I have, in the past, warned about the risks of drawing conclusions from Marketplace Pulse data. It is derived from publicly available information and their data and its conclusions may not represent what they claim it does.
And although some of their analysis like the number of new sellers is likely to reflect the truth, they offer no explanation for how the following was derived.
“According to Marketplace Pulse estimates, US sellers account for approximately $157 billion of Amazon.com’s $305 billion in third-party GMV, compared to $132 billion for Chinese sellers. The average US seller generates $884,958 in revenue, more than double that of their Chinese counterparts at $393,557. Globally, the pattern holds – Marketplace Pulse estimates Chinese sellers capture just 39% of third-party revenue worldwide, despite a majority seller share.”
And an obvious explanation of how the made their estimates is not present.
Does this seem accurate or meaningful? “The average US seller generates $884,958 in revenue, more than double that of their Chinese counterparts at $393,557.”
There is little doubt that the motivation for the Chinese influx is a Chinese economy which is much weaker than the US economy, and the need for greater export markets, but any of these sellers are like the increased number of sellers from countries like Pakistan, India, Turkey, and Sri Lanka on other internet marketplace are not succeeding.
I too use secondary sources of data for my own analysis of the state of Amazon, including some analysis of the FBA recalled merchandise in liquidation channels and see lack of success of many of the Chinese Amazon sellers.
Much of what the Chinese are shipping to FBA is not selling, and that which is has to offset the losses on liquidation of inventory. It is often cheaper to buy Chinese product from liquidation channels than it costs to make the product.
Its good to keep an eye on what the Chinese are doing here, but it would be far better if the source was more reliable or direct.
