## Compute Capital Stock in Chinese Provinces

### Description

This function compute capital stock of provinces in China using the method by Zhang (2008).

### Usage

```CompK_ZJ(
yr = NULL,
invest = NULL,
InvestPrice = NULL,
delta = 0.096,
prv,
bt = 1952
)
```

### Arguments

 `yr` a numeric vector about years. If you only need capital stock before 2017, you can use its default `NULL`. If you need to compute capital stocks in other years (for example 2018,2019), you can set, for example, `yr = c(2018,2019)`. `invest` a numeric vector about investment, its length equal the length of `yr`, and its units is 100 million in current price. `InvestPrice` a numeric vector about price indices of investment, its length equal the length of `yr`, and it is a fixed base index with equaling 1 in `bt`. `delta` a rate of depreciation, a scalar number. `prv` a province name, a scalar character. It's Chinese phonetic alphabets. `bt` a scalar number, such as 2000. It means computing capital stock with its price equal 1 in `bt`

### Value

The function return a data.frame, and its 1st column is province, 2nd column is year, 3rd column is capital stock, 4th column is the price index of investment.

### Note

The parameter `InvestPrice` is a fixed base index with equaling 1 in 1952 by default. However, we often only get a price indices of investment with equaling 1 in last year. You can use `data(asset)` to get `InvestPrice` in any year (before 2017) with equaling 1 in 1952. So, it is easy then.
