) explain the factory-front shop-back division of labour and its benefits and costs to Hong Kong; (3) name two directions of re-industrialisation and use the average workers per factory to contrast modern plants with old ones.

01 Prerequisites (3-minute check)

If any of these fails, fix it before the lesson starts.

Skill	Quick check	Pass mark
Industry types	A garment factory or a bank: which is manufacturing?	The garment factory, because it turns materials into products
Percentages	Employment falls from 900,000 to 80,000. What share remains?	About 8.9%
GDP	What does GDP add up?	The total value of goods and services produced in a place in a year

02 Lesson flow (45 minutes)

Time	Stage	Tutor does	Student does
0-5 min	Two eras side by side	Write 900,000 and 80,000 jobs and ask for the ratio	About one eleventh remains
5-15 min	Size of the decline	Model 80,000 / 900,000 and 9,000 / 50,000	Get 8.9% and 18%
15-27 min	Why relocate	Move from land price, wages and environmental cost to plants and container ports in the Pearl River Delta	Give three push and one pull factor
27-37 min	Factory-front shop-back	Hong Kong takes orders, designs and finances; the delta produces	Say which side does which stage
37-42 min	Re-industrialisation	Use the 8.9 workers per factory to explain small but advanced, plus biotech	Say modern plants rely on technology, not headcount
42-45 min	Exit check	Ask what share of GDP manufacturing is, and whether industry has vanished	About 1%, but high-value stages remain

03 Teaching script (read it out)

Scene 1: Scale of decline: two divisions cover forty years

Skip the storytelling and go to two divisions. First, manufacturing employment fell from about 900,000 in the 1980s to about 80,000 today, so 8 divided by 90 is 8.9%, less than a tenth. Second, factory numbers fell from about 50,000 to about 9,000, leaving 18% and a fall of 82%. Read the two together and an important detail appears: the fall in factories at 82% is smaller than the fall in jobs at 91%, which means the surviving plants are smaller, and 80,000 workers across 9,000 factories is about 8.9 workers each. Push students to draw the conclusion: Hong Kong did not lose industry, it moved to small-scale high-technology production, which is exactly the premise of re-industrialisation.

Ask students what it means that the factory decline is smaller than the employment decline

Scene 2: Why relocate: separate push from pull

Students write that labour was cheaper on the mainland and stop, which earns half the marks. Teach them to split causes into push, which drove factories out of Hong Kong, and pull, which drew them to the delta. Push: high land prices and rents, labour shortage and rising wages, tighter environmental rules, urban land needed for housing and commerce. Pull: cheap plants and land, ample labour, tax incentives, proximity to Hong Kong for orders and exports. Only then give the timeline: production lines moved from the 1980s, at scale in the 1990s, and after 2000 even procurement and some design followed. That structure is what turns one sentence into a full answer.

Ask students for two push and two pull factors and the decade relocation began

Scene 3: Factory-front shop-back and re-industrialisation: two sides of one shift

Make the division of labour explicit: Hong Kong takes orders, designs, controls quality, arranges finance and shipping, while the delta supplies plants, production and packing. The benefit is that Hong Kong keeps the high-value stages and the related jobs; the cost is the loss of local manufacturing posts, a gap in skilled trades and heavy dependence on services, which now provide about 93% of GDP. Re-industrialisation answers that cost in two directions: advanced manufacturing such as automation and precision engineering, and biotech and medical-related production. Close with the 8.9 workers per factory figure: new plants compete on equipment and know-how, so a few dozen workers can match the output of an old plant with hundreds.

Ask students what the front shop and the back factory each do, and the two directions of re-industrialisation

04 Question types and worked steps

Type	Example	Steps	Answer
Decline calculation	Manufacturing employment falls from 900,000 to 80,000. What share remains, and what is the fall?	(1) 8 / 90 (2) multiply by 100 for 8.9% (3) subtract from 100 for the decline	8.9% remains, a fall of 91.1%
Average scale	There are 9,000 factories and 80,000 workers. What is the average number of workers per factory?	(1) 80,000 / 9,000 (2) the unit is workers (3) answer about 8.9	About 8.9 workers, small-scale high-technology plants
Factor classification	Sort two push and two pull factors for relocating production lines north.	(1) Push means pressure in Hong Kong (2) pull means attraction in the delta (3) be specific about land, wages and rents	Push: land prices and labour shortage; pull: cheap plants and ample labour
Discussion	Manufacturing is about 1% of GDP. Does Hong Kong therefore not need industry?	(1) State the small share (2) note the high-value stages still here (3) give re-industrialisation directions (4) give a position	No: the output share is small but design, finance and quality control matter, and re-industrialisation targets advanced manufacturing and biotech

Sanity check (teach this): Run three percentage checks: (1) the numerator is the current figure and the denominator the earlier one, since reversing them gives 1,125%; (2) the decline is 100 minus the remaining share, and the two must add to 100; (3) the average scale must be plausible, because 8.9 workers per factory makes sense while 0.11 does not, and a result like that means the fraction was inverted.

05 Independent practice (3 questions)

Question	Answer	What to watch
Employment falls from 900,000 to 80,000: what share remains?	About 8.9%	Did they reverse the two figures?
9,000 factories and 80,000 workers: average per factory?	About 8.9 workers	Did they use 9,000 as the numerator?
What share of GDP is manufacturing?	About 1%, against about 93% for services	Did they confuse employment share with output share?

06 Common mistakes and what to say

Mistake	Student writes	Say this
Only one cause	Factories moved out because mainland labour was cheap.	“Cheap labour is only one pull factor. Split it: two factors pushing factories out of Hong Kong and two pulling them to the delta.”
Employment share treated as output	Manufacturing employs 80,000, so it is 8% of GDP.	“80,000 is a headcount, not output. Manufacturing is about 1% of GDP, and the two numbers answer different questions.”
Reversing the two figures	900,000 divided by 80,000 is 11.25, so manufacturing grew.	“The question asks what share remains, so the numerator is today 80,000. Do 8 divided by 90 and multiply by 100.”
Assuming industry vanished	Hong Kong has no industry left, it is all services.	“There are still 9,000 factories and 80,000 jobs, just at a smaller scale. Re-industrialisation builds on that base.”

07 Homework (paper, section and question numbers)

Population structure chapter, question 2 (labour force) — Lost manufacturing jobs shape the labour force directly
Transport network chapter, question 2 (freight and roads) — After relocation, local delivery became cross-border freight
Agriculture and fisheries chapter, question 3 (comparing methods) — Farming decline and industrial relocation share the same cost-push logic

08 Exit check (last 5 minutes)

Question	Answer	Decision
Manufacturing employment falls from 900,000 to 80,000. What share remains?	About 8.9%, a fall of 91.1%	Answering 11 times means the figures were reversed
Describe the factory-front shop-back division.	Hong Kong takes orders, designs and finances; the delta produces	Vague talk of shops and factories is not specific enough
What are the two directions of re-industrialisation?	Advanced manufacturing and biotech-related production	Answering “build more factories” means high value was missed

09 Tutor FAQ

Must students memorise 900,000 and 80,000?

The magnitudes are enough: jobs went from the hundreds of thousands to the tens of thousands, less than a tenth remaining. The conclusion is small-scale high-technology production.

Why did factories fall less than jobs?

The surviving plants are smaller and more automated, so they keep running with fewer people, which is why the average is about 8.9 workers.

Does re-industrialisation mean bringing old factories back?

No. Land and wage conditions have changed, so it relies on automation, precision engineering and research, producing high value with few workers rather than returning to labour-intensive production.
