Hi ricoplaza,
There isn't going to be any negative impact but it's also not going to be much benefit to you (if any benefit at all).
Just because you resubmit your sitemap, doesn't mean Google is going to crawl the URLs in your sitemap instantly.
For your e-commerce site, if you are wanting to speed up the indexing of new products or product categories, you can use the 'Fetch as Google' tool in Search Console to request faster indexing.
Also, news sites don't need to resubmit sitemaps to have their content indexed faster. Sites that are in Google news will have a news XML sitemap that is basically a direct feed for Google to index their news content instantly - no need to resubmit sitemaps.
Unless you've made some major structural changes to your site, you don't really need to worry about resubmitting your sitemap.
Cheers,
David
