| 摘要: |
| 中国的能源价格机制尚未完全市场化，使得国内外能源价格走势存在差异，形成了国内外能源相对价格。本文首先采取非竞争型投入产出法测算出中国各出口行业的能耗，并按照能耗高低顺序将其划分为高、中、低能耗行业，进而采用小波时频分析方法，从“时域”与“频域”两个维度考察国内外能源相对价格对中国高、中、低能耗行业出口的差异化影响。根据实证结论，中短期内，国内外能源相对价格有利于高、中、低能耗行业出口，但效应从高到低依次递减；长期看，高、中能耗行业出口增长将导致国内外能源相对价格呈现缩小趋势。为兼顾缓解能源问题与促进出口贸易的发展，政府应积极改革国内能源价格形成机制，并采取针对性贸易政策以引导不同能耗行业出口发展。 |

| The Different Impacts of Relative Energy Price on Chinese High and Low Energy Consumption Industries Export ——Based on Wavelet Time and Frequency Approach |

| Abstract: |
| The energy price mechanism has not been market-oriented in China, leading to energy price differences in domestic and international market, which forms relative energy price between China and abroad. Firstly this paper uses the non-competitive input-output method to calculate the energy consumption of various export industries and divides the industries into high, medium and low energy consumption industries by the energy consumption density, further more adopts the time-frequency analysis method to analyze the differential effect of relative energy price on the export from high, medium and low energy consumption industries at both time and scale angles. According to the empirical results, the relative energy price is beneficial to the short and medium term export of high, medium andlow energy consumption industries，but the effect shows a decreasing trend from high to low energy consumption industry; meanwhile, the growth of export from medium and high energy consumption industries contributes to the reduction of relative energy price in the long term. In order to alleviate the energy problem and promote the export trade at the same time, the government should reform domestic energy price mechanism and adopt targeted method to guide the export development of different energy consumption industries. |
