Fig. 2 Low carbon index and average of each farm household
As shown in Fig 3a, by comparing the scores of the six primary
indicators of each farmer, it can be found that the area formed by the
area connected by the dots of each indicator score is significantly
higher in M1 than in M2 and M3, and the area size is M2 >
M1 > M3, mainly because M2 has a greater advantage in
”envelope structure” and ”energy use”. M2 > M1
> M3, mainly because M2 has greater advantages in
”envelope” and ”energy use”. As can be seen from Fig 3b, the area of H2
formed by the connection of the dots of each index score is
significantly higher than that of H1 and H3, and the size of the area is
H2 > H3 > H1, although the advantage of H2 in
”economic factors” and ”behavioral habits” is not obvious. However, H2
has an outstanding performance in ”energy use”, and according to the
previous section, ”energy use” has a higher weighting factor.
