## Lesson: Building the Technology Matrix from the Input-Output Table
### Example 1: Input-Output Table
To convert the provided input-output data into a technology matrix, please examine the table below:
| | To A | To B | To C |
|----|------|------|------|
| **From A** | 0 | 200 | 450 |
| **From B** | 400 | 300 | 300 |
| **From C** | 0 | 0 | 600 |
**Total Output:**
- From Industry A: 1,000
- From Industry B: 2,000
- From Industry C: 3,000
Below the table is an interactive section that provides support features for further assistance:
- **Read It:** Links to a detailed explanation of the concept.
- **Watch It:** Links to video tutorials for visual learners.
- **Talk to a Tutor:** Offers personalized help through tutoring services.
### Steps to Obtain the Technology Matrix
1. **Identify the Input and Output Data:**
- Use the given table that shows the flow of goods and services between industries A, B, and C.
2. **Calculate the Technology Coefficients:**
- For each cell in the matrix, divide the input value by the total output of the 'from' industry.
- Example: For Industry A supplying B, the technology coefficient is 200/1000 = 0.2.
3. **Construct the Technology Matrix:**
- Assemble the calculated coefficients into a matrix format.
### Example Technology Matrix
Using the above input-output data, the technology matrix (often referred to as the 'A-matrix') can be assembled:
\[
\begin{bmatrix}
\frac{0}{1000} & \frac{200}{1000} & \frac{450}{1000} \\
\frac{400}{2000} & \frac{300}{2000} & \frac{300}{2000} \\
\frac{0}{3000} & \frac{0}{3000} & \frac{600}{3000}
\end{bmatrix} =
\begin{bmatrix}
0 & 0.2 & 0.45 \\
0.2 & 0.15 & 0.15 \\
0 & 0
