How Efficient China’s Tiered Pricing Is for Household Electricity: Evidence from Survey Data

Round 1

Reviewer 1 Report

The research subject receives attention in China and the manuscript is well-written. However, I would like to mention a few issues:

- Page 2, line 56 the sentence cannot be understood.

- Figure 2, some subjects cannot be uderstood.

- The most recent reference is dated 2020. References dated 2021 and 2022 can be added.

Reviewer 2 Report

Review of Paper “How Efficient is China’s tiered pricing for household electricity: Evidence from survey data”

 This article used data from the Chinese General Social Survey to investigate whether variables play a role in the electrification of private residences. The topic and the conducted study are interesting; However, before any final decision, the following comments need to be fully addressed:

1.       The abstract is sufficiently informative, especially when reading in isolation. However, it does not reflect the originality and its novelty over state-of-art. Adding some short sentences in this respect makes this section more flourish.

2.       Keywords are missing.

3.       Several significant statements in the first two paragraphs of the introduction are left without any suitable references.

4.       The authors mentioned some of the existing research gaps in the introduction, however, it is highly advised to devote a specific subsection to state the current shortcomings of the state-of-the-art. The reviewer suggests itemizing them.

5.       There are some English problems such as: "In this paper, we innovatively use the predicted average price of electricity is used as an instrumental variable (IV) of electricity prices to solve possible endogenous problems."

 

6.       "There are certain substitution effects between different energy types in household energy consumption (Silva and Cerqueira, 2017), such as the replacement of coal by electricity in heating, the replacement of oil by electricity in vehicles, and the substitution of natural gas and electricity in the most extensive cooking process in daily life." What about biofuels? The reviewer strongly advises the authors to mention biofuels (different kinds of biofuels) as one of the energy kinds for consumption in households. The authors can use relevant references to show the importance, for instance: day-ahead and intraday dispatch of an integrated Biomass-concentrated solar system : A multi-objective risk-Controlling approach. An innovative coalitional trading model for a biomass power plant paired with green energy resources.

Reviewer 3 Report

Dear editor,

How Efficient is China’s tiered pricing for household electricity: Evidence from survey data. There are some minor miss understanding that requires some modifications in the paper. After the following corrections paper may be acceptable for publication:

1.  The authors should improve the abstract with the highlight of results and add the Keywords: keyword 1; keyword 2; keyword 3 (List three to ten pertinent keywords specific to the 22 article yet reasonably common within the subject discipline.)

2. the authors should improve the methodology and the formula used .

3 the authors should correct the Table 1. Descriptive statistics of main variables.

 4. this part needs to be revised, some sentences need to be clarified:  the Table 4 show that the self-price elasticity coefficient of electricity is less 398 than 0. It is particularly important to note that in the low-income group, the self-price of 399 electricity is inelastic and insignificant. In the middle-high income group, the self-price 400 elasticity of electricity is significant and elastic, which shows that as income levels in- 401 crease, households' sensitivity to electricity prices increases l.

 

5. in the conclusion where the authors said that to improve the efficiency of the electricity market while ensuring the basic needs of low-income groups, why they didn’t think about the green energy like solution for the future .
