香港電力彈性需求問題

Hong Kong's electric market is not a 100% elastic demand.

Actually your question is about what is the determiner of the price elasticity of demand?

The following factors determine price elastic demand:

1. Availability of close substitutes ( No substitutes )

2. Necessities or luxuries ( necessities )

3. Definition of the market ( good )

4. share of expenditure on the good ( have no data supports if it's high, it can be elastic, otherwise can be inelastic)

5. Habit forming ( no comment )

6. Product durability ( must maintain )

7. The length of time involved ( have no data supports if it's long, elastic, short inelastic)

彈性需求的意思係指該物品/服務有多少替代品,替代品越多,彈性越大
,香港的電力市場由兩大公司壟斷(港燈:港島區/中電:新界九龍區)
兩地市民不能替換電力供應商,所以
香港電力市場的彈性需求係0!
